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 sewer knee water seal has U shape and to improve productivity, in case 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 tube siphons are becoming increasingly popular due to their ability to accommodate required bend sizes even in tight areas of 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.

An integral element in the operation of plumbing products is a siphon with a “dry water seal”. Its development was based on innovative technologies that made it possible to solve many problems that arise when using classic siphons.

Design and operating principle of a dry siphon

There are devices with horizontal and vertical installation methods. The siphon design is a tube made of durable plastic. There is a tubular membrane inside. On one side of the cylindrical device there is a fastening to the sink, and on the other there is a membrane. The flow of water opens the membrane, and as soon as it passes, the siphon remains dry.

A tightly compressed membrane prevents unpleasant odors from penetrating into the room. Over the years of operation, the membrane is not able to stretch or shrink, since it contains a modern polymer with molecular memory. The smooth surface inside the siphon prevents sewer particles from sticking and creating a blockage. If the pressure in the system increases, the siphon acts as check valve. It inhibits sewer backflow.

Advantages of a siphon with a “dry water seal”

The main advantages of a dry siphon, which distinguish it from numerous analogues, include:

1. No stagnation of water in the structure. Standing water is an excellent breeding ground for harmful bacteria. Thus, the siphon dry water seal allows you to maintain cleanliness and hygiene in the room. Its use is especially important in rooms where the bathtub or sink is rarely used.

2. The water seal siphon does not require negative pressure to operate. This property contributes better ventilation sewer system without additional use of ventilation units.

3. The compact dry water seal can be easily installed in limited space premises.

4. Due to the fact that water does not remain inside the siphon, the product has found wide application in buildings where there is negative temperature. Freezing will not cause rupture or damage to the sewer system.

5. A siphon with a dry water seal has a high throughput, which is provided by a special membrane. If fat gets into the system, it will not harden, but will freely go down the drain. In standard siphons, fat, in contact with water, instantly forms a plug.

6. Researchers from an independent European laboratory have proven that the dry siphon operates completely silently. Even when passing a strong flow of water, the characteristic gurgling noise does not occur.

Before installation, you should measure the size of the drain hole, and, based on this, select required size siphon. The product is suitable for installation with a bathtub, shower cabin, washbasin, sink, bidet. It is also used in conjunction with washing and dishwashers, as well as for removing condensate from air conditioners.

If you need to connect 2 sinks located with different sides from the wall, you need to install an individual siphon on each one. To prevent water leakage, it is necessary to ensure the connection of the plumbing equipment and the siphon with a sealing gasket. Unlike classic-type siphons, there is no need to regularly dismantle and clean the product from blockages.

UK company McALPINE, with almost 100 years of experience, manufactures its products using innovative technologies. The world market trusts the brand for the traditional quality and practicality of its products. Latest development companies - with iPhone with dry water seal McALPINE 50 mm. It is designed to connect to a standard 50mm sewer pipe. Today, the product is the only one of its kind, and there are no similar analogues in the size for the 50th sewer.

Dry siphon 50 McALPINE serves to prevent penetration unpleasant odors from sewerage to housing. The product is equipped with a check valve that prevents liquid from flowing in the opposite direction. Unlike other siphons, McALPINE 50 does not have a water seal. Thanks to this, the product is not subject to freezing and the water seal will never fail.

The mcalpine siphon is a cylindrical design. There are nuts at its two ends. The case is made of impact-resistant plastic. Inside the tube there is an elastic membrane. When it unclenches, it allows the sewer flow to flow in only one direction. After the liquid has passed through, the membrane is hermetically sealed. In the production of the membrane, McAlpine developers used a unique polymer with molecular memory. Smooth inner surface The membrane prevents the contents of the flow from sticking to the walls of the McALPINE siphon.

Siphon installation

Installing a siphon with a mcalpine dry water seal will not cause any difficulties even for a beginner. One side of the product is connected to the drain of a shower stall, sink, washbasin, or bathtub. The compact model can also be used in conjunction with filters and air conditioners. In addition, the mcalpine sink and bathtub siphon is widely used with dishwashers and washing machines. The second side connects to sewer pipe with a diameter of 50 mm. The crimp nuts are easy to tighten and fit tightly.

An important design feature of the mcalpine dry siphon, which can be purchased in the SantekhMarka online store, is the ability to be installed in different positions: horizontally, vertically or at an angle. In this case, one should not forget about the direction of flow of the sewer system. During horizontal or inclined installation, the grooved side must be at the bottom. The mcalpine siphon requires periodic cleaning. Therefore, it should be installed in a place accessible for service.

Features and advantages of the siphon

1. With increased pressure in the sewer system, the siphon works as a check valve. In the event of a blockage, it is able to retain the reverse flow of liquid, preventing it from entering the room.

2. Thanks to the siphon, McALPINE engineers have greatly simplified the removal of condensate from air conditioning equipment. The product makes it easy to remove drainage from safety valves various boilers. The valve opens, allowing you to enter the system fresh air. Thus, there is no need to purchase a vent valve separately.

3. Self-sealing valve promotes home hygiene. Water does not linger in the structure, in which pathogenic microorganisms often multiply.

4. During operation of the siphon, there is no extraneous noise of “gurgling” water, which is typical for other siphons.
Fat entering the system will not cause damage, unlike other products in which fat hardens upon contact with liquid, forming a blockage.
