1. The bottle siphon looks like a flask, which can be easily disassembled for cleaning and rinsing. The inlet pipe is connected to the drain, and the outlet pipe is connected to the home sewerage pipeline, which often stops functioning due to a clogged siphon. By the way, you can remove the blockage without a plumber. Simply remove the device, disassemble it and wash it.
2. The knee sewer water seal has a U-shape and to increase productivity, in the case of large quantity drained water, it is recommended to use the original pipeline with a diameter of 110 mm or use the same adapter. If you do not use the plumbing for 40 - 50 days, the water will evaporate from the plug, which will lead to the penetration of odors from the sewer into the room. Therefore, if you rarely use this sanitary point, use a different type of siphon or periodically fill it with water.
3. A dry water seal for sewerage copes well with the moment of drying out, and therefore is used especially in places of rare use, for example, in dachas. It is installed individually or together with a conventional water seal. And if you want to know how to make a dry water seal with your own hands, then simply place a tennis ball so that it closes the entrance to the sewer pipe. When water appears, it will float up again and provide fluid passage.

This type of product has two subtypes, namely: float and pendulum.

When the water dries out and the water evaporates, the float valve drops and shuts off the pipeline.

The pendulum subtype is based on the gravitational properties of materials and the ability to transfer the center of gravity. Some manufacturers have already begun to use molecular memory capabilities on these devices.

1. Corrugated tubular siphons are becoming increasingly popular due to the ability to accommodate curves of required sizes even in bottlenecks use. The advantage of this system is the ability to adjust the loop of the device after its installation, and also, the sink itself or other plumbing fixture can be freely moved without turning off the siphon.
2. Double-turn products can be with vertical or horizontal joining, which is especially in demand for shower stalls, bathtubs and bidets. Double-turn siphons have a special pocket for water formed by two opposing elbows made of corrugated or more rigid pipe.
3. A shower drain is used with a removable water seal that has a settling tank for heavy impurities.

Sewerage – a complex system communications, the purpose of which is the collection and removal of household wastewater. To ensure that the system operates without interruption and meets user needs, it is equipped with special devices. One of them is a water seal for sewerage. Despite the small size and simple design, it fully justifies its purpose - providing comfortable living for residents.

At 48 km in length, the Phase 1 network of Singapore's deep tunnel sewerage system passes through significant geology on the island. Conditions range from soft compressible clays to high pressure loose sands, to zones of very hard, highly abrasive, fresh granite and areas of fully decomposed rock. Conditions vary in some cases from meter to meter with ominous mixed margins in between. Everything involves the skills and abilities of people and machines.

The sixth and seventh cars passed a few weeks later as the last of them continued to struggle through the difficult mixed ground conditions in the north. For the most part, the 48 km alignment divides into two geological zones. For the other 30%, polymers were needed to create a plug in more permeable, lower standard permeable soils.

No matter where in the sewer network it is located hydraulic valve, its purpose remains the same:

• block water hammer to reduce the load on sewerage devices and pipes;
• prevent the penetration of unpleasant specific odors into residential premises.

If the water seal (or siphon) is selected correctly, a favorable atmosphere reigns in the house, and sewer network goes without repair for a long time.

The finding was discovered during extra work site investigation required by each construction contractor after the award of the contract and before the start of construction. T-05 southern drive Herrenknecht. On the downside, as a client, we have less direct involvement than is possible under conventional bid development and creation contracts. However, we are pleased with the design experience and will take the same approach to future projects. For contract project development teams, there is limited room for maneuver.

Water seal designs different types are different, but they are all, in one way or another, pipes with bends a certain shape, sometimes equipped with additional dead-end or dynamic devices.

The assessment and alignment of tunnels are fixed and the use of certain methods such as dewatering. Additionally, in all cases, contractors had to have their designs reviewed by an independent reviewer before they came to us for final review and approval. For the most part, the strategy worked. Cases of superficial settlement are higher than this long distance tunneling, due to ground conditions of a notoriously treacherous nature, and under ground infrastructure ground transport was small and had little impact - both by Singapore and international standards.

The water barrier is constantly in the siphon. If you do not use the device for a long time ( kitchen sink or toilet), the water will evaporate, and over time a smell will appear. The same will happen when you flush for the first time after a long absence. But with constant use, the volume of water in the water seal is constantly updated, which prevents stagnation and, accordingly, the appearance of an unpleasant “aroma”.

The same applies in reverse. In addition, granite is very abrasive. Discs break on impact with hard massive rock protrusions in mixed faces, and others wear into several flat spots, being squeezed and released by successive microchips from massive massive rock housing in the cases.

In the T-05 contract, a significant part of these interventions must be carried out on compressed air up to the maximum pressure of 4 bar permitted by Singapore law. However, the hydrostatic pressure was higher and freezing of the ground was required at one time to ensure sufficiently stable conditions for intervention. The maintenance also required repairs to excessive wear on the auger conveyor, cutting head and body structure. The space between this and the leading bulkhead is one large lock in the air.

However, when choosing a corrugated option, you should be aware of its only, but significant, drawback. The ribbed walls of the pipe seem to be designed to collect debris: food debris, hair, pieces of soap, sand and other dirt get stuck in them. Taking this into account, when installing the corrugation, the drain must be equipped with a filter in the form of a fine mesh grid.

If you do not clean the corrugated water seal for a long time, under the influence of dirt and excess weight it loses strength and elasticity. Over time, the folds wear out, begin to crack and let water through. After installing a flexible siphon, be sure to monitor its condition and clean it in a timely manner. You can guess that the pipe is dirty by the sagging that forms in places where grease and debris accumulate.

Operating principle of the overflow

Another type of siphon - with an overflow - can also be placed in a separate category, since it is necessarily equipped with an additional pipe. The main purpose of the overflow equipment is to protect the apartment from flooding if for some reason the water stops going down the drain when the tap is open.

Sinks on which they are installed this device, have an additional hole - in the upper part of the bowl, under the mixer. When the level of water accumulated in the sink reaches a critical level, liquid begins to flow into this hole and further into the water seal

Bathtubs must be equipped with an overflow system. This method prevents flooding, but, unfortunately, does not contribute to savings. If you want to run a bath and forget to turn off the tap in time, the water, having reached the overflow level, will safely leave the container and go down the drain - along with your money for paying for utilities.

Presented on the market as economical options made of plastic, still more durable, but less elastic metal models. The disadvantages of brass-bronze equipment are the complexity of installation and high cost. When choosing a device, do not forget to inquire about its throughput. If the overflow cannot cope with the volume excess liquid, it is useless and even dangerous.

Dry seal design

The design of the so-called “dry” valve is radically different from its hydraulic counterparts. It works on the “nipple” principle and is a threaded pipe with a check valve installed inside. As a result, water entering the device cannot flow back out, just as the smell does not have a chance to leave the pipe.

The installation of such devices is justified on the lower floors multi-storey buildings, as well as in places where water is used less frequently (in bathhouses).

Dry valves are generally not installed in kitchen sinks, the use of which most provokes the creation of blockages. But the devices work efficiently and last a long time in shower cabins built with your own hands.

The “dry” type valve does not require constant presence of water inside the housing. Even if it functions in conjunction with a knee device, it does not need to be monitored or adjusted

There are several types of dry devices:

• membrane, overlapping after draining the water with an elastic membrane;
• pendulum, tending to close instantly if no liquid is supplied;
• float valves that close the hole when water leaves the drain (acting like the fittings of a flush tank).

The latter are often made independently, arranging sewer lines in bathhouses.

The principle of operation of a float valve is considered the simplest. Light weight keeps the float on the surface of the water. As soon as it drains, the float moves down and blocks the drain.

If the sewer lines suddenly dry out due to infrequent use, thanks to the dry seal, the unpleasant smell will not bother you.

How to choose the right water seal

If you are installing or replacing plumbing fixtures (bathtub, sink or toilet), you will definitely need a siphon. To select a device that fully complies with plumbing, it is necessary to take into account a number of factors, including:

• dimensions of the assembled device;
• siphon type;
• the material from which the pipes and fasteners are made;
• number of drains or additional connections;
• protection against blockages;
• diameter of inlet and outlet;
• presence or absence of overflow.

Let's assume that for a kitchen sink the most suitable option– a bottle model that traps food particles. You can also use a knee device, but then all the waste will flow into the sewer pipe, and over time there is a risk of blockage.

If the project involves installing a sink or washbasin with two sinks, a device with two drain points will be useful. Its operating principle is the same, the only difference is in the design.

Before purchasing, be sure to measure the size of the space where the installation will take place. It happens that the siphon simply does not fit in the allotted space (this is especially true for the close gap between the bathroom and the floor). If you choose the right water seal, there will be much fewer problems with its installation and repair.

Installation instructions for automatic siphon

Installing a hydraulic bottle seal under a kitchen sink is quite simple, but under a bathtub is a little more difficult due to the inconvenient location of the drain system. We present instructions for installing an automatic siphon for the bathroom - an advanced device that you can install yourself.

A complete set can be purchased at your local plumbing supply store. It consists of three significant parts: 1 – plastic construction water seal + corrugated pipe; 2 – details for decorating the overflow; 3 – fastening elements for draining

First, we will equip the overflow hole. To do this, take the elastic gasket that comes with the kit and insert it into the hole on the wall of the bathtub. For a tighter connection, you can use silicone sealant.

We fasten the overflow structure in the hole, screwing it with outside chrome element. It is equipped with a rod on which the lamb will be held

Then we take the next part - the lamb - and try to carefully secure it to the rod with a bolt. To do this you will need a small flat head screwdriver that can penetrate through small hole in the side of the lamb.

We put the wing on the rod, insert the end of the screwdriver into the side hole and with a little force, but very carefully, tighten the fixing bolt

We pass the plastic part under the bathtub and insert the end with the rubber gasket into the hole. Place a standard chrome-plated part with a mesh on top of the resulting hole.

Among the fasteners we find a long mounting screw, which is responsible for fixing the siphon, and screw it in from the top side, holding the structure from below.

First, tighten the screw by hand, then tighten it with a wrench, but very carefully so as not to strip the thread. After completion, we check the strength of the installation

All that remains is to screw on the water seal element. First we string it onto the plastic outlet of the drain rubber gasket, then insert the knee lock. Tighten the outer plastic nut - the structure is ready.

Sewerage is far from being a bottle of perfume; its composition is such that it emits extremely unpleasant, sharp and persistent odors. To protect against unpleasant odors, they came up with a sewerage device called a water seal.

This simple device reliably cuts off inner space drainage from the living space, saving the inhabitants of the house from unpleasant contact.

How does a siphon work and on what principle does it work?

Wherever this device is located, its purpose is always the same:

• compensation of hydraulic shocks to limit loads on the gravity sewage system;
• preventing foul-smelling air from entering the living space from the drain system.

If the hydraulic valve is selected correctly and installed in accordance with the requirements for it, the room will remain fresh air, and the sewage system works for a long time without failures. This can be achieved by knowing what a water seal in a sewer is and using it correctly.

The designs of closing devices are different, but, in general, it is a product made of pipes, in the bend of which water is stored, blocking the lumen along internal diameter.

The water plug is constantly inside the pipe, periodically renewed. During a long break, the liquid in the hydraulic seals gradually dries out, allowing the smell to enter the room. This phenomenon is typical for buildings that are periodically visited, for example, country houses.

All elements sewer system interconnected. For example, drawing water into the riser during descent by equalizing the pressure in the sewer pipe. For the same purpose, and are used. They are used when there are no vent pipes in the building structure.

What are the types of hydraulic valves for sewerage?

Many designs of interrupting devices for drainage systems have been developed and are in use.

Their classification is possible taking into account various properties, but mainly takes into account design differences. Thus, up to six main types of sewer water seals are distinguished.

Hydraulic elbow valves

This device is easily identified by appearance– they have the shape of the Latin letter U. The advantage of devices of this shape is their strength, which allows you to freely install the system without fear of damage.

Most often, siphons of this type are used for installation on bathtubs and sinks. The material used to make the hydraulic valve is plastic or metal.

Simple plastic inserts are often disposable and cannot be adjusted. When dismantling, they are usually simply cut out.

Composite products allow you to adjust the position of the nozzle by changing relative position elements.

The knee is made with two bends - inlet and outlet, with the point of the second of them located 5-6 centimeters below the first. If cleaning becomes necessary, you can use several methods:

• with complete disassembly of the product, or;
• using a flexible cable with a brush at the end.

Some modifications are equipped with an additional inlet, which can be used when connecting a dishwasher or washing machine.

Bottle type devices

Dry water seals for sewerage

However, in the case of a sewer drain, you need to take into account long downtimes premises, which especially applies to shower rooms in baths. In this case, when the water in the seal dries out, air from the sewer freely penetrates into the room.

Therefore, in addition to a water seal, it is also common practice to install a dry siphon in baths. He is not special device and is mounted as part of the structure sewer drain. Such a valve is guaranteed to close the drain hole even without water.

Choosing a water seal for sewerage

If cleaning is necessary, the device is simply dismantled and then put back together.

1. The easiest way to connect is to kitchen sink bottle water seal.

To do this, you need to install the upper funnel into the hole in the sink and tighten the clamping nut. Before this, a gasket is installed under the funnel. Do not over-tighten the nut; it may dislodge the gasket from its conical seat and cause a leak.

After this, the casing is put on the pipe and secured with a nut. A corrugated pipe is led from the body to the inlet rubber bushing on the hole sewer pipe. The sleeve is selected to match the outer size of the hole, and the inner size to match the diameter of the corrugated pipe tip.

Just in case seats better process silicone sealant. To complete this connection it will take about 15 minutes.

How to make water seals with your own hands

The need for a siphon in the sewerage system is absolutely obvious. How to make this simple but important detail with your own hands? For this it is best to use standard fittings the right size. Of course, you need to have soldering skills plastic pipes using special equipment - a soldering iron.

Siphon is one of the mandatory elements connections plumbing equipment to sewer networks. It constantly contains a small volume of water, a water seal - it is simply necessary for sewerage, because... prevents the spread of negative odors. To choose a siphon, it’s worth understanding this issue, right?

We will talk about how the water seal fulfills its duties. The information presented to your attention will help you easily determine the types of device that are optimal for you personally. Reliable information will provide an opportunity to evaluate practical aspects and make an informed purchase.

The article sets out the design differences with utmost precision. various models, the specifics of the installation are described. For independent craftsmen will help with work step-by-step instructions, photo images and video tutorial.

No matter where the hydraulic valve is located in the sewer network, its purpose remains the same:

• block water hammer to reduce the load on sewerage devices and pipes;
• prevent the penetration of unpleasant specific odors into residential premises.

If the water seal (or siphon) is selected correctly, a favorable atmosphere reigns in the house, and the sewer network goes without repair for a long time.

The designs of hydraulic seals of different types differ, but all of them, in one way or another, are pipes with bends of a certain shape, sometimes equipped with additional dead-end or dynamic devices.

One of the most important conditions for the functioning of a water seal is the constant presence of water in its cavity, which acts as a barrier against the penetration of gases and unpleasant odors outside.

The water barrier is constantly in the siphon. If you do not use a device (kitchen sink or toilet) for a long time, the water will evaporate and eventually appear in the bathroom or kitchen.

The same will happen when you flush for the first time after a long absence. But with constant use, the volume of water in the water seal is constantly updated, which prevents stagnation and, accordingly, the appearance of an unpleasant “aroma”.
