How to install a sink siphon in a kitchen or bathroom

The process of installing a sink siphon in a kitchen or bathroom is not a difficult task. Labor costs are minimal - about 20 minutes of your time. From the tool, too, you will not need anything other than a screwdriver. This is with regard to installation on new plumbing. If you need to install it instead of the old one, then it will take a little more time. Here the whole thing will be in the dismantling of old equipment. Therefore, it is worth taking a few minutes to learn how to install a sink siphon and not resort to calling plumbers.

To begin with, we will conduct a small introductory part on choosing the best type and material.

Production material

Such devices for plumbing are mainly made of plastic and metal. The choice of material depends on preferences and its purpose.

So, when you need an attractive appearance, then a metal appliance will do. They are most often made of brass and have a glossy finish. Suitable for cases where there is no cabinet or cabinet under the sink. In this case, it must be practical and attractive.

Chrome-plated devices can be successfully entered into the interior. They are perfectly combined with faucets or heated towel rails. But beauty has a downside. Gloss will have to be looked after separately.

Bronze and copper are also used in production. However, they are not very good from a practical point of view. There are special care requirements, surface oxidation and the possibility of light damage. They are suitable only in case of combination in a certain interior.

The bulk of the current siphons are made of plastic. The material has rightfully gained its popularity for the following reasons:

  • Low price;
  • Differ in durability and small weight;
  • Resistant to various kinds of chemicals;
  • Easy assembly and installation;
  • It is possible to install in hard-to-reach spots;
  • The possibility of limescale formation is excluded.

PVC devices are the cheapest. They also have the smallest hydraulic resistance. However, if hot water is constantly drained, then it serves in the region of 6 years. A propylene product will cost up to 20% more. But if it is properly installed and used, it will last longer.

Kinds

In order to understand how to assemble a sink siphon, you need to understand its configuration. It can be one of three options:

  • Corrugated. The corrugated pipe on one side is connected directly to the sink. The other is for entry into the sewer. The gap between the inputs is bent in a zigzag. This part contains water. This is a water valve or water seal. It is necessary to isolate unpleasant odors from sewer pipes.
  • Bottle. It has a special part in the form of a bottle. She connects to the sink. It contains a liquid that acts as a shutter. The bulk of the water is removed through the drain hole.
  • Trubny. They have a similar structure with a corrugated device. The difference will be only in the material - plastic tubes are used. There is also a water valve in the curved part.

What should be considered before starting work?

Before we start figuring out how to install a sink siphon, let's pay attention to a few more nuances before starting work.

1. Before assembly, check that all elements and parts are included in the kit. It's worth checking out their quality. The kit should include the following:

  • Graduation withdrawal. A threaded insert is recommended to choose a metal one.
  • Rubber gasket. Installed in the outlet pipe.
  • Nuts are plastic. Diameter 32mm, 40mm, 50mm.
  • The cuff is conical rubber. Diameter 32mm, 40mm, 50mm.
  • Mounting cuff. Must have a soft plastic skirt. Diameter 32mm, 40mm, 50mm.
  • Screw. Preferably stainless steel. Any other material will rust.
  • The overlay is decorative. Installed on drain. It must also be stainless steel.
  • Gasket for installation in the drain. The materials can be rubber or silicone plastic. If the kit is made of polyethylene, then you should not take it.
  • Body directly. As the knee or the bottle said.
  • In the case of a bottle device, there should be a bottom stopper and a rubber gasket.
  • Drain rubber stopper.

2. Do not use acid sealant to seal joints. Its easy to define. If there is a smell of vinegar, then you can not apply it. The best option is inexpensive silicone. The best option would be to use only rubber gaskets from the kit.

3. It is worth considering the need to connect additional devices to the siphon. It could be a washing machine or a dishwasher. If yes, then you need to buy a device that has additional taps for connection.

Assembling the device with a bottle

Now let's get down to figuring out how to assemble a sink siphon. As everyone has said, it's easy. It is enough to perform all operations sequentially.

1. Check the drain grate for accuracy of fit. It happens that the seat in the sink is not enough for the grate. This point must be controlled, since it is not recommended to allow water to accumulate around the grate. The fact is that in such a case, bacteria and infections begin to develop there. If such a situation arises, the lattice can be tried to change. In extreme cases, install it simply on the sealant, without using a gasket.

2. The installation cuff is placed in the sewer pipe. First, it must be lubricated with sealant. Make sure the surface is dry.

3. Tapered threads are checked for burrs on the end surfaces. If present, delete them. It is also desirable to remove the chamfer.

4. The drain part of the pipe is cut to exact dimensions as required. Insert into cuff and secure. When fastening with a clamp, tighten its screw. The threaded part of the outlet pipe must be turned towards the siphon body.

5. If the spout goes down, place a square on the top of the outlet pipe on the sealant.

6. Installs a drain grate in the sink. Do not install the bottom gasket at this stage.

7. Place a thin O-ring into the groove of the plug. Treat it with silicone. You turn the cork.

8. In the case of a bottle form, if there is a valve, then insert it into the outlet pipe. At the same time, the damper at the valve opens outward.

9. The bottle is connected to the outlet pipe. On the sealant, the narrow part of the conical gasket is placed on the outlet to the bottle. Get it in a bottle. A side nut is screwed along the thread. But don't overtighten it.

10. The bottom drain gasket fits into the recess in the top nozzle of the bottle. Also use sealant. Lead to the drain pipe of the drain grate. Gently tighten the top nut of the bottle.

11. Slightly rocking the bottle, tighten the side and top nuts in turn with force.

12. If you are not using the holes for connecting the washing machine or dishwasher, plug them with rubber plugs. They must be included. If used, connect appropriate hoses.

Pay attention! All work must be done in one go, until the sealant has hardened. If you start moving the parts after it has solidified, then the sealing will not be reliable.

Corrugated siphon assembly

This option will be easier than the previous one. The number of parts and elements in it is minimal. The main part is the corrugated pipe. It has a water seal. She also plays the role of a drain pipe.

The entire installation process is based on connecting one end to the drain hole of the sink, and the other to the hole of the sewer pipe. Then a bend of the required size and depth is formed. Everything is fixed with a plastic clamp. After that, the assembly can be considered complete. You can use.

The installation technology is simple. Even a novice home master can handle it. For successful installation, it is necessary to determine the type of device and, following the assembly instructions, complete the work. Each unit comes with clear assembly instructions. Even if not everything is clear in the article, then following the instructions, you will definitely cope.
