Replacing the bath tub

No matter how beautiful and expensive the bathtub is, but after the lapse of time it comes into an unusable condition. However, before changing it, you need to understand how the drain works. To drain the water in the bath special holes are provided. The pipe system allows for the tightness of the drainage system. This whole structure is called bath tubing. Proper installation will help to avoid a flood in the room, and, as a result, unpleasant showdowns with neighbors.

What the harness consists of

The piping system includes openings for drain and overflow. Water is discharged through the drain hole, and the overflow hole allows you to control the water level in the bathroom. The binding is not difficult to install, so it is very often used.

Having understood what the harness is, it's time to clarify the issue of the types of equipment used. The harnesses come in different types, they differ in material, installation method and their design. The material is mainly metal or plastic. Despite the fact that plastic is inexpensive, it can last quite a long time.

It is immune to the action of chemical reagents, therefore it is widespread. But despite its positive qualities, plastic is afraid of mechanical damage, which is a problem during installation.

This is due to the fact that during operation there is a need to cut or build up the elements of the plastic structure, as well as with the appearance of various notches that need to be cleaned.

Metal harnesses are no less functional, but they also have their drawbacks. They are quite difficult to install, they have a tendency to pollution. Yes, and they cost a little.

Reference! Metal bands are made of copper, brass or polished stainless steel is used.

Strapping options

As already mentioned, the bindings are divided into several types. The classification depends on two parameters: construction and material. The following varieties of design are distinguished:

  • universal type systems;
  • semi-automatic type systems;
  • automatic type systems.

Universal system strapping

This is the simplest and most common type. It is used in almost any bathtub: from acrylic, steel, cast iron.

The main requirement for universal systems is to withstand the distance from the central part of the overflow hole to the drain hole. It should not be more than 57.5 centimeters.

Components of the system:

  1. The mouth of the drain hole. Its kit includes a metal plate on which a plug is installed.
  2. Neck of overflow hole. She also comes with a pad.
  3. The most important part of the entire system is the siphon. It provides drainage of water into the sewer and prevents sewage odors from entering the rooms. Siphons are collapsible or solid.
  4. Corrugated hose. With its help, drain and overflow necks are connected. Installation is carried out by putting on the fitting and fastening with union nuts.

There is a grate on the outside of the overflow hole, and a receiver unit is connected from the inside. A drain pipe is attached to the receiving unit, which is connected to the lower outlet using a pipe.

For drainage of water in universal systems there is a plug that is inserted into the drain hole.

In universal harnesses there are practically no moving parts, so they are considered the most practical.

Semi-automatic systems

The design of this type of system includes a swivel lever that allows you to block the neck of the drain. It is very convenient to use, even if you are lying in the bathroom. With proper dexterity, you can even open it with your toes.

The principle of operation of this system is mechanical. The device starts operation when the valve is installed, which is installed on the neck of the overflow hole. The valve using a cable connects to another lever, which is located in the neck of the drain.

Rotation allows you to stretch or loosen the cable, which raises or lowers the plug that covers the drain hole.

Reference! The advantage of this system is its convenience. But the main minus is the fragility of the structure. Excessive force can damage the lever.

Automatic Type Systems

In automatic systems there are no cables or other fragile parts. Water is drained by pressing the plug.

Under the cork, a spring and a latch are installed. A spring, when a cork presses on it, pushes the latter out. One more press - and the drain is blocked.

Reference! All elements of the harness can have different colors. They are painted white, in the color of bronze, gold or silver.

The disadvantage of this system is the small size of the hole through which water flows, which leads to the accumulation of hair and debris.

If the device is of poor quality, then its disadvantage is the possibility of breakdown, which is very difficult to fix on your own. The solution to the problem is to completely replace the kit.

Reference! In order not to pay again, buy the device only from manufacturers that are time-tested. The best option is a metal harness.

How to install or replace the harness

Installation of a universal type system can be done on its own. Installation of semi-automatic and automatic type systems is best entrusted to professionals.

Before starting work, prepare everything you need:

  • drain system;
  • hacksaw for metal or grinder;
  • screwdriver;
  • napkins;
  • sealant.

The installation of the harness consists of several stages.

Removing the used strapping

Before you start installing a new drain system, you need to clean the entire bath and get rid of the old device.

Elements of the plastic system are easily unscrewed. In special cases, they can simply be broken off. To remove the strapping elements from the metal, you will need a grinder.

To dismantle all elements from metal, the first thing to do is to remove the drain neck, while trying not to violate the integrity of the enamel coating.

If it’s difficult to get to the bottom of the bathroom, it’s better to turn it over. Moisten a cloth in cleaning solution and remove any dirt.

Installation of mouths of discharge and overflow

Both of these elements are designed identically. There is a faceplate, a neck, a fixing screw and rubber gaskets. We remove from the neck all the bumps and burrs, we clean it with "sandpaper".

The drain hole must be wiped so that no moisture remains. Then you need to disconnect the grates from the drain and overflow tubes.

We install gaskets in the necks, where they are in contact with the throat, coat with silicone sealant.

The fixing bolt is installed in the center of the lining, on the other side we install it in the overflow neck, and then tighten.

Attention! When tightening, you don’t need to put a lot of effort, otherwise you can harm the parts.

The overflow system is mounted similarly.

Siphon installation

The siphon consists of two parts that need to be connected.

A plastic nut is installed in the inner part of the small element, and a rubber seal is placed under it. The wide part of the seal should be adjacent to the docking place.

The small element is inserted into the large, after which the nut is twisted. The small element must maintain its mobility along the axis.

Docking Parts

To connect the lower part of the drainage system and the upper overflow system with the corrugation, nuts are put on the ends of the pipes. In this case, it is necessary to tighten the gaskets having the shape of a cone. Their thick side should look at the nut.

The siphon is connected to the corrugation with an additional conical gasket. It is inserted into the hose and secured with a nut.

The corrugation is easily stretched, which makes it easy to insert it into the pipe. On some models, the corrugation connects without nuts. They just put it on the fitting.

After attaching the siphon to the drain neck, it must be secured with a nut. Do not forget about the gasket.

We twist the siphon until a creak is heard. In order not to damage the parts, do not apply excessive force.

When all the elements are in their places, we put the bath in its original position. Now you need to check whether everything is assembled correctly.

The floor under the siphon is covered with newspaper and water is supplied. If something is collected incorrectly, then the newspaper will immediately notice moisture. If leaks are visible, then parts of the siphon must be tightened.

If this does not bring a positive result, then it is necessary to lubricate all structural elements with silicone sealant.

Attention! If the product is used incorrectly, then even a quality-made strapping from any material will become worthless.

The drain and overflow system is not a panacea. She will not give full confidence that the neighbors will not be flooded by you. Always keep an eye on the set of water in the bath.
