How to install a drain in the bathroom

Drain pipe selection

In the bathroom, the drain pipe consists of several parts, but it is the siphon that is to be replaced, which is on sale in a small assortment.

Materials for arrangement can be bought at any specialized or hardware store.

If you do not consider the technological side and design feature, then it happens:

• Ordinary, equipped with a cork;
• Drain-overflow machine.

A distinctive feature lies in how exactly the cork opening system works, since in the automatic device the lever on the overflow is activated independently. You will not need to bend over and pull out the cork with your hands, as you can press the lever or wait until the system turns on by itself.

If we consider a group of simple siphons, then they only differ in branch pipes and the method of sealing joints, which are divided into gaskets: conical, straight.

Prevention of blockage of the drain hole in the bathroom.

As you can see, the procedure for cleaning the drain hole in the bathroom from hair is simple. But it takes time. Therefore, it is easier to avoid such situations.

• in the drain hole we install small nets that will detain not only hair or wool, but also small rubbish.
• periodically pour chemicals into the drain hole to clean the sewer pipes.
• once a quarter we clean the siphon under the bathroom.

And then there will be no need to puzzle over how to clean the drain hole of the bathroom from clogged hair.

This note is about one of the elements of the roofing system, which the customer, most likely, will never see if the builder or technical supervision does not show him, namely the drain hole in the gutter. The one through which water from the gutter enters the exit from the gutter (funnel) and then into the pipe.

Sometimes it's done like this:

So.

Stroke the "grinder" four times - and a hole is ready in the gutter. Of course, its shape can only be rectangular, and the edge will be uneven - with splinters and burrs. It is difficult to make such a hole large, because the design features of the tool impose restrictions. Scale flies from the angle grinder to the sides and after a short time, “saffron milk mushrooms” of rust may appear on the drain. Obviously, this way of arranging a drain hole in the gutter is a sacrifice of quality for the sake of speed and simplicity and a forced tribute to the low qualification of the worker. If you do not know how to use anything other than the "Bulgarian", where to go?

Sometimes they do this:

This hole seems to have been made by repeatedly drilling the gutter along the perimeter, after which a circle of metal was broken out or “bitten out” with the tips of scissors, and the resulting notches were slightly bent down with a hammer. You can guess why the drain is so small. Drilling hole after hole is hard work. If you increase the diameter, the number of holes will increase in proportion.

And sometimes they do it like this:

Here - let's try to unravel the technology - they drilled metal once. And moreover, not from the edge (so as not to damage the even line of the edge), but in the place that will then be completely removed. Drilled only to "bite" with scissors. Then, with small scissors for metal, they went to the perimeter of the hole and cut along the perimeter. Then they processed the edge with a small mallet, performing a reverse bend. There may be other variations on this theme, but in general, this is probably the case.

Question to the builders - which is better? Or - to rephrase - how would you like the gutter to be made on your house?

With your permission, I will not believe that the most common answer will be “I don’t care, as long as there is a hole for water drainage”.Because, in general, every builder (and not only a builder) understands that the drain hole should be no smaller than a pipe (or slightly larger), rounded in shape, with smooth edges - so as not to collect debris on burrs and notches. By the way, all builders also know that it is impossible to cut galvanized steel with a polymer coating (not only metal tiles, but any) with a grinder.

So, the correct option is in the last photo.

The technology for making a neat drain hole is easy to master. If you know how to hold a mallet and scissors in your hands, it turns out well the first time, it has been tested on yourself. But then you can safely show the gutter to the client and / or technical supervision, without causing questions and comments, but, on the contrary, receiving compliments, thanks and recommendations on word of mouth.

And to be proud to realize that one more step has been taken on the way to a high level of roofing craftsmanship.

How to clean a drain hole

There are a lot of reasons why there may be a blockage in the drain hole. It can become clogged not only with hair, but also with small rubbish, pellets from clothes, and the hair of four-legged pets. When all this accumulates in the drain, a lump forms, which is the reason that the water does not leave. Moreover, this lump becomes more and more, a bad smell begins to appear. Well, let's get started. In order to clean the drain hole, you should try the following methods:

try clearing the blockage under the cap covering the drain hole. Even if it seems to you that the cap is clean, check it anyway. It is very likely that you will find hair in huge quantities there. Drains with a Phillips plug are the most prone to these blockages. If you have a bathroom with a plug, you will need to lift the plug before cleaning. The guide plate is unscrewed, and only then can you remove the plug.

If the blockage from the hair is deeper than you expected, then you can use:

wire hook. Take the wire hangers, unwind and bend into a hook. Place a hook in the drain hole and pull out the clog

Important: you need to pull out, and not shove rubbish. Otherwise, you will definitely have to call a plumber.
plunger

Probably the most common method. But it will only help if the blockage is small. The plunger should be the size of a drain hole. Cleaning the drain hole with a plunger is easy, so if your drain is often clogged, it will become your indispensable assistant. How to break through the drain hole with a plunger?
Take the plug and close the drain, Lubricate the plunger with petroleum jelly and press it against the drain hole. Make about 10 sharp reciprocating movements. If the water is still standing, add hot water. Fill the tub with enough water to cover half of the plunger. The subsequent actions are the same as described above: we are trying to “break through” the blockage.

cable. A cable can help with serious sewer blockages. A cable is a twisted wire, at the end of which there is a handle (it can be wooden or plastic). The advantage of this device is that it can cope with a blockage, which is located at a depth of up to 9 meters. How to use the rope? Take the handle and insert the cable into the drain, with one hand hold and scroll the cable, with the other - push it deeper into the drain hole.
Now on the market you can find cables that have interlocking hooks that help get rid of hair in the drain hole.
If you feel that the cable is stuck in something, “stalled” - know that this is the place of the blockage. Now you need to repeat the back and forth movements several times and then you can clean the drain hole. You can then pull out the cable.

tape.To punch a drain hole, you can use any adhesive tape. Cut a strip of approximately 50 cm. Place the tape in the drain hole and move along the inner walls. Almost all the hair will remain on the adhesive tape. When you remove the sticky tape with hair, do not forget to wash off the remaining blockage.
chemical preparations. In the fight against blockages, you can use household chemicals. Ask the store clerk to suggest which remedy is best.

The main types of drain devices

There are several types of drainage systems. One of the most common options is a design in which the drain is fastened with a large locking nut. This fastening method can be found even in the bathrooms of houses built more than two decades ago.

Classification according to the principle of the device

Drain siphon systems used when connecting sinks are of three types: flask-shaped, knee and combined.

They differ in the type of construction:

1. Bottle or flask. The main structural elements are two cylinders immersed in each other. A tee is installed inside the flask of the device, distributing the liquid and forming a hydraulic barrier.
2. Pipe. The main element of the double-turn design is the “S” or “U”-shaped bend of the pipe, which forms the hydraulic barrier.
3. Mixed devices. In addition to the structural elements of the bottle design, supplemented by two partitions, they are equipped with a corrugated hose.

In bottle-type devices, the effluents entering the siphon move down the inner pipe of a smaller diameter. Having reached the bottom, the drains rise through the cavity between the inner and outer cylinder and are discharged into the sewer pipe.

Bottle siphons are beneficial in that even with the rare use of a plumbing fixture, the water seal in the sewer system does not dry out for quite a long time. This effect is achieved due to the fact that the output from the siphon is placed approximately in the middle of the flask.

Many owners prefer bottle-type siphons for the reason that, if necessary, several drains can always be connected to them. To do this, the design only needs to be equipped with an additional element.

Mixed-type siphons have proven themselves well in work. The corrugated siphon used in the arrangement of a mixed-type drain structure is a modified version of a conventional curved tube.

Unlike bottle and pipe counterparts, there are no models with sockets among the combined options, and therefore overflow systems and household appliances cannot be attached to them.

Division by material of manufacture

There are two types of sink drains available for sale, depending on the material of manufacture: those made of polymers and those made of metal alloys.

Polymer products are famous for their low price and ease of installation. Structures equipped with a corrugated pipe can be conveniently adjusted in length.

But the service life of PVC structures is relatively short. And the sealing properties of the assembled structures leave much to be desired. Therefore, all docking elements must be equipped with rubber gaskets during assembly.

In terms of reliability and durability, metal elements of drain systems are more beneficial. Models made of non-ferrous metals are most in demand in domestic use: brass and bronze. The harness made of such materials often has a chrome finish, due to which it acquires a rather presentable appearance.

To prevent the accumulation of mud deposits on the inner surface of the walls during the manufacturing process, manufacturers cover metal products with a protective chromium film.

Installation of metal structures is not particularly difficult.A hitch can only occur at a stage if you need to shorten the outlet pipe.

Siphons for non-standard equipment

For non-standard models of double "paired" sinks, siphons equipped with two outlets are used. Such siphon devices are connected to the drains of both sinks, and a little lower along the drain of the waste water, they are combined into a common flask.

It is not difficult to hide the drain systems of such structures in a niche, covering them with a decorative screen. But it is worth remembering that if the bend of the outlet pipe turns out to be too short, there is a high risk of an unpleasant sewer "aroma".

Do-it-yourself bathroom drain replacement

Experts do not recommend installing a siphon below the recommended level, since the height of the corrugation directly affects the rate of water draining. If everything is more or less clear with the installation, then how does such a part of plumbing as a drain work?

To replace the drain in the bathroom, you do not need to have special skills

Drain neck. It is installed in a cavity in the bottom of the bath, and it consists of 2 parts. The lower one is a branch pipe, which has an extension and a built-in nut. The top is a chrome cup. The tub must be placed between these elements, which are connected to each other by means of a long metal screw. A special sealing gasket is used to ensure tightness.
The overflow neck has the same structure as the drain, but it does not have a direct water outlet, as it is installed on the side in case the bath is too full to prevent the room from flooding.
Siphon, which can be of various configurations, and it looks like a removable curved pipe that is constantly filled with water. It is also called a water seal, which excludes the penetration of smell from the pipe into the room.

It is important to note that the volume of the water seal is of particular importance. If the ventilation in the sewer does not work properly, then it is quite possible that air is sucked in from the siphon cavity, respectively, the room will be filled with stench

You can exclude this if you take siphons with a deep water seal.
Corrugated connection hose to be used to divert water from the overflow into the siphon cavity. The pressure on this part of the drain is low, and therefore the hose can simply be put on a special pipe without using crimps. If the system is complex, then a compression nut and gasket must be present in it.
The branch pipe, which is responsible for connecting the siphon and sewage. It is corrugated and hard. It is simple and easy to set up. The first is recognized as more convenient to connect, and the second is more reliable. The main advantage of the corrugation is that you can adjust the length yourself without replacing this element.

The assembly is actually simple, but when buying a siphon and all the components of the drain, you need to check the complete set so as not to encounter a lack of elements, which, of course, will not allow you to complete the process without violating the technology.

How to connect a bath to a sewer

The scheme according to which the installation of the drain in the bathroom is carried out is understandable, but even with its clear implementation, some problems may arise if there is no work experience. The essence of the complexity is that some have technical thinking, others have economic thinking, and some just mechanically perform these actions.

It is worth noting that there is no particular difference between the assembly of two types of siphons. It is enough to carry out a few manipulations to carry out the replacement:

To replace the old siphon, you need to remove the old one, thoroughly clean the place where the connection to the bathroom is made, replace the gasket and connect.
To connect, you need to take the bottom overflow, put a gasket into it and substitute it from the bottom to the drain hole.With the other hand, the upper gasket is applied in parallel and the screw is inserted, followed by implantation. Then, while supporting the lower part of the overflow neck with one hand with the other, the screw is tightened with a screwdriver

It is important not to overdo it so that the body of the plastic neck does not burst. If there is a small leak, the screw is tightened a little more.
The overflow neck is installed in the same way.

The branch pipe is designed to remove excess water and is not placed vertically, directed downwards, but extends slightly to the side, which makes it easier to connect it to the neck cavity.
Then you need to connect the drain and overflow with a corrugated hose. It is strictly forbidden to shorten it sharply, as it will simply be bent.

Plastic pipes are good for draining in the bathroom

According to technology, it smoothly bends. If the joint is sealed with a nut, then it must be remembered that the gasket is installed with a thin tip to the cavity of the drain and overflow neck. First, the corrugations are put on, then the nuts, and only then the gaskets.

Purpose and design of the drain

The sink drain is a curved design, the main elements of which are a siphon and a drain pipe.

The outer element of the drain hole is a metal grill that protects the pipe from hair and small debris.

Located just below the drain hole, the siphon performs two key functions:

• Protects the drain pipe from clogging with waste penetrating through the hole in the sink.
• Interferes with distribution of the unpleasant smell coming from a sewer pipe.

The main secret of the siphon is in its bend.

Thanks to this constructive solution, the water does not completely leave the pipe, forming a kind of water seal, which prevents the spread of sewer "aromas" in the room.

The device package includes the following items:

• frame;
• exhaust pipe;
• rubber and plastic cuffs;
• decorative overlay on the hole;
• rubber stoppers;
• nuts and screws.

In case of clogging of the system, this siphon can be easily removed and cleaned mechanically, chemically or by means of the pressure of a directed jet stream. To prevent such situations, manufacturers recommend purchasing sink drains equipped with overflow.

The design of the system differs in that it is equipped with an additional tube made of flexible corrugation or hard plastic. It connects the hole in the top side of the sink rim to the part of the drain system that is located in front of the trap.

Such a zigzag tube is fixed in the desired position with a plastic clamp.

Purpose and design features

An overflow bathroom or kitchen sink drain is a curved design whose key purpose is to redirect excess water down the drain, thereby preventing the sink bowl from overflowing.

The device of the bath drain system is almost identical to the design intended for the sink.

Structurally, the overflow drain for a sink or sink consists of the following elements:

• siphon with a water seal - is a "U"-shaped element that performs a dual task: it prevents the exhalation of a fetid odor from the sewer and protects the drain pipe located below from clogging.
• drain pipe - made of corrugated or rigid plastic pipe and is designed to redirect wastewater to the sewer system.

The main secret of the functionality of the siphon is in its design. Due to the bend, the water does not completely leave the pipe. The formed water seal acts as an obstacle to the penetration of sewer "ambre" into the drain hole.

Such structures are convenient in that in case of clogging, it will not be difficult to remove and clean them mechanically or chemically.

Do you want to install a more durable device that is not so afraid of clogging? In this case, it is better to purchase a design in the form of an overflow drain for the sink. It differs from traditional models in that it is equipped with an additional tube.

This device connects the hole made in the upper side of the rim of the bowl with the elements of the drain system located in front of the siphon. This allows the overflow to divert liquid from the sink, thus preventing the bowl from overflowing.

From the outside, the drain hole is covered with a grill. It performs a protective function, retaining small debris and hair, thereby protecting the system from clogging.

Drain hole cleaning.

The reasons for the appearance of blockages in the drain hole, in addition to hair falling out naturally, are small litter, spools from clothes, pet hair. Accumulating in the drain hole, they form a lump that prevents water from passing through the sewer pipe. A lump of dirt and litter does not allow water to flow freely from the bathroom, collect further debris on itself, and, as a result, cause a foul-smelling blockage. So, let's act. In order to clean the drain hole in the bathroom, there are several ways. But initially we take the path of least resistance.

remove the drain cap and clean out the debris under it. Initially, before removing the cover, it may seem to you that everything is clean there. But visual inspection is deceiving. A huge amount of hair accumulates under the drain cover. This is especially true for drain holes with a cross plug. There are baths in which plugs are pre-installed. For this type of bath, before cleaning the drain hole in the bath, you need to lift the plug and unscrew the guide plate. Only after that you remove the cork.

To cleanse a deeper blockage of hair, choose any of the following methods:

• wire hook. You can safely use wire hangers (a bent wire hanger). We unwind the shoulders so that you have a hook with a handle. We insert the tip of the hook into the drain and pull out the hair or other objects that caused the blockage. Never try to push hair or other debris down the drain. Pull the hook towards you and pull the clog out, then throw it in the trash can.
• using a sink plunger. This method is suitable for a small blockage that prevents water from draining. The plunger should be selected according to the size of the drain hole. In principle, this is not difficult to do. Most often, the drain holes in both the bathroom and the kitchen sink are the same diameter, so the plunger will become your assistant for any small blockages. We close the drain hole with a cork, lubricate the plunger with petroleum jelly and press it firmly against the drain. We make about a dozen sharp reciprocating movements. If the water does not go away, then we clean the drain hole by adding hot water. To do this, we collect hot water in the bathroom so that it covers half the rubber bowl of the plunger. Then we immerse the plunger into the water at a drain hole at a slight angle, make several movements with it, and then abruptly pull it out of the water. It is impossible to push hair and other rubbish inside with a hook, since you can only aggravate the situation.
• cable. Serious sewer blockages starting from the drain hole are perfectly eliminated by a plumbing cable, which is a twisted wire coiled into a spiral. To make it convenient to rotate the cable, there is a wooden or plastic handle at its end. The length of the sewer pipe, which can be cleaned with such a cable, is from 5 to 9 meters.To start cleaning, insert the end of the cable into the drain hole and begin to slowly rotate the handle, pushing the cable forward with the other hand. The cable, which consists of hundreds of small interlocking hooks, easily grabs hair from the drain and removes accumulated debris. Feeling the tension in the cable, know ahead - a barrier of hair and litter. Therefore, we pull the cable back and forth several times. Then, breaking through the blockage, drain the water and pull the cable.
• Scotch. To clean the drain hole, you can use any adhesive tape that is in the house. Cut off a strip 50 cm long. Then we put it in the drain and draw it along the inner surface. This way all the hair will stick to the tape and you will clean the drain. After that, do not forget to turn on the water and wash off the small remaining particles remaining in the drain hole.
• chemicals. At a home improvement store, ask the salesperson for help choosing a chemical that can dissolve wool and hair in the drain. Otherwise, there is no point in buying household chemicals.

Pour or pour the drain and sewer pipe cleaner into the drain hole and leave for the time specified in the instructions, and then rinse with running water

We would like to draw your attention to the fact that you can not leave the product in the drain for less or more than the time specified in the instructions. In the first case, the action of household chemicals will be ineffective, in the second - there is a danger of deformation of the material from which the pipes are made

Also, when working with chemicals, you should follow the safety rules. Work with chemicals should only be done with gloves.
