Water seal for sewer: An item of sanitary ware

Water seal for drainage is an indispensable element of the sanitary equipment. It serves to prevent the flow of strong odors in the room of the sewage system. What is the principle of the device, there are some kinds of hydraulic gates, how to choose the right product and mount it? All the answers are contained in this article.

Odor trap: it is a required element of the sanitary equipment

The first step is to understand what the shutter. The element is a pipe bend, which has a certain shape. It can be additionally equipped with a dynamic or dead-end devices. In the lower knee siphon permanently located water-tube, which when unused for long periods the system may evaporate, resulting in penetration into the room of odors from the sewer network.

When the active operation of sanitary equipment liquid stock is constantly being updated, successfully suppressing foul-smelling substances. Waste water from the discharge pass freely through the siphon, which prevents clogging of the system.

Important! For the correct functioning of hydraulic lock in its cavity must be placed a certain volume of water that is necessary to prevent reverse gas and odors.

Why the need for a water seal? Siphon next lock hydraulic shocks, which greatly reduces the load on the pipes and devices. It also protects the premises from intrusion of unpleasant odors from the sewer system.

Hydraulic valve is rarely within a given plumbing device such as a toilet or urinal. Advantageously, it is mounted to the device. The apartment building is not installed sink, bath, shower or toilet without water seal.

Varieties of hydraulic gates depending on design

Depending on the design features are 6 types of hydraulic locks: crankshaft, bottle, dvuhoborotny, corrugated, dry and overflow system.

Crankshaft siphon with water seal is easy to learn in appearance. Its design resembles the Latin letter U. The siphon is made of plastic or metal. The first embodiment is represented by products of polypropylene, which are characterized by reliability, simplicity and ease of installation. cast iron or bronze used for the manufacture of metal siphons. Today, these models are less common due to their high cost.

The plastic devices can be produced in a one-time performance, they are not able to carry out the provisions of the adjustment element. In case of failure to perform a full dismantling of the product. Other models are made up of building blocks, which can move and rotate, adjusting the position of the nozzle. Fixing portions carried overhead by plastic nuts and clamps.

The knee has two inflection: the input and output. The lower position of the second member is located 5-6 cm below the ground. More reliable and durable embodiments are S-shaped structure. Cleaning products is performed using a special flexible cable with a brush on the end or manually after disassembly.

This sewage water seal is characterized by strength, which ensures free and easy installation of the system without fear of damage. Articulated siphons mostly installed on sinks, tubs and toilets. There are models with additional issue that provides the ability to simultaneously use a water seal for the washing machine.

Distinctive features of bottle hydraulic gates

Bottle devices usually installed under the sink in the kitchen. To understand how a water seal, should examine its structure. The product is arranged such that particles of food waste are retained, preventing clogging of the system to maintain its good performance. Simultaneously, a valve performs the basic function of which is to keep odors and prevent the possibility of their falling into the room.

The bottle water seal consists of pipes and the additional element in the form of bottles, which is a kind of a container for the collection of food waste. This container is located below the discharge pipe, it provides free access to the element. The container includes a vertical drain pipe connected to the sink, from the side portion thereof derived pipe for connection to the sewer network.

Bottle siphons are made of polypropylene, however in inferior durability issue knee analogues. This is due to the fact that the connection of all components can not withstand strong water pressure. However, for use in the kitchen bottle siphon fits most. Positive moment is also in a lower cost for sewage water trap 110 mm which is an average of 250 rubles.

For normal operation of the device must be periodically cleaned, since residues accumulate cavity vessel food waste, preventing the free flow of drain water. To clean the container, it should be removed. To do this, unscrew the nut consignment, the container is shaken out all the garbage. Then, wash the inside container using detergent and hot water. The device is installed in its place. The nut is tightened firmly to prevent water leakage.

Important! Bottle hydraulic locks are able to hold an object, which accidentally fell into the sink.

What is dvuhoborotny water seal bath

Dvuhoborotny siphon is an analogue of the knee tap, but has a more complicated device hydraulic lock. The drain pipe is connected to the device outlet pipe fittings. At this point, an additional set-lattice filter to retain hair and animal fur. It smoothly into the knee, connected to each tube, which is directed into the discharge sewer. The last element is located at a slight slant.

How to use the hydraulic lock by performing its cleaning? To do this, some models dvuhoborotny siphons can additionally be equipped with inspection openings, which are tightly closed with plugs, which makes it possible to perform an audit and cleaning water seal cavity from contamination. They are located at the bottom of the device. opening function may execute a removable knee fragment, located at the top of the device.

Important! Dvuhoborotny closures advantageously installed in bathrooms.

Waste dvuhoborotny type made of polypropylene. More expensive models elite class may be made of brass with chrome plated surface. When installing such products need a special tool, equipped with a soft sponge that will eliminate the likelihood of the mirror surface of the device damage.

Hydraulic-type bottle closures are characterized by strength, reliability and durability of operation. The design is easily adjustable thanks to movable components. It is easy to install and can be installed even in narrow spaces.

Advantages and disadvantages of corrugated hydraulic gates

Corrugated siphon type is represented by a modification of polypropylene which differs strength, flexibility and the ability to mount the regeneration of sewage systems in small spaces. Due to its ductility such a tube may be placed in locations where it is impossible to place other types of trap. This is the easiest option, of which consists of a minimum number of elements that do not require assembly.

Corrugated the siphon can be rotated to any angle and guide in the right direction. Such an option for sewage water seal with his own hands is often installed under the bathtub, because the model easily fits in a tight spot between the floor and the bottom of the container. One end of the water trap is connected to the drain, and the second - to a sewer pipe. With the help of the corrugations can also organize a sink with water seal in the bath of a private house.

Despite the many advantages, corrugated trap has only one, but significant drawback. The surface of the ribbed tube has a wall on which the garbage is collected in the form of hair soaps, sand and other dirt. When mounting a siphon, install the filter with a small mesh grille.

Important! If the corrugated gate for a long time will not be cleaned, it can lose its strength and elasticity under the influence of excess weight in the form of mud.

When operating the corrugated water seal should monitor his condition. Education sag is the cause of accumulation of debris. Folds will quickly wear out, crack and leak.

Characteristic features of the overflow system

Another type of product is a hydraulic trap with water seal basin or sink, equipped with overflow system. The device is equipped with an additional tube, thereby eliminating the likelihood of flooding the apartment in case of failure to discharge of water into the sewer. This tube is inserted into a specially created for him an opening which is located at the top of the sink or sinks.

Such a siphon to prevent flooding, however, increases the water flow. If included valve closed and the drain water when it reaches a certain level will expire on the overflow pipe to the drain. Odor trap with overflow system can be installed in a kitchen or bathroom.

Hydraulic valves with overflow system manufactured from plastic or metal. Plastic products have a lower cost and highly flexible. Brass, bronze siphons characterized strength, durability, assembly complexity and high cost.

Important! When selecting the siphon overflow should pay attention to the capacity of the tube, the apparatus further worked effectively.

What is a dry siphon sewer

The principle of operation and design of the dry water seal for drainage differ from previous counterparts. The drain pipe with a thread, a check valve preventing reverse flow of water and flow into the room of unpleasant odors from the sewer system.

Important! Such hydraulic locks advisable to install only in a shower, but they can become a cause of constant blockages in the kitchen sink.

Dry water seal for the shower stall is available in several varieties. In the embodiment, the diaphragm opening is covered at the time of expiration of the fluid through the elastic membrane of silicone in the form of a short sleeve. Pendulum siphons, through shutters, provide fast access to the hole overlap.

Float models operate on the principle of the toilet tank. The design is lightweight inverted cup, which edges are immersed. Easy float located on the surface of the water. After draining, sinking, it covers the drain. In some models, instead of a light bulb mounted float which, after expiry of liquid drops in an outer saddle, providing a tight closure of the drain hole. Such an embodiment can be made independently in the regeneration bath sewage wirings.

Important! In the case of drying sewage communication at a time when they are not used, the dry valve will not give an unpleasant smell to get into the room.

Characteristic features of the ladder with sewage water seal

When the draining is carried out with the entire floor surface is set street inlet with a water seal. It is mounted in the center of the floor with some bias at the time of the construction of the shower stall.

Street inlet shower with water seal consists of a hopper, a siphon with removable grille and outlet with the clutch. The first element is designed to receive water and exhaust it to the sewer. It is securely attached to the floor surface.

Tightness is ensured by a compound waterproofing membrane. Then the water flows into the siphon, which is represented by a small volume chamber, having an upper lattice filter and nozzle. Then drain poured through the outlet holes or container edges moves along the outlet fitting attached to the sewer pipe.

On a design such a mechanism reminiscent of the device of bottle type. However the siphon of the shower tray to a lower odor trap is not equipped with a removable cover that is used to retrieve the debris. This is due to the fact that the siphon body is hidden in the floor screed. All waste is collected in the inner glass, which can be easily removed from the casing and clean with detergent.

The design and material for the shower water seal with ramp

Sewer ladders may be made of plastic or metal. Polymer hydraulic locks for shower floor is not subject to corrosion, easy to install, it is characterized by durability and low cost. Metal articles can be made from cast iron or steel. The first embodiment has a high capacity and durability. However, because of the significant weight it is labor intensive to install. Cast iron ladders are suitable for swimming pools, toilets and laboratory space.

stainless steel ladders differ light weight, reliability, durability and ease of installation. They are usually installed in the medical and research organizations, because the devices meet the requirements of sanitary regulations. The receiving array can be circular, square or rectangle.

Sewer drain with a water seal is dry horizontal or vertical version. The first option, the height of which is 6-10 cm, often used for apartments or private homes. Also, it is mounted in tight spaces.

Vertical street inlet has a height of 15-18 cm, has a high bandwidth and advantageously used for showers. In apartments and houses set drainage gangway with a diameter of 50 mm, and in public areas - water seal for drainage of 110 mm.

How to choose a water seal for sewer

When choosing a water seal for drainage, the price is in the range of 300-600 rubles, to consider the following factors.:

• the dimensions of the siphon assembly;
• features of this type of device;
• material for pipes and fasteners;
• the number of discharges and possible additional connections;
• level of protection against the formation of blockages;
• presence or absence of overflow.

shutter type is selected based on the installation site. For the kitchen sink will be the best solution bottle design, equipped with a container for the collection of food waste. Bath is best mounted corrugated siphon, which can be located even in the most cramped conditions.

Option siphon shower selected taking into account the frequency of its use. If it will be used rarely, you should install a water seal for the dry bath or shower, which even when drying the water will not pass odors into the room.

The number of ports in the siphon must match the number of spouts, for whom this is a water seal. Another important criterion is the throat diameter of the device. it can be minimized, and the toilet and sink basin - the largest. Also considered outlet diameter when connected to a sewer pipe. For sinks and washbasins enough water seal for drainage 50 mm. Toilet, this parameter must be at least 100 mm.

Material for the manufacture of a hydraulic valve

From the manufacturing of the material depend on the reliability and durability of the device. Traditionally hydraulic locks for bath, bath and kitchen made of cast iron, whereby they were characterized by toughness, resistance to corrosion and a long service period. The disadvantages of the products include the provision of internal rough surface, which tends to hold up different pollution. This is ideal for industrial construction.

Most modern models hydraulic locks are made of polypropylene, thereby have a low cost. Devices characterized by durability, reliability, chemical inertness, lack of tendency to accumulate dirt in the cavity (due to the smooth inner surface).

Waste water seal dry premium made of brass or bronze coated with nickel, which gives the product an aesthetic appearance. Such valves are characterized by long period of reliable operation. stainless steel siphons demand for medical and care institutions. Such devices are well cleaned and disinfected, it does not affect their durability.

Installation sequence with their hands water seal for sewer

Install water seal for drainage in the bath, bathroom or kitchen is a simple exercise that you can do with your hands, not having certain skills. Under the washbasin or sink installation process is quite simple, but under the bathroom - more time-consuming because of the inconvenient location of the drain system.

Important! Any type of trap can be purchased complete with all the constituent elements in a hardware store.

Consider the installation of their own hands water seal for sewer 110 mm Bottle type. Included with the device includes a siphon, corrugated pipe, overflow design elements and fasteners. The first step should be equipped with an overflow hole. To this end it is inserted in an elastic pad which is fixed by means of silicone sealant. Then chrome decorative element is screwed to the rod, which is mounted on ram.

In the next stage is set for fitting clearance drain hole in the bath, sink or washbasin. It is screwed into the long fixing screw that fixes the siphon. First, he twisted his hands, then clamped the key. A plastic outlet worn rubber gasket. Next, insert the knee bolt. Finally, tighten the plastic outer nut. Odor trap through a polypropylene pipe is connected to the sewer pipe.

After installation is complete, you are testing the system. For this purpose the device is filled with water. It carried out inspection of all elements of the system for leaks.

How to install a sewer drain with a water seal

Installing sewer drain with a water seal dry is very responsible and laborious process. The correct execution of works directly determines the level of quality and long-lasting operation.

At the first stage floor rise in the shower or of bath room, which should have some bias towards the ladder, which will promote the spontaneous water allotted to the horizontal surface.

Street inlet is installed according to the instructions that came with your device. On the floor surface is laid insulation material, at the same time plays the role of insulation, which contributes to the quiet water abstraction from plumbing fixtures sanitary sewer system. For this fit polystyrene. Then the waterproofing layer is laid. You can use the web material with a membrane structure or obmazochnuyu mixture.

Next performed cement, which thickness is selected considering the height of the ramp and tiles thickness. Above the floor tile is laid with an adhesive solution.

Important! hydroseal lattice should be flush with the tile.

Possible causes of violations of the correct operation of the water trap

Hydraulic valve is simple in design a product which consists of a minimum number of simple elements. Therefore siphon failure is very rare. In this case, there may be situations that negatively affect its normal operation.

Failure of the device may occur due to a sharp reduction in the tubes malfunction pressure sewer network depressurization drain pipes, which may result in mechanical damage or improper connection.

If in a building on the upper floors the riser clogged at the descent of large volumes of water is formed in the discharge pipe, whereby the water is drawn from the water trap. This causes unpleasant odors. In this case, the question arises as to eliminate air lock in the sewers. Eliminate the problem by cleaning the riser or the installation of the vacuum valve on its end. Dry closures often begin to not work properly due to clogging of the descending float or meshed membrane.

Improper installation also adversely affect the operation of the device. The reason may lie in the non-compliance deviations, violating assembly sequence elements of the system, spontaneous flattening of the corrugations.

Important! If the siphon is quite old, he can no longer cope with its primary function of protecting the premises from intrusion of unpleasant odors. In this case, you need to perform well to disinfect water seal or replace the device with a new element.

If the room there is a sewer smell, check the efficiency of the water trap. Attention is drawn to the water level in the toilet bowl, which should be the same at each flushing. In the bathroom and in the kitchen checking can be done using a flame. To this end, as close as possible to the drain is brought match. On normal operation of the apparatus will indicate the absence of a flame.

If the flame undulates, enable the water for a minute, then again test the functionality of the device with a flame. If it still sways siphon defective.

How to make a water seal for sewer with your hands

How to make a water seal with your hands? The simplest design is a siphon knee hydraulic valve, which can be done independently. For its production need a plastic tube that is selected according to the diameter of the drain. It should be bent in the form of the letter U. Next, the upper part of the sewer pipe must be attached homemade siphon, fixing it by means of couplings.

The diameter of the fluid seal may not coincide with the size of the nozzle at the connection to the sewer pipe. In this case it is possible to use an adapter in form of a plastic ring having two different diameters, one of which must correspond to the size of the water seal, and the second - the parameters of sewage plum. For reliability of the connection grommet should smear silicone sealant.

Important! Bending must be below the siphon sewer drain hole 50-70 mm.

To create the dry hydraulic valve can be used tennis ball, whose diameter is slightly greater than the size of the pipe. Then, the chamber in which it will be. It connects to the sewer pipe. The ball will float until the gate stands a water tube. After complete disappearance of water ball as float chamber will fall to the bottom and overlaps the drain pipe.

Such dry water seal can be used in freezing weather. If the ball primerznet the pipe, the problem can be solved by processing device of hot water.

Water seal is an important device for comfortable and safe operation of plumbing fixtures. It prevents the penetration of the room odors from the sewage system. The device installation location depends on the choice of a particular type of trap, which can easily install yourself.
