How to connect a sink: recommendations from plumbers. How to connect a sink to a drain Connecting a double sink to a drain

Installing and connecting a sink in the kitchen seems like nothing could be easier. However, this impression is deceptive. You can feel this as soon as you start connecting the sink in the kitchen yourself. It is then that a lot of questions arise and various nuances emerge.

Today, there are several types of kitchen sinks in use, which differ in installation method and have different uses. The sink connection is also individual, however general rules still there is.

Main varieties

1. Group of overhead sinks. This species can be safely classified as a protozoa. The products are quite easy to connect and do not require large financial investments. The sink of this group is simply placed on a separate bedside table and acts as a countertop.
2. Built-in sinks. This type is so called because it is inserted into a previously prepared hole made in the countertop. As a result we have drop-in sink with quite attractive appearance and related amenities.
3. Underbench sinks. Mainly installed in countertops made of stone, various hard material or wood.

This makes it possible to obtain excellent sealing; moisture will not get under the sink, therefore, the countertop will not swell. However, it should be noted that the cost of such sinks is always very high.

Connecting a mortise sink

Plumbing fixtures of this type are made from the most different materials. They have a variety of sizes and differ in their shape.

In the case where the tabletop set is made of chipboard, perform self-installation Any man can do such a built-in sink. WITH stone countertop everything is more complicated, here you will need the help of specialists with the necessary equipment. Let's look at how you can install a similar sink in your kitchen yourself.

You need to start installing a mortise sink by making a hole that needs to be made in the countertop, taking into account its dimensions. For this purpose, the sink template is placed on the countertop, focusing on the place where the hole will be located. The template is leveled and secured with masking tape.

The established template is outlined with a pencil along the entire contour. After this, a second contour is drawn at a distance of 1.5 cm from the first. This is where you will need to cut the hole.

A jigsaw is used to cut the hole.

In order for the cutting to proceed smoothly, it is necessary, using an electric drill, to make a special starting hole in the tabletop, into which the jigsaw blade will fit. The drill diameter for such an initial hole should be 12 mm.

1. A jigsaw blade is installed into the drilled hole, with the help of which the hole itself is cut. Moving along the drawn contour, everything must be done slowly, carefully and measuredly.
2. The next step is to treat the edges of the tabletop with a special silicone sealant. Its use will help create protection against water ingress. The sealant should harden well. Wait a few hours.
3. Insert the sink into the resulting hole, observing how tightly the sides of the sink are in contact with the countertop.

At the same time, you need to check the connection of the mixer and all supply lines. The fact is that after the final installation of the sink it will be very difficult to connect all the hoses.

How to properly secure a sink?

To carry out this operation, it is necessary to apply double-sided tape, which is supplied with the sink, to the top of the countertop right along the edges. If there is no tape, a special sealant is applied again. The sink should fit into the hole made using a press fit, the resulting voids should be filled with the applied sealant.

When the sealant is completely dry, the sink is secured with special fasteners. This operation must be performed in a certain sequence.

First, the corners located diagonally are attracted, leaving a reserve for the final tightening. Then the parts are attached in the middle. Excess sealant must be carefully removed after it has completely hardened.

How to connect a sink in the kitchen?

First you need to connect the hoses through which water will be supplied to the water supply system.

1. A rubber gasket is installed between the fastening nut and the mixer; its task is to provide an excellent seal.
2. After connecting all the hoses to the water supply, the sink is connected to the sewer in accordance with a certain sequence.
3. First, the siphon outlet is attached to the sink. After this, a rigid pipe with a turn is connected to it. This pipe is secured to the sewer outlet.
4. After connecting and connecting all communications, the reliability of the connections is checked; there should be no leaks.

If you are thinking about how to connect a washbasin to the sewer and water supply system, you should initially determine who will be entrusted with the work.

It does not involve performing complex actions, therefore, if you have basic skills and the necessary tool You can cope with the task yourself.

Connecting the washbasin to the sewer

Having decided to install a sink or washbasin with your own hands, you first need to choose the installation location.

It should be as close as possible to the water supply and sewage system.

The mounting height of the sink is on average 850 mm.

If there is a leg, then the issue is resolved by itself.

Correctly connecting the washbasin to the sewer

Before you begin, you should prepare the following tools and materials:

• tape measure and building level;
• pencil for marking;
• drill or hammer drill;
• dowels, fastening studs, nuts and plastic inserts;
• wrench and open-end wrench;
• hoses;
• siphon;
• rubber sealing gaskets.

Tools you'll need

Now all that remains is to install the sink and connect.

The first step is to apply markings to the wall, noting where the sink will be attached.

After this, you need to screw in the mounting pins on which the sink or washbasin will be mounted.

It must be remembered that the part of the stud protruding from the wall should exceed the thickness of the sink itself by 1.5 cm.

This will allow you to easily secure the sink with special nuts after installing it on the fasteners.

After the fastenings are prepared, you can begin installing and connecting the sink.

Sink installation

Connection to water supply

To connect a sink or washbasin to the water supply, you will need to follow these steps:

This is how the sink is installed

• install the faucet on the sink. To do this, you need to screw one or two mounting pins into it, depending on the design, install hoses for supplying hot and cold water. They need to be tightened with moderate force, because after installing the faucet on the sink, it will no longer be possible to tighten them;
• pass the hoses through the corresponding hole in the sink;
• place a rubber seal on the fastening studs with reverse side;
• put on the pressure washer and attach the fastening nuts;
• tighten the fastening nuts with an open-end wrench, controlling their tension;
• fix the sink on the mounts previously installed in the wall or on the leg;
• connect the hoses for hot and cold water from the mixer to the corresponding outlets of the water supply system, fix them with a wrench. First, it is recommended to install an intermediate rubber gasket, which will increase the tightness of the connection;
• check the quality of work by turning on the water. If necessary, tighten connections.

After the connection to the water supply has been completed, all that remains is to connect the washbasin to the sewer.

The work is not difficult, but you should still read the step-by-step instructions first.

Connecting the drain to the sewer

To solve the problem, you need to follow this sequence of actions:

Connecting the sink to the sewer

• connect a siphon to the sink. For the kitchen it is better to use an S-shaped product, and for the bathroom - a bottle one. Last option more prone to blockages, so not suitable for the kitchen;
• connect to siphon drain pipe. For the kitchen you should use corrugated, for the bathroom – hard;
• insert the free end of the pipe into the sewer outlet. If the pipe is narrow, then you should use a special rubber adapter - a cuff;
• Check connections for leaks by running a certain amount of water into the sink.

Connecting a plastic siphon and sink corrugation

So P The connection of the sink to the sewer can be considered complete.

Before you get started, you should also know that it is not recommended to over-tighten pipe connections.

In this case, there is a risk of damage to the rubber sealing gasket.

A connected sink to the sewer looks like this

If a leak is detected when checking the connections, remove the cuff and dry it well.

It is resistant to moisture, hardens in just a few hours, which allows you to start using the sink after this time.

This is what a double siphon looks like

When you need to connect two sinks to the sewer, you should purchase a double siphon. It has two pipe outlets.

This will allow you to cope with the task much faster and easier.

Connecting a sink by professionals

In fact, the work does not involve performing complex actions.

But, if you doubt that you can cope with it yourself, it is better to seek help from professionals.

Our technicians will install and connect the sink in a matter of minutes, eliminating any installation errors.

Video

When connecting a sink, there is no need to contact specialists. The main thing is, before connecting the sink, carefully study the connection diagram and sequence of work.

Preparatory stage

It is extremely important to prepare everything first.

The entire preparation procedure can be divided into several stages:

• Determination of height.
• Marking.
• Installation of fasteners.

According to the standard, the sink is fixed at a height of 85 cm. A horizontal line is drawn at this height. If your sink has a pedestal or comes with a cabinet, then the height of its installation will directly depend on the height of the support leg or cabinet.

Hole marking

As for the markup, here you need accurate measurements for the hole of the fastener. There are two methods to measure the attachment points. The first option is to place the sink against the wall and place marks through the holes. The second method is more complicated; it involves taking all measurements with a tape measure. In both the first and second cases, it is more convenient to do the markings together. One can handle it if the sink has a support leg or cabinet.

Mounting the mount is the very last step of preparation. Holes are drilled in the marked places. A dowel is hammered into them, into which the required fasteners are screwed.

To connect the sink, it is imperative to use nuts, studs and special plastic inserts.

Stud mount

The stud should be screwed in to such a depth that when installing the sink there is sufficient distance for the fastening nut with a spacer placed under it. The stud should exceed the thickness of the shell by 15 mm. Now it's time to find out how to connect the sink to the water supply and sewerage system.

Connection to water supply

Equipment

The first step is to install the mixer. It is more convenient to install it when the sink is not yet attached to the wall. This is due to the fact that all fasteners are located under the sink.

Step-by-step instructions for connecting the mixer:

Mixer installation

When attaching the faucet, it is important to pay attention to the spout. If it is not rotary, it should be directed directly towards the center of the sink.

Now it's time to secure the sink to the wall. Place the sink onto the mounting pins. Then insert the plastic tabs and tighten the nuts with a wrench. If the bathroom sink has a leg, then install it at the same time. If the sink is in the kitchen, then here it either overlaps the bedside table or crashes into the countertop.

Studs for fastening the sink

After this procedure, all that remains is to connect the hoses to central water supply. Make sure there are rubber seals inside the nut.

After connecting the hose, make sure the connection is tight. You may just need to tighten the nut a little.

Connection to sewerage

Siphon assembly

To organize the drainage of the sink, it is necessary to connect it to the sewer. Connecting to the sewer system begins with assembling the siphon. The siphon, or rather the water seal, will serve as a barrier to unpleasant odors. If you are installing a sink in the kitchen, then use an S-shaped siphon. If in the bathroom, then a bottle will do. Although the bottle version has a number of disadvantages, for example, it clogs faster.

The sink is connected to the sewer in the following sequence.

This is how the sink is connected. Everything is very simple. If you have ingenuity, then all the work will be completed in a short period of time. Also, in addition, you can watch a useful video that will tell you the sequence of the sink connection process. If you have your own experience in this work, then write to us about it in your comments to this article.

For detailed video instructions for installation and connection, see below:

Installation plumbing equipment in the bathroom requires connection to the sewerage system and water supply system. For many apartment owners and novice craftsmen, this stage of work becomes a stumbling block. But, knowing the intricacies of installation and having everything at hand necessary equipment, you can connect the sink to the sewer yourself. Let us consider in detail the main points of the sink installation and connection technology.

The specifics of installing a sink depend on the type of plumbing fixtures. In addition to products of the usual configuration, today types of models such as “tulip” or “half-tulip”, double sinks and washbasins, which are mounted above washing machines, are widely popular.

“Tulip” - washbasin on a pedestal

Sinks of the “tulip” or “half-tulip” type are distinguished by a deep small bowl and a long pedestal. They may have monolithic structure or assembled from two parts: a bowl and a stand.

A bowl on a foot frees up space and hides communications

Small sizes“Tulip” washbasins make it possible to use such models when arranging bathrooms that are not very large in size. All communications are hidden in the stand. It also acts as a support for the bowl.

The only drawback of the design is the difficulty of cleaning the siphon during operation. Having removed the pedestal, if it is necessary to clean the siphon, you have to hold the bowl with your hands.

Double sink

Washbasins with two bowls were once only an attribute of respectable houses. Today the market offers big choice double sinks, and in a wide price range. You can find double models, the width of which does not exceed 80 cm. Thanks to their compact dimensions, they can easily fit even into a standard bathroom.

Sinks with double bowls are a win-win option for arranging a bathroom in a house with a large family.

The peculiarity of double-model plumbing is that the horizontal axes of the spout are deployed in them in different sides at an angle of 45°. Water is supplied to them through one spout pipe and, accordingly, descends through a common drain for both containers. IN different options Washbasins can be equipped with either one or two mixers. Therefore, installation and connection of a double washbasin is carried out according to the classic scenario.

For installation above the washing machine

Models designed to be placed above a washing machine appeared on our market not so long ago, but have already gained popularity among connoisseurs of functionality and practicality.

The peculiarity of washbasins of this type is that drainer in them it is located not in the center of the bottom of the bowl, but in the far corner

The depth of the built-in bowls is on average 20 cm. The siphon also has a reduced height. Installation of built-in washbasins is only possible by hanging them on the wall with anchors.

Ergonomic models – perfect solution for small bathrooms. But saving space comes at a price. The cost of products of this type is an order of magnitude higher than traditional analogues.

Sink installation and connection technology

Regardless of the shape and dimensions of the sink, the installation and installation technology of the device follows almost the same scenario.

To complete the work you will need a set of tools:

• electric drill with a set of drills;
• building level;
• wrench;
• screwdriver.

Installation of the structure

There should be no difficulties when replacing old plumbing fixtures with new ones. The only thing that can complicate the process is a discrepancy in the sizes of the structures being replaced, which entails a discrepancy in the location of the fastening points. The only way to solve the problem is by drilling new holes in the wall.

Tip: if you plan to change the location of the plumbing, make sure that the water outlet pipe does not form bends along the way.

Installing a sink on a cabinet is the easiest installation option

If the cabinet is already installed, you just need to place the bowl into the cut-out opening, checking the evenness using building level. The position of the tabletop can be easily adjusted by tightening the adjustable legs of the cabinet.

When dealing with new furniture that has not yet been installed, first try it on, making sure that the walls do not block the communication lines. To simplify the task of connecting pipes, the back wall of the cabinet is most often completely removed. Having installed the bowl in the cut-out opening in the tabletop and leveled its position, all that remains is to fix the structure. This can be done using anchor screws. Some craftsmen fix the structure by gluing it with construction silicone.

Placing the washbasin above washing machine, you will need to temporarily move the equipment to the side, having first marked its dimensions with a pencil on the wall.

Important! Distance between cover washing machine and the bottom surface of the washbasin should be 2-3 cm.

When installing suspended structure you need to correctly calculate the level of the bowl. On average, this parameter is 80-90 cm from the floor to the top side.

The plumbing located at this level will be convenient for use by both adult family members and children

Having determined the height of the bowl, mark a horizontal line on the wall. Having attached the bowl to it so that its upper edge aligns with the drawn line, determine the locations for the holes for fastening. It is more convenient to do this work with a partner: the first one holds the bowl, the second one makes marks on the wall.

Holes d12 mm are drilled at the designated points. Dowels are hammered into them and the mounting pins included with the plumbing are screwed in. The depth of screwing is determined so that the part of the stud protruding from the wall is 1.5 cm longer back wall shells.

Tip: to ensure reliable and static fastening of the sink, craftsmen recommend using thick screws and dowels or anchor bolts for fixation.

Connection to water supply

Proceed to installing the mixer. In most models it can be installed on already fixed washbasins. But there are options when you have to do this work in advance, since the structure is fastened at the bottom.

At this stage, it is important to maintain a 90° angle of inclination of the mixer itself relative to the wall adjacent to the washbasin

Procedure for installing the mixer:

1. Depending on the type of model being mounted, one or two mounting pins are screwed into the mixer.
2. Connect to the valve flexible hoses hot and cold water, tightening them with an open-end wrench, while applying moderate force.
3. Fixed hoses are routed through holes in the sink.
4. Putting it on the mounting studs sealing rubber bands and pressure washers, tighten the nuts with a wrench.

Important! The nuts must be tightened as carefully as possible so that they do not burst under pressure, cutting out the seals.

The main requirement when assembling the mixer is to ensure good tightness and reliable fit of all parts of the structure.

For sealing threaded connections and in order to avoid failure of flexible hoses, it is advisable to use sealing materials

The sink with the mixer is “planted” on permanent place, putting it on the studs screwed into the wall. Having previously placed the plastic inserts, carefully tighten the nuts. The fasteners are not tightened tightly until the structure is clearly adjusted horizontally.

When installing a washbasin above a washing machine household appliances connected to the same communication pipes that are used for the operation of sanitaryware. For this purpose, double plugs and tees are used. The only requirement is that the flexible hose of the washing machine must be connected to a separate valve.

Sewage connection

Connecting the sink to the sewer begins with installing a siphon. It is an S-shaped element that acts as a sump and drains water into the sewerage system.

There are 2 types of siphons on sale:

• elbow-shaped devices with a removable valve;
• bottle type, consisting of two concentric pipes inserted into each other.

If the sink has a hole responsible for the overflow, the siphon must be equipped with an additional tube to connect to it. Siphons are sold already assembled; the master’s task is to connect the siphon to the drain.

Installing a siphon is usually not difficult

The procedure is performed in several stages:

1. The siphon outlet is inserted into the sink, “baiting” it with bolts.
2. The outlet corrugated or plastic pipe.
3. The fixed outlet pipe is inserted into the sewer outlet.
4. Check all connections for leaks.

Advice: if the diameter of the pipe and outlet differ significantly, use a rubber sealing collar when joining the elements, and securely seal the joints.

If in the house cast iron pipes, plastic pipe The siphon is connected to the sewer using a rubber sewer coupling.

When installing a siphon, it is important to pay attention to a number of points:

1. There should be no burrs at the locations of the rubber seals. If any are found, they must be sanded or cut off. stationery knife.
2. Rubber seals should be dense, but at the same time elastic. Dried products will not provide proper sealing.
3. When putting on gaskets, the cone should be positioned on the opposite side of the nut.

When dealing with the “tulip” model, after installing the sink and connecting the communications, you need to move and fix the footrest. To prevent the structure from shifting, some craftsmen coat the contour of the connection between the leg and the bowl and the floor with glue or ceresite. But it is worth considering that such fixation may complicate the process of dismantling the stand if it is necessary to clean or replace the siphon.

Video tutorial: installation and connection of a sink on a pedestal

When installing the washbasin and connecting the system, consider a number of points:

• When planning to connect a double sink, choose a special siphon that has an outlet to two pipes.
• The height of the sewer outlet under the bathroom sink should not exceed 500-550 mm.
• When connecting to a sewer, it is important to reliably seal all joints, otherwise unpleasant odors will appear in the bathroom over time.

If, when checking the tightness of the connections, you notice water leakage, remove the cuff and, after allowing all the elements to dry, lubricate the connecting cuff with sealant and “put” it in its original place.

Installing and connecting a sink is not particularly difficult, but quite labor-intensive work. At some stages of installation you cannot do without an assistant. But in general, if desired, any House master will be able to easily cope with the installation of a washbasin on his own.

It is impossible to imagine the interior of a bathroom or kitchen without a sink. Installation of this product is quite simple and can be done independently, without the involvement of professionals. However, there are several nuances that must be taken into account when self-installation this type of plumbing. In this article we will talk in detail about the features of installing sinks of different types.

How to connect a sink in a bathroom? Installation largely depends on the type of washbasin. Today the following options are available:

• Tulip sink (on a pedestal);
• Wall-mounted (fixed to the wall using brackets);
• Overlay (installed on the countertop);
• A mortise sink is built into the furniture.

List of required tools

For installation you will need:

• Hammer, drill;
• Set of drills (for concrete and ceramic tiles);
• Measuring tools: tape measure, level, marker;
• Fumlenta;
• Set of open-end wrenches.

It is worth noting that according to SNIPs, the sink is installed at a height of 80-85 cm from the floor level. The exact height is determined by the height and personal preferences of the residents.

Connection to water supply

The planning of the washbasin installation site is carried out at the design stage. Water supply and sewerage pipes are brought to the installation site of the washbasin in advance. Connection for water is made using flexible hoses, for sewerage - through a corrugated siphon pipe. Initially, you need to turn off the water supply, after which you can remove the plugs from the water outlets intended for the washbasin. The instrument taps must be screwed to the sockets using fume tape (or other sealant). It is to these taps that the liner will be connected through the nuts.

Installation of mixer and siphon assembly

First you need to install the mixer and assemble the siphon. The mixer set usually includes a stud with nuts (one or more, depending on the design), washers, a gasket and connections for hot and cold water (they must be marked accordingly). We attach the connection to the mixer (don’t forget to tighten the nut with an open-end wrench). We fasten the studs, put on the rubber sealing gasket and install the mixer in the mounting hole on the side of the sink. On the other side, the gasket is also put on, and the entire structure is secured with nuts. Pay attention to the tightening force of the nuts - it should be strong enough, but without excessive compression of the gasket.

How to connect a sink to the sewer? This is done using a siphon. Initially, the top cover is attached to the drain and secured with a screw; the inlet pipe is installed below (do not forget to use a gasket). The “bottle” and corrugation are usually attached at the end of the installation, after which the siphon is connected to the drain.

Note. Plastic parts Do not clamp with too much force, the material may burst.

Installing a tulip sink

How to install a tulip washbasin correctly? First you need to try on the sink and mark the fasteners. Attention! Be sure to check the horizontal installation using a bubble level in two planes. Mark the mounting holes with a marker, after which you can proceed to drilling. It should be done to the depth of the dowel. We insert anchors into the dowel and hang the bowl on them. Afterwards, you should connect the sink to the water supply using nuts, and the siphon is connected to the sewer. You can install a pedestal on which the bowl will rest. In addition, it performs a decorative function, covering the water connection and drainage system.

Models on a semi-pedestal are quite common. In this case, the latter, like the bowl, is attached to the wall and serves more of a decorative function.

Installation of a suspended model

The installation principle is exactly the same. It is worth noting that main drawback Such options are that the connection system remains visible. In this case, it is worth purchasing a decorative siphon; most often, such models are made of polished steel and look quite aesthetically pleasing. First, we determine the height at which the bowl will be fixed (remember, this is approximately 80-85 cm), try it on and make markings. Check that the installation is horizontal. IN drilled holes special brackets are mounted (already included in the kit), on which the bowl is hung. After this, water and sewer connections are made.

If your bathroom is very modest in size, pay attention to compact wall-mounted washbasins that can be installed above the washing machine. In this case, you will need a miniature siphon of a special design (usually just a corrugation).

Installing a sink on a cabinet

First, check whether the cabinet is interfering with communications. Please note that it must be on adjustable legs so that it can be leveled horizontally. In the inner shelves of the cabinet, you may have to cut holes for the siphon; this is done using special crowns. Place the cabinet in place, then connect the water supply and siphon. You can try on the sink, check its horizontal position, after which you can mark the mounting holes on the wall. We install plastic dowels into the holes made, after which we screw the threaded pins into them; it is on them that the bowl will be held. We install a siphon grate into a special hole in the washbasin, install the mixer, after which the washbasin is finally installed in place. We complete the installation of the siphon and screw the liner to the mixer.

Kitchen Sink Installation

Kitchen sinks also differ from each other by type:

• Overhead, that is, mounted on top of the cabinet;
• Mortise, embedded in the tabletop;
• Recessed, built into or directly placed under the countertop.

The installation of sinks of the latter type should be entrusted to professionals, since they are often one piece with the countertop.

Installation of an overhead sink

Installation of an overhead sink is carried out directly on a kitchen cabinet of a suitable size. The ends of the sink are located along the perimeter of the cabinet. First, you should try on the sink and mark the mounting holes, screw the screws into the end of the cabinet, onto which the kitchen sink will be attached. It is worth pre-fixing the mixer and siphon, which after installation will only need to be connected. When installing, do not forget about the sealing gaskets located between the countertop and the sink body. They act as a sealing material to prevent leakage under the sink.

Installation of a mortise sink

Meet today kitchen sinks with two bowls. Their installation is carried out in exactly the same way as conventional ones. However, you will need a special siphon with two terminals. For undermount sink you need to cut a hole of the appropriate size. Please note from leading edge The tabletop should be retreated at least 6 cm, from the back at least 4 cm. We apply a sink to the tabletop and make a marking, to do this we outline the sink, we retreat 12 mm from the resulting contour, it is along the second line that the cut will be made. We use a jigsaw. The end of the cut is coated with sealant, this will protect the tabletop from moisture and further swelling. A siphon is attached to the sink, a mixer and a water supply are connected. Special fixing tabs are attached to the bottom. After this, the entire structure is installed in place, the pipes are connected to the liner, and the siphon is connected. That's it, you can check the quality of work.
