A sewage pump is an expensive and complex device. For its optimal operation it is necessary correct installation. In this article I will tell you the basic rules for installing sewer pumping systems. Let's start looking at the installation rules in order.

Installing a sewer pump on a toilet.

sewerage installation Sololift2 WC-1

More or less discussed here general rules installation of such pumps. Therefore, you need to read the instructions that come with the product. So, let's begin:

• If in pressure sewer a vertical section is provided, then it MUST be located at the beginning. The height of the vertical section varies depending on the distance from the general sewer riser and the diameter of the pressure sewer.
• Horizontal sections of pressure sewers must have a slope towards sewer riser. Slope value different manufacturers may vary, so please check your instruction manual for details.
• It is necessary to correctly select the diameter of the pressure sewer, based on the number of connected “sources”, that is, if in addition to the toilet, your pump is also connected to a shower stall and a washbasin, then you need to make a pressure sewer from a pipe of a larger diameter. Tables for selecting pipe diameters are available in the pump instructions. In addition, pay attention to the maximum consumption of your pumping unit, it must have time to pump out all the drains. Otherwise it will break
• For turns pressure pipeline It is better to use bends at 45º. This will reduce the likelihood of clogging in the pressure part.
• It is advisable to connect the sewer pump directly to the toilet. If there is a need to install a toilet through a pipe, then you need to clarify it in the instructions maximum length. For example, for Grundfos pumps this distance should not exceed 150 mm.
• Manufacturers prohibit installing sewage pumps in pits near the toilet. How this is explained was never clearly explained to me. But to maintain the guarantee, I recommend observing this point.
• The pumping unit must be firmly fixed to the floor surface.

Installation of a sewer pump for a shower stall and sink.

Now let's look at the installation rules for the shower stall and washbasin (sink):

• Sewage pump for shower cabins can be installed in any convenient location in the bathroom (can even be installed under a shower stall). But we must remember that the drains from the shower cabin and washbasin flow into the pump by gravity, so the non-pressure sewer system must be laid with slopes towards the pump.
• If you install the pump in basement or in any other place below the sewer riser, then first you need to make a vertical section of the pressure sewer. And then make horizontal sections with a slope towards the sewer riser.
• Select the correct diameter of the sewer pressure part. Selection tables are in the instructions for the device.
• Do not exceed the number of connected water supply points recommended by the manufacturer. And if you install additional point disassembly through a tee, then keep in mind that the sewage pump has a maximum flow rate and it should not be exceeded.

Installation of a kitchen pump for a washing machine and dishwasher.

Pump for pumping out gray waste from dishwashers and washing machine differs from the previous one in the ability to work with high temperatures drains (some models can withstand temperatures of 90º C for a short time). All other connection rules will be identical to those specified in the previous subsection. I bring to your attention another video:

Installation of a sewage pumping station.

Here are the most general rules for installing sewer pumping stations:

• • The sewage pumping station must be installed in a heated utility room. In addition, the room should not be flooded.
  • The station is attached rigidly to the floor using fasteners. This is necessary to dampen vibration from the station engine.
  • The selection of pipe diameters is carried out according to the user manual. The more sources of wastewater, the larger the diameter of the pipes you need to use.
  • It is advisable to make the pressure pipeline from PVC or PP pipes for gluing or soldering.
  • If it is necessary to make a vertical section of a pressure sewer, then it is done right next to pumping station. Subsequent horizontal sections are made with a slope of at least 1° towards the riser. The relationship between the height of the vertical and the length of the horizontal section of the pressure sewer is given in the instructions and varies depending on the diameter of the pipes.

Summary.

Before installing the sewage pump, carefully read the instruction manual, namely the part dedicated to installation. Then select the diameter of the pipe for laying the pressure part of the sewer according to special tables in the user manual. Only after this can you begin purchasing materials and installing the pump. That's all, write your questions in the comments and use the social network buttons.

Owners country houses, cottages and dachas seriously know that for complete comfort and living, not only high-quality water supply is required, but also proper sewerage. Sometimes there is no possibility to connect to the central sewer.

In this case, you will have to build a septic tank. Drains from the entire house will flow into this structure - from the washbasin, toilet, bath or shower, washing machine and sewer. If it is impossible to ensure gravity flow of the liquid, a pump for the septic tank will be required. Drainage or fecal devices are used as such a pump.

1 Types of pumps for septic tanks

Pumping units that are installed in a septic tank can be divided into several types according to design features and installation methods:

• submersible;
• semi-submersible;
• superficial.

1.1 Differences between fecal and drainage

Pumping units used sewer water work with liquids that have different properties and compositions. The main differences between the presented pumps include the ability of the fecal device to pump liquid of varying degrees of viscosity and in a liquid state, which may contain solid fractions.

The fraction size for this type of pump is 40-80 mm. To process large particles, grinders are installed in the unit. When processing large inclusions, the equipment's safety from wear is extended.

A septic tank drain pump performs the same functions, but has some differences. What stands out is that, unlike fecal pumps, this type of pump is capable of pumping out waste liquids with small particles in the substance. For smaller fractions, the pumps have special knives or mechanisms that, if necessary, crush various inclusions to a fine state. Fractions can have a size from 5 to 10 mm.

According to the standards, the sewerage system will be arranged in such a way that the septic tank is located underground. A septic tank is located above the septic tank. A septic tank pump pumps wastewater into a septic tank, sewer, or treatment facility. Septic tank pumps are used for irrigation land plot from a well or container where the liquid has been completely purified, as well as for draining water into filtration fields.

When pumping liquid from the first compartment, which contains solid particles and impurities, fecal pumps are used to pump out the septic tank.

1.2 Submersible units

Submersible pumps for septic tanks are made of cast iron or of stainless steel. This is due to the fact that the environment in which these devices operate is most often chemically active. Such production implies not only a body made of these materials, but also all its components and materials. The unit body is manufactured and assembled hermetically.

Your name this type pump received because its functionality is manifested after it is completely lowered below the level Wastewater. In addition to pits and septic tanks, these devices can be used to pump out pits or basements, as well as supply water from natural reservoirs. This can be accomplished in a short period of time, which is explained by the high power of equipment of this class.

As already mentioned, the submersible pump must be completely immersed in water before turning it on. To perform this task, you will need to attach to the device steel rope, rope or chain. Such equipment can be installed in 2 ways - mobile or stationary, but always leave the possibility of dismantling the equipment to carry out its repair. The container has special guides on the walls to which the device is attached. To pump wastewater, a pipe is attached to the bottom of the container. The pipe is connected to the pump using a flexible hose.

There are many models of this type pumps with different capacities. The parameters of the most powerful devices reach 40 kW. Such equipment is capable of pumping up to 400 cubic meters per hour of operation, while the lifting height can be up to 20 meters.

The advantages of submersible pumps include:

• compactness;
• productivity and efficiency;
• quiet operation;
• safety and reliability during operation.

A significant disadvantage is the difficulty of installing the unit and the need to lift it to the surface for periodic inspection or repair. The disadvantages include smearing the device with sewage while it is in the septic tank.

To provide reliable operation The following components must be additionally installed on the submersible pump:

• level float for automatic shutdown;
• Remote Control;
• check valve;
• grinding mechanism;
• thermal relays that protect the engine from overheating.

1.3 Surface models

One of the sewerage options is a septic tank with a surface-type pump. Such units are located not far from the septic tank on the surface of the ground, as well as in pits built for the septic tank. To pump out wastewater, a hose immersed in the hole is used. There are two fittings on the unit body that perform the following functions:

• for sucking wastewater from cesspool the inlet pipe is intended;
• The outlet pipe is designed to remove sewage outside the container.

The obvious disadvantages of these devices include their low power and productivity. The particle size they can pump is only 5 mm. The body of the device has poor waterproofing. This is due to the fact that it does not go into water.

At high humidity, the motor windings accumulate moisture and may short circuit, as well as internal corrosion of parts. Therefore, it is not recommended to install it for continuous operation. Even when located under a canopy, in winter period Over time, the moisture inside will freeze, which will cause the pump to fail.

The advantages of surface devices include their mobility, which affects ease of use. Ease of dismantling allows for quick and affordable inspection of the pump, as well as their repair and re-installation. The price barrier for them is lower than for other types.

Such devices are best suited for short-term switching on and pumping out small volumes of liquid up to 1500 l/h.

1.4 Semi-submersible units

Installing a drainage pump in a semi-submersible septic tank is carried out as follows. The working part, represented by the pump, is immersed in the pumped liquid, and electrical part(engine) is on the surface. The presence of a float switch helps automatic switching on or turning off the unit when the water level in the tank changes.

Electric motors of sufficient power are installed in these devices. Many models additionally have special grinders for large inclusions. Without grinders, they can pump fractions up to 15 mm in size, as well as debris and fibers.

Submersible and semi-submersible units have similar characteristics and parameters, but their costs differ significantly. Semi-submersible pumps cost thirty percent less than submersible pumps. This is due to the fact that their housing is made with less sealing.

2 Choice for septic tank

When choosing a drainage or fecal pump for a septic tank Special attention pay attention to the material from which the device is assembled. This is due to the environment in which the device will operate. The environment may be chemically aggressive, causing corrosion of the pump materials.

Another criterion for choosing a device for pumping out liquid is the power of its electric motor. But it is important to know that this rule may not always be true and the performance of the pump does not always depend on its power.

To understand the ideal performance of the unit, you should know that it must pump 5 cubic meters of water in one hour of operation. Naturally, this indicator is not a standard; there are models with five times more performance. When choosing the power and performance of the pump, you should pay attention to the volume of the container in which it will be installed.

For long-term operation of the device, the size of the particles passed is taken into account. If the unit is designed for low throughput, but will work with large fractions, then it will quickly become unusable.

An important factor is the height of the maximum rise of the liquid. To the lifting height you need to add the distance over which the liquid will be pumped.

For more information, you can look at reviews on the relevant forums or consult with friends.

2.2 Common brands

The following manufacturers are highly popular in the market:

Topas pumps are represented by a large selection of models. During operation they make little noise and are resistant to chemical exposure and corrosion. They are equipped with a compressor and can operate continuously for about two years.

The Tver septic tank is equipped with pumping equipment capable of pumping liquid in the required volume. It is recommended to install such devices in areas , where is the level groundwater exceeds the norm.

The Gilex company presents drainage and fecal pumps for septic tanks. Drainage units are mainly designed for particles with a size of 5 mm and work with slightly contaminated liquids. Fecal pumps are designed in such a way that they are capable of passing particles up to 35 mm in size and with contaminated liquid.

Pumps from Irtysh PFS 50/125.120. This unit has a power of 1.1 kW and is capable of dispensing liquid to a height of up to 6 meters. The productivity of the device is not small and is 16 m³ / h.

A common system for private sewer construction is the Septic Tank. To install a Septic Tank you will need professional help. Installation difficulties are offset by the advantages of this device.

The heart of the installation is located underground. The cleaning process begins with the first chamber of the septic tank, where household waste is discharged. There there is a breakdown into organic and non-organic matter. Inorganic components settle in solid form to the bottom of the chamber.

Cleaner water is pumped through pipes into the second chamber, where solid fractions are decomposed and the water is purified. After the second chamber, additional purification occurs in a biofilter. The water in the final stage reaches 75% purification.

Reading time: 7 minutes.

In the arrangement country house, cottage or dacha important point is a device issue autonomous sewerage, because the connection to centralized system often not possible. In this situation, a septic tank is installed and equipped with the necessary equipment.

The main element of equipment for a septic tank is the pump. His right choice will ensure the coordinated operation of the entire individual sewage system.

Types of pumps for septic tanks

Units designed for septic tanks can not only pump clean water like conventional pumps, but have the following features:

• are able to work with liquids containing foreign impurities;
• adapted for pumping out the contents of an autonomous treatment plant;
• indispensable during floods, for pumping water from flooded premises (basement, cellar, etc.).

Such specialized units come in the following types:

• superficial;
• submersible;
• semi-submersible;
• air;
• drainage

The choice of pump must be made taking into account the size of the septic tank, soil quality, quantity and feces.

Surface pumps for septic tanks

Such equipment is used for pumping water in local treatment plants. It can be placed at a remote distance from the septic tank (up to 9 m). With this placement, the pump remains on the surface, and only the suction pipe is placed in the well.

Surface devices can be compact units operating in manual mode or a full-fledged automatic station.

Surface-type equipment should be installed indoors, as it has poor waterproofing and is vulnerable to temperature fluctuations and moisture. If there is no suitable room, the equipment is placed in a pit or caisson, which is installed next to the septic tank.

Surface pumps, depending on the type of engine, are divided into electric, gasoline, and diesel, which come in two types.

1. Self-priming devices have a lifting height of up to 8 m. The suction hose is not filled with liquid.
2. Non-self-priming devices have a lifting height of up to 7 m. The suction hose is completely filled with liquid.

The advantages of surface devices include:

• portability;
• inexpensive cost.

The disadvantages of surface devices include:

• low productivity;
• the fraction of pumped particles does not exceed 5 mm.

Submersible devices for septic tanks

The devices are designed for pumping liquids with solid impurities. There are two types of devices: stationary and portable. Submersible pumps differ in the following features:

1. They have great power (up to 40 kW) and can process up to 400 cubic meters of liquid in 1 hour, lifting it up to 20 m.
2. The presence of wide flow channels makes it possible to pump solid impurities with a diameter of up to 40 mm and dense long-fiber impurities, which prevents clogging.
3. The noise of the mechanism is not audible. It is absorbed by the environment in which the equipment operates.
4. The devices have high performance.

Often, submersible models are equipped with additional grinding equipment and are equipped with:

• control panel;
• one or more floats;
• a coupling securing the device to the bottom of the tank;
• check valve;
• cutting mechanism of the grinding system;
• thermal relay that protects the device from overheating;
• waterproof electric motor with thermal protection.

Submersible units are manufactured from durable, chemically sustainable materials: stainless steel and cast iron.

• in suburban buildings;
• at manufacturing enterprises;
• in underground parking lots;
• in car wash areas.

Submersible pumping devices have one drawback. The temperature of the working environment should not exceed 40 degrees.

Semi-submersible septic tank pumps

Basic distinctive feature Such devices include the presence of a float, which holds the engine above the surface of the water, and the pumping mechanism itself under water. The drive of such pumps is electric. The steel body of the device protects the device from moisture and damage. The surface location of the drive makes it possible to use semi-submersible vehicles for working with liquids with temperatures up to 90 degrees. The engine will not overheat.

The advantages of semi-submersible devices include:

• simplicity, achieved by design features;
• ability to work in high temperature conditions.

A significant disadvantage of semi-submersible devices is the small fraction (up to 15 mm) of solid pumped particles.

Semi-submersible devices are not used in the industrial sector. They are used mainly for pumping out septic tanks that have a small volume.

Air pumps for septic tanks

A compressor for a septic tank is a necessary element common system autonomous sewerage. It performs the following auxiliary functions.

1. Complements the cleaning process by saturating the wastewater with oxygen. Helps the functioning of any treatment plant by creating pressure greater than that outside the septic tank.
2. They support the functioning of aerobic bacteria for the septic tank, which are necessary for the normal functioning of the entire treatment system.

For proper operation air pump must meet the following requirements:

• free access of air;
• Inside the septic tank, a density lower than that of compressed air is required.

Drainage pump for septic tank

They have the following qualities and technical indicators:

• type of unit – bladed;
• have the ability to absorb highly contaminated liquids;
• clean and waste water can be pumped out;
• the units are equipped with a filtration mesh that prevents large fractions of impurities from getting inside (up to 10 mm);
• protection of the device from overheating is ensured by the presence of;
• used in liquids with temperature conditions up to +40 degrees;
• standard cable length varies from 5 m to 10 m;
• The devices can be used for watering, irrigation and emergency pumping of water during floods.

Choosing a pump for a septic tank

When choosing a unit, you should pay attention to the following parameters:

• immersion depth;
• diameter of the suction pipe and supply pipe;
• distance from the installation site of the device to the collection point;
• maximum sizes of solid impurities that may end up in wastewater;
• temperature regime of wastewater;
• the productivity of the device in m³, which characterizes the speed of pumping liquid.

To calculate the lifting height of the wastewater, you need to add to the immersion depth the indicator of the length of the hose supplying the wastewater from the septic tank to the place of transfer. To get an accurate result, you need to divide the length of the hose by 10, since 10 m of length in the horizontal direction is equal to 1 m in the vertical direction.

Let’s say that to pump wastewater from a septic tank 6 m deep, when removing the tank 20 m, you need a pump capable of moving liquid from a depth of 6 m + 2 m = 8 m.

The equipment marking will help in choosing a unit for a septic tank.

1. “H” indicates that the pump body is made of stainless steel with possible application in an aggressive environment.
2. “F” indicates the pump’s ability to pump liquid with long-fiber inclusions and solid particles with a fraction of up to 35 mm.
3. The marking of the unit with only numbers indicates its ability to pump liquid with solid particles with a diameter of up to 5 mm.

Operation of a septic tank with a pump (video)

How to install a drainage pump in a septic tank?

Manufacturers often equip septic tanks with pumps according to the parameters specified by the customer. So for a septic tank of any modification, which is especially popular now, you can order a pump for pumping directly from the tank manufacturer. Our specialists will install the unit in the selected septic tank model.

If the septic tank is made individually, or purchased without a pump, then installing it should not cause serious difficulties. The pump must be installed in the following sequence.

1. We assemble an automatic connecting system. We fix one end of the coupling to the bottom of the tank, and connect the other to the pump.
2. We fix the guide pipes from the coupling along the tank wall, equipping them with a gate valve and a check valve.
3. A control panel is connected to the unit, the float switch response level is set, and the power supply is connected. It would be a good idea to use a voltage stabilizer in the system.
4. The unit is lowered to the bottom of the tank using a cable or chains along pre-installed guides.
5. We are performing a test run of the system.

Nuances of pump operation

1. Before starting operation, the device must be rinsed with clean water.
2. The audit should be carried out at least once a year.
3. Carefully monitor the level and condition of the oil. 1st revision 7 days after the start of operation.
4. The cable must be laid without kinks, clamps and sealed.
5. Compliance with all requirements specified in the manufacturer's instructions is mandatory.

Proper selection of a pump for a septic tank and compliance with operating rules will eliminate problems associated with the sewage system for a long time.

A septic tank pump is necessary if suburban area There is no possibility of constructing a gravity sewer. In order for the equipment to work properly for a long period of time, it must be correctly selected and installed. Read on to learn how to select a pump yourself and install it.

How to choose a pump

When choosing a pump for installation in a septic tank, the following parameters should be taken into account:

• product type;
• type of pump depending on installation;
• equipment operating parameters;
• manufacturer.

Main types of septic tank pumps

The following types of pumps are suitable for a septic tank:

• fecal.

The drain pump is different:

• ability to pump wastewater with particles with a diameter of up to 10 mm;
• ability to work at temperatures up to +40ºС;
• the presence of a special grille that protects the equipment from the ingress of large particles of contaminants.

A fecal pump, unlike a drainage pump, can process larger particles found in wastewater (up to 80 mm in diameter). It is for this reason that the device is most often used to pump wastewater into a septic tank.

In addition to the pumps required for pumping wastewater, equipment is also needed that is installed directly inside the treatment plant. The air pump for a septic tank performs the following functions:

• fill the tank of the treatment plant with oxygen for the active work of bacteria;
• contribute to the operation of the treatment plant.

The air pump is installed exclusively in treatment plants, the operation of which is based on biological method cleaning (work of bacteria).

Types of pumps depending on installation method

Depending on the installation method, pumps can be:

• submersible;
• semi-submersible;
• superficial.

The submersible pump is installed directly into the septic tank. The equipment is different:

• the presence of a durable body, which is made of stainless steel or cast iron;
• high power required not only for pumping wastewater, but also for lifting water from the bottom of the treatment plant;
• functionality. The equipment can be used for pumping out sludge, wastewater with large contaminants, and so on;
• high cost.

The only disadvantage of this type of pump is the inability to operate the equipment at water temperatures above 40ºС.

Semi-submersible pump appearance practically no different from submersible, but differs significantly in its characteristics:

• this type of pump can operate in an environment whose temperature reaches 90ºС;
• the pump is capable of grinding particles whose size is no more than 40 mm.

Semi-submersible and can be supplemented with a grinder, which allows you to pump wastewater with contaminants of larger fractions.

Surface pumps operate near the septic tank, that is, the device itself does not require immersion in drains. Benefits surface pumps are:

• portability - the ability to install equipment for dirty water away from the septic tank (distance no more than 9 m);
• low cost compared to submersible and semi-submersible.

Among the most significant disadvantages are:

• the ability to pump wastewater that contains only small fractions of particles;
• low equipment power;
• high probability of breakdowns when using equipment in adverse weather conditions.

Submersible and semi-submersible pumps are mainly used permanently, that is, they are installed in a septic tank and operate as needed, while surface pumps are used for emergency pumping of a treatment facility, for example, when the tank is overfilled and are removed for storage after work.

Selection of operating parameters

The choice of pump should also be based on the main operating parameters, among which are:

• equipment performance;
• pressure

Productivity is determined depending on the volume of the septic tank and the pumping speed. For domestic needs, models with a capacity of 25 m³ per hour are most suitable.

To determine the optimal pressure indicator of the equipment, it is necessary:

• calculate the depth of immersion in the septic tank;
• determine the distance over which wastewater needs to be pumped.

All major specifications pump can be identified by reading the markings on the equipment.

Pump manufacturers

Which pump is the best? When choosing equipment, it is recommended to pay attention to the following manufacturers:

• Gilex. The manufacturer produces different kinds pumps with different performance characteristics. Each consumer can choose the equipment that best suits its parameters;
• Aster. Such pumps are usually equipped with septic tanks of the same name. The equipment is durable;
• Tver. The company produces mainly fecal pumps with grinders, which, with stationary operation and proper maintenance, can last more than 3 years;
• Topas. The most common brand of pumps for septic tanks, which is widely popular, since the excellent characteristics of the equipment are complemented by low cost.

Pump installation

Installation of surface pumps does not require special knowledge. The equipment is connected to power, and the hose is lowered into the septic tank.

Installation of submersible and semi-submersible pumps is carried out in the following way:

1. At the first stage, the equipment is assembled. The power cable and outlet hose (pipe section) are connected to the pump body;

The elements of the system are fixed using insulating tape or special clamps.

1. A special elevator made of metal guides is installed in the tank of the treatment plant to lower and hold the pump. To reduce installation costs, the elevator can be replaced with a durable cable;
2. the pump is fixed in the septic tank to the selected design and connected to the power supply.

An overview of the drainage pump and its installation is presented in detail in the video.

Any pump requires periodic maintenance, which mainly consists of cleaning the equipment. The device must be cleaned at least twice every 12 months.

Basements of a private or apartment building are guaranteed to be protected from flooding if the drainage pump has been installed properly. Consequences of water supply network breaks, heavy rains, clogging drainage system often lead to the development of an unsanitary environment in the house and accelerated destruction of the foundation. Only a drainage pump can cope with water spills.

Distinctive features

Pumping equipment for dirty water belongs to the drainage category, and its use is similar to the use of fecal pumps. However, there are some differences:

• To a greater extent, fecal units are designed for viscous wastewater with fibrous organic inclusions, for the pumping of which a grinding mechanism is provided.
• The drainage pump, on the contrary, is not designed to operate in liquid conditions saturated with organic inclusions. At the same time, a drainage pump for sewage allows you to pump wastewater containing insoluble large fragments - pebbles, sand, silt of a certain size. As a rule, the permissible size of inclusions is indicated in the product passport.

Scope of application

The scope of application of drainage pumps is determined based on their design features:

• A series of prolonged rains, spring floods or heavy melting of snow. Similar situation can lead to the failure to fully cope with its purposes, which will result in the flooding of cellars, basements of buildings, ground floors etc. In this case, installing a drainage pump in the basement will allow emergency drainage work to be carried out.
• This unit can be installed on a permanent basis in the basement. A properly configured automation system will control the level of incoming groundwater and keep the room dry.
• Also, the installation of a drain pump can be provided for maintenance artificial reservoirs. Without this unit, it is impossible to maintain the required filling level in an artificial reservoir, or to carry out periodic drainage to replace and clean water.
• Accumulating tanks for drainage or domestic sewerage, storm sewers. Provided that they do not provide for independent liquid drainage.
• In addition, the installation of a drainage pump can be provided for discharging settled water into centralized collectors, natural reservoirs, or pumping it into reservoirs for subsequent technological use.
• Active sanitary rules prohibit even small car washes and workshops without local treatment facilities. Dirty water collected in primary collectors and pits, and then a drainage pump for sewage pumps it into the tanks of treatment facilities.
• These devices are actively used for irrigation agricultural work; they pump liquid from artificial and natural reservoirs to irrigated areas.
• This equipment is characterized by its versatility, it can be used not only for dirty, but also for clean water in systems autonomous water supply, filling high-lying containers.

Criterias of choice

If you need equipment for pumping water from a pool, bathtub, well or any other container, then the most the best option there will be a pump without a grinding mechanism. The main thing is not to use it in containers with large debris or polluted waters.

For kitchens and bathrooms, it is advisable to choose devices equipped with a cutting mechanism. Such devices perfectly shred objects that accidentally entered the sewer system, thereby preventing it from clogging. The installation diagram for a drainage pump with a chopper is presented below.

In any case, when purchasing equipment, it is important to focus on a number of requirements, which are given below.

Working conditions

Despite the fact that drainage pumps easily cope with pumping wastewater, their technical characteristics are limited by the degree of contamination of the liquid. It is important that this parameter does not exceed acceptable values.

High content of sand, large stones, dirt, silt can adversely affect operation of this device. That is, the installation of a drainage pump in the basement may be intended to eliminate flooding, but if it is necessary to drain the reservoir, a solid platform with flat surface. If the scope of work is construction site, then the best option would be a powerful fecal pump with a grinding mechanism.

Arithmetic calculations

When calculating the required power of pumping equipment, it is important to consider that 1 meter of vertical length corresponds to 10 meters horizontally. The rate of liquid removal will be low, despite the fact that the drainage units operate under conditions of constantly rising water. In order for the installation of a drainage pump to be justified, it is necessary to add to the height of the rise of the drains the length over which the discharge pipeline will be laid horizontally along the surface of the ground.

Unit selection

The selection should be made depending on where the drainage pump is planned to be installed (in the basement, etc.). It is advisable to install this type of equipment in a pit with a depth of 400 to 600 mm. This will protect the basement from water ingress.

Additionally, the unit can be equipped with a vertical float mechanism, which will start the pump as the recess is filled, while the floor remains dry.

If it is necessary to drain the tank as much as possible, install the drainage pump in the well on a hard surface. In this case, the unit will start when the drainage rises a few centimeters.

Installation

Self-installation drainage pump into a septic tank must be carried out in compliance with certain rules. For example, it is not allowed to install equipment intended for wells in septic tanks, and vice versa. Despite their external similarity, the models have different permissible power and operating principles.

It is also not recommended to work with budget options such as “Baby” or “Rucheek” and others - they cost a penny, but at the same time they are characterized poor quality assemblies. After pumping out the entire volume of water, they do not turn off, unlike models such as Makita, Gardena, Alco, Grundfos or Profer.

Step-by-step instruction

• First of all, it is necessary to find a pressure pipe at the pumping unit, to which the pipeline is connected, through which the wastewater will be pumped out. The clamp is carefully tightened at the connection point using a screwdriver or pliers.
• Most models are equipped with a float switch. If it is present in the model you choose, then it should be installed on the connected pressure hose which will prevent water from flowing back into the tank.
• Immediately before installation, you need to check the operation of the unit. Carefully read the instructions for it, manufacturers' recommendations and certificates. Another important point is determining the direction of the shaft. To do this, a household drainage pump is installed on a table or floor and connected to the network. If the movement is carried out in right side- this means the equipment is working correctly.
• the unit must be carried out exclusively in a vertical position. Make sure that the pressure hose is also directed vertically. Its end is directed into a container where the liquid will subsequently be pumped.
• Finally, the pump is sunk to the bottom of the tank and connected to the power supply.

Well cleaning

To make the process as simple as possible, it is recommended to purchase a special float with which the water level will be determined. Despite the fact that this type of device operates in automatic mode, it is advisable to monitor the process of its operation. It consists of the following steps:

• Effluent pumping.
• Destruction of growths of moss, silt and other contaminants present at the bottom of the tank.
• Cleaning the filter.

On average, cleaning a well takes 1-2 weeks.

Installing a drain pump on an air conditioner

During operation, the air conditioner produces a large volume of condensate, which must be discharged outside the room. For these purposes, drainage of the air conditioner is organized, which includes a drainage route, trays for condensate accumulation and a drainage pump.

Each equipment requires a pump of a certain capacity, which must significantly exceed the rate of condensation formation. The power or productivity of the pump is determined in l/hour, but it is important to take into account its ability to lift liquid, noise level and other characteristics.

The pump can be mounted in many ways. Therefore, in this case it is important to pay attention to the lifting height. One pump is capable of lifting liquid to a height of 3 meters, another - to 4 meters, etc. In other words, each pump has its own performance. Based on this, it becomes clear at what distance from indoor unit it can be fixed.
