Fittings for drain tanks with the bottom eyeliner. Fittings for the toilet cistern: how the drain device works and works

The first task after installing the toilet in place and connecting it to the sewer system is to install the cistern fittings. From the correct installation and quality regulation of this plumbing equipment will depend on the smooth operation of the entire system. fittings drain tank is a device that provides filling it with water after emptying during draining, automatic regulation of the amount of drained water and control of its overflow. How to properly install the tank fittings, read our article.

Drain tank valve device

The fittings for the toilet cistern consists of the following components:

located at an angle of the drain;
an overflow pipe installed on the side of the drain hole;
valve covers with rubber;
tank filling mechanism;
drain button mechanism.

Before you set up the toilet fittings, consider its main components.

Tank filling mechanism

This device ensures that the toilet bowl is filled with water to a certain level. This mechanism includes:

float fixture;
stop valve.

A float attached to a metal or plastic lever moves up or down as the water level in the tank changes. When filling the tank with water, the float rises, reaching maximum level. The lever connected to it closes the shut-off valve, and water does not enter the tank from the plumbing system. When draining the water, the float lowers, the lever opens the access of water from the pipe to the toilet bowl.

Water drain mechanism (bleed mechanism)

The flush mechanism is designed to access water from the tank directly into the toilet. Components of the descent mechanism:

drain siphon;
release lever (handle).

The siphon hermetically closes the drain hole, preventing water leakage. There are several types of siphons. The simplest kind drain siphon - the familiar “pear” to everyone - a rubber cylinder, similar in shape to a plunger. The device for draining water into the toilet bowl (raising the “pear”) most often is either a lever located on the side of the tank, or a handle on the lid, which must be pulled up to flush the water. More modern version descender - a button that is located on the front wall of the tank. Such a mechanism is most often installed on tanks that are built into the wall.

Installation and adjustment of fittings

After installing the toilet in the allotted place and then connecting the toilet to the sewer system, the next step is to install the cistern fittings: the video, offered as a small instruction, will help you to do this job correctly.

Installation of toilet cistern fittings

Let's consider the installation technology of the fittings of the toilet bowl:

Put a rubber gasket on the drain mechanism.
Install the mechanism in the tank, fasten with a plastic nut.
Put plastic or iron (depending on configuration) washers and rubber gaskets on the fixing bolts. Insert screws into holes. On the other hand, put on a plastic washer and tighten the nut.
Slide a rubber o-ring over the plastic nut. If a new ring is used, sealing is not required. If a ring that has already been in use was used, all joints should be thoroughly lubricated with sealant.

Pro tip: Careful inspection of all structural details can reveal minor casting defects. In this case, you will also need to use a sealant. Installation location sealing ring it is also necessary to coat with a layer of sealant, having previously cleaned it.

Install the cistern on the toilet seat and secure it with nuts.
Attach the filling mechanism. Attach the sleeve from the water pipe.
Put the tank cap back in place. Screw on the drain button.

Pro tip: Nothing should be additionally wound on the thread of the mounted mechanism to drain the water when putting on the sleeve. Try not to skew, so as not to strip the threads and spoil the part.

Armature adjustment

Installing a toilet and cistern should not cause much difficulty. But in some cases it may be necessary additional setting toilet fittings. So, to adjust the height of the drain valve:

Disconnect the rod from the overflow pipe.
Press out the cup retainer.
Move up or down the rack.

The water level in the barrel is adjusted as follows:

Adjust the position of the glass - raise or lower it along the guide, leaving a distance from the top of the glass to the upper edge of the tank at least 45 mm.
Install the overflow pipe above the maximum water level by 20 mm and below top level racks 70 mm.

To adjust the small flush, the small flush float must be moved up or down relative to the overflow tube. How to set up a full flush? Move the shutter (up or down) relative to the glass.

Adjusting the toilet fittings to full or low flush implies that moving the float or damper downwards increases the flow of drained water.

Constantly murmuring water in the tank and, as a result, the money that is paid for water supply flowing down the drain is a typical picture of a broken toilet. To solve this problem, you need to change the fittings for the flush tank. How to do this and how to choose the right one will be described in this article.

Everyone knows the sound of running water in the toilet. This sound indicates that it is time to repair the toilet. At first glance, the problem is very serious and insoluble without the appropriate knowledge and skills. However, this is only at first glance. In fact, toilet repair is most often the repair or replacement of broken cistern fittings. This procedure is simple and will not take you much time.

How is a flush tank arranged? In fact, it has two devices independent of each other - a filling valve (through which water enters the tank) and a drain column (it ensures the flow of water from the tank into the toilet bowl and, accordingly, flushing). The combination of these two devices forms the fittings for the toilet flush tank. Various manufacturers offer their models with some unique designs, different forms and colours. Despite such a variety, it is important to understand that almost all of them are universal (the probability that a universal fitting purchased in a store will suit you is about 95%). That is, knowing the type of yours, you can easily buy the fittings you need in any plumbing store. Within the framework of this article, fittings for built-in tanks are absolutely not considered. The fact is that they just do not fall into the above 95% of universal options.

And so, it remains only to find out what types of fittings are and how you can independently determine which one is needed in your case.

Types of cistern fittings

Since the reinforcement, as mentioned above, consists of two independent devices, the classification can be carried out according to:

fill valve type:
- with lateral supply - the valve is mounted on the side wall of the tank. Accordingly, the filler pipe (flexible hose from water pipe to the tank) fits from the side;
- with a bottom supply - the valve is mounted on the bottom wall of the tank. The liner in this case is connected from below.
Drain column type:
- with a button - to flush, you must press the button on the tank lid;
- with a stem - for flushing, the stem with decorative element at the end.

It should be noted that push-button columns, in turn, are also divided into two subspecies:

With a single flush - one button. When pressed, all the water contained in the tank is drained.
With a double flush - for such a column, the button is divided into two parts. Pressing one performs a flush using only half of the water contained in the tank, the other causes a full flush.

Fittings for a double flush cistern are considered more economical - you can choose the desired mode yourself. Columns with single and double flush are interchangeable, that is, nothing prevents you from buying and installing the one that suits you best, but it should be noted that the tanks have different displacements. With a small volume, a half flush may not be enough.

Under the push-button fittings in the lid of the tank, a hole of a larger diameter was made than under the stock. Therefore, in most cases, replacing a column of one type with a column of another will not work.

So, taking into account all the above, we get six types of fittings: with a stem with a side supply, with a rod with a bottom supply, with a single button with a side supply, with a single button with a bottom supply, with a double button with a side supply and a double button with a bottom supply .

Separately, it is worth dwelling on the fittings of the old model. Now there are still a lot of cisterns installed on the toilet with such fittings, or cisterns mounted on the wall and connected to the toilet with a pipe, in which old-style fittings are also mounted. It consists of a column with a stem (vertical or lateral) and a side filling valve. By virtue of design features and softer requirements for efficiency, the drain column from such fittings cannot be replaced with a modern one. It remains either to repair and adjust the fittings for the tank so that it does not let water through, and this is very difficult to achieve, or simply buy a toilet bowl with a modern tank, which is more preferable, especially if you have a water meter installed.

Summing up, we illustrate all types of fittings:

Fill valves. From left to right: bottom inlet, side inlet, old style

Drain columns. From left to right: push-button, with stem, old-style

How to choose fittings for a tank

Now let's move from theory to practice. When it comes to buying a new cistern fitting, it's natural to want to save some money. It often leads to some characteristic errors:

Despite the fact that the fittings are universal, their designs from different manufacturers can differ greatly. Therefore, it is wrong to try to look for only one broken spare part. Most likely, you will not succeed, and you will only waste your time. Conclusion - buy only the whole. In extreme cases, bring the entire fitting element (column or valve) with you to the store. There is a small chance that such a spare part can be found, for example, from defective fittings.
It is wrong to look for fittings for your particular tank, that is, exactly the same as it was. This is where it is important to remember that they are universal, which means that knowing the type of yours, with a high probability, any universal desired type will suit you.

Here the question arises, how to determine the type of your fittings?

To determine the type of inlet valve, just look at your tank, namely, where the flexible water supply hose is connected to it. If on the side, then you have a valve with a side supply. If there is no hose on the side, then the valve is with a lower supply. Look under the tank and see for yourself.

To determine the type of waste column, pay attention to what action is performed when flushing. If you press the button, then the push-button, if you pull the stem, then the column with the stem.

Determine the type of your fittings and choose the appropriate name for you (one of the above) - it is you who will need to tell the seller when buying.

Most likely, the store will offer you a choice of several options from different manufacturers and, accordingly, with different prices. What to choose?

The price range is quite wide - from 150 rubles. up to several thousand. To choose a quality one and at the same time not overpay, you should pay attention to a few nuances:

All connections of parts with each other must be strong. Detachable, as a rule, snap-on, should fit tightly into each other with a characteristic click. One-piece should not have backlash.
The seals must be good quality. Feel them. Soft, plastic and at the same time elastic, speak of the quality of both the gaskets themselves and, accordingly, the fittings in general.
Complete set - fittings of acceptable quality come with all the parts necessary for installation, including bolts that fasten the tank to the toilet. In some cases, valves are completed with spare parts (usually gaskets). Pay attention to the quality of small things. Unscrupulous manufacturers do not pay due attention to it. As a result, the quality of components is low. This should alert you.

Generally speaking, you need to know that the price of acceptable quality rod valves starts from 10 USD. e., for push-buttons - from 15 c.u. e. At a price of 30 at. That is, you can buy very good fittings with an increased resource (as a rule, this is reflected in the extended warranty period).

So, the armature is bought, it remains to mount it.

Rebar replacement

Replacement of fittings begins with the dismantling of the old one. In some cases, there is no need to completely change the fittings. It is enough, for example, to change only the drain column or the filling valve. If you change the column, you will have to completely remove the tank. Replacing the filling valve will not require this. In any case, you must first dismantle the old elements. Let's take a look at this process step by step. specific example. As an experimental sample, let's take this toilet:

It can be seen that it has a one-button armature with a lower supply. The procedure for replacing any other, including a rod one, for example, with a lateral supply, will not differ much from that described. Differences in operations will be indicated.

All work begins with shutting off the water at the inlet to the tank or the entire water supply line. After that, it is necessary to flush the water in the tank into the toilet.

1. Dismantle the button. In our case, it turns counterclockwise. It happens that the button is attached to the lid of the tank. The cover will then be removed without dismantling it. Then just go to the second step. For rod fittings - unscrew the decorative knob on the rod and unscrew the trim that closes the hole in the tank through which the rod passes (of course, if it was screwed).

2. Remove the cover and see this picture. In the center is a drain column. Side filler valve. If the length of the supply hose is sufficient to remove the tank and put it on top of the toilet, then proceed to the next step. Otherwise, turn off the eyeliner.

3. The drain column is collapsible - it consists of two parts. To make it easier to carry out work, we dismantle the upper part. To do this, rotate it by 90 ° (it will detach from the bottom with a snap off):

and take out:

Will stay inside Bottom part columns. On the sides of it are visible bolt heads that secure the tank to the toilet.

4. Unscrew the fixing nuts under the tank. As a rule, this can be done simply by hand.

After draining, a small amount of water will remain. When you unscrew the nuts, this water will flow out. So put on a rag.

5. Nothing prevents now to lift the tank up and put it on the toilet for the convenience of subsequent work.

The sealing gasket remained at the landing site:

6. The dismantling of the tank in our case could be done without first disconnecting the liner. If it is necessary to change the filling valve, then we perform this operation now.

Flexible hoses are wrapped and turned away by hand. The key is used only when absolutely necessary.

7. Unscrew the column fastening nut:

and valve nut:

8. We take everything out of the tank. Here, in fact, this is the dismantled fittings:

Now you can start installing the new fittings. All operations are carried out in reverse order, the only caveat is that for convenience it makes sense to put the gasket between the tank and the toilet on the mounting nut before installation.

The whole operation takes five to ten minutes. Threaded connections, as mentioned, are wrapped by hand and only if necessary are tightened with a wrench.

You can endlessly try to fix old leaking fittings, surprised every month by huge bills for consumed water, or you can spend 10 minutes and solve the problem for a long time by simply replacing the fittings completely. How to do it, you now know.

The fittings of the toilet bowl are a kind of “stuffing that provides work on the collection, retention and discharge of water. The material for the manufacture of fittings can be plastic or metal (brass, steel).

In this article, we will get acquainted with how to adjust the fittings in the toilet cistern, as well as with its types and features.

Primarily modern models toilet bowls are equipped with plastic fittings. It is quite durable, not subject to corrosion processes and the negative impact chemical substances present in the water.

The operation of the toilet bowl is directly dependent on correct operation shut-off valves, which are responsible for draining and supplying water. Today in the market of sanitary products you can see a lot of different models of this device. Moreover, there are not many types, since the valves are of the same type, suitable for different modifications.

Shut-off valves by design can be separate and combined.

Previously, only a separate configuration was used for the toilet device. In it, the installation of the filler and drain valve takes place separately, and they work autonomously. The operation of the filling valve is controlled by a float.

When the water in the tank rises and is blocked by a float under the action of thrust.
The drain assembly is a neck with a valve.

The valve is of two types - air and mechanical. Operated by pedal, button or key.

The advantage of shutoff valves is that in the event of a breakdown, only the damaged unit can be replaced or repaired, rather than changing the entire system.

This affects the family budget and facilitates assembly and disassembly work. Therefore, the use of such systems is relevant at the present time.

Elite class presents latest models products that use stop valves in a new design. In her general system connects the drain and fill valves.

Setting up this type of fitting is quite complicated. But at correct installation ensures safe and trouble-free operation of the unit.

The disadvantage of this system is the need for complete replacement in case of breakdown and difficult repairs.

Shutoff valves are also distinguished by the material of manufacture.

Mainly used for its production polymer materials. The quality of the materials that make up the plastic determines the quality of work and durability.
Metal fittings are distinguished as the most durable and durable. These materials are characterized by moisture resistance and resistance to mechanical stress.

Usage single shut-off metal fittings provided by manufacturers only for elite models. Separate systems can be installed in any toilet.

Top and bottom shut-off valves for the toilet

Shut-off valves are divided according to such criteria as the installation site and the method of water supply.

The design of the system will depend on which side of the barrel it is built in, which will definitely be taken into account when replacing damaged elements.

Differences in the installation have fittings with upper and lower water supply. Both systems involve the closing of the valve by the action of a control rod, which is connected to a float, which is a container made of plastic or foam.

When installing fittings, careful balancing must be carried out. This is necessary for the productive operation of the system, which is dependent on the water level of the drain barrel.

In domestic toilets, fittings with an upper water supply are installed.

This system is placed in the side of the tank.

The disadvantage of this design is the noise that the system creates when supplying water.

Toilet bowls foreign manufacturers equipped mainly with shut-off valves with bottom water supply. This design is silent, more comfortable and gives the model a stylish look.

The upper system is installed after installation work in the tank, and the bottom reinforcement is arranged before its location on the structure.

The drain valve is much simpler than the water supply unit.

There are no locking mechanisms, as this design does not need it. The drain valve is controlled by traction.

It is a chain or bar.

Previously, when installing a toilet bowl, a lever located on the side or at the top of the cistern was widely used.

Now most models are equipped with a button.

Such a mechanism provides for two modes of draining water. With different intensity of pressing the button, either a complete drain of the tank or half can be performed.

By pressing the lever or button, the damper opens, which closes the upper fitting and the water is drained into the toilet. Then, under the weight of the damper, it returns to its place and the valve closes.

The process of installing a toilet shut-off valve

You can use separate fittings, but it will be better and easier to use branded systems that come with toilets. In this case, exactly all the elements will match.

Materials that will be required to complete the work on the installation of the tank:

Start work on the installation of the tank should be from the base drain device. A rubber gasket is laid between the bottom and the base of the tank. After the tanks are directly placed on the toilet, installing a rubber ring between them, preventing their surfaces from touching each other.

The cistern is screwed to the toilet with bolts.

Here the most important is good anchoring rubber gasket to prevent leaks.

For the upper reinforcement, these elements are not needed, since it is above the water. These nodes are mounted after the installation of the tank.

Installation for one and the other type is basically the same. The tube is pushed through the hole in the tank and twisted on both sides with nuts.

The next step is to connect the flexible hose to the water supply riser, namely to the fitting, and install a tap that allows you to carry out repair work turn off the water in the toilet.

The modern hose is equipped with a nut-grommet clamp, which provides reliable connection. But plumbers usually play it safe and use fuma.

Having brought the tank to the water supply, it will be necessary to adjust the float. The water level should be about fifteen centimeters lower than the edge of the tank.

It consists of installing a water drain mechanism with equipment. Top element inserted through the hole in the lid and secured with a decorative element covering the hole.

Cost of services

Several factors affect the price of toilet cistern replacement services.

Such as the:

the nature of the work and the level of complexity;
additional work.

The cost of dismantling and installing new fittings is from five hundred to eight hundred rubles, and about two thousand rubles will have to be paid for replacing the drain tank.

For the establishment of expensive plumbing, many companies use an additional coefficient. Generally quality work to replace the drain tank and the price are in no way connected. There are a lot of companies and they all work in different price categories.

During the operation of the cistern, problems such as leakage or constant flow of water may occur. The reason may be in the thrust or in the membrane, and they will need to be replaced.

If filling the tank is difficult, then first of all check the connections and the supply hose.

If you do not understand this, then in order to avoid trouble, it is better to seek help from qualified specialists.

The water connection to the toilet tank can be made from below or from the side - this depends both on the design of the toilet bowl itself and on the features of the water supply system. Side connection cistern fittings are easy to maintain and reliable at an affordable price. At the same time, it performs its functions to the full, therefore, when arranging an inexpensive bathroom, it is appropriate to choose it.

Functions of fittings for the tank:

automatic dialing the right amount water;
draining a certain amount of water into the toilet;
overflow protection.

The side connection is easier to connect to the water supply, especially when we are talking about houses of old buildings, in which water sockets are designed for such a connection. In modern universal fittings with lateral inlet, either a stem or a button can play the role of a drain element.

For a comfortable atmosphere in the house, it is necessary that the plumbing work smoothly. At the same time, I would like to note that the sewerage system and the toilet bowl, which are its components, play an important role. In turn, in order for the toilet to work well, you need to pay attention to it. technological features, its design, as well as the condition of the reinforcement.

What types can be

Before deciding how to choose fittings for the toilet, let's try to understand what should be understood by the word "fittings". This word should be understood as all the constituent elements that are aimed at ensuring the operation of plumbing, it includes, including the toilet.

In accordance with the functions performed, several of the following types can be distinguished:

fittings that block the flow of water after the tank is filled;
fittings that ensure the descent of the liquid.

Each of the species constitutes separate mechanisms, which, nevertheless, are closely related to each other. The latter circumstance leads to the fact that if one of them breaks down, the second one also stops working.

How is the tank filled

The function of filling the tank, as already described earlier, is assigned to the mechanism in question. Let's highlight its main details. So, the shut-off system is a combination of shut-off valves, levers, a float and supply fittings.

Several levers usually form a single set of metal or plastic parts connected to the float. For the manufacture of the latter, foam or a hollow plastic cylinder is usually used, it is designed to regulate the water level in the drain tank and determine when the tank will be filled.

In this case, all shutoff valves work as follows. First, the liquid fills the drain tank. In this case, the float rises to a certain limit.

As already described earlier, the float and levers are connected, therefore, when the float reaches a certain limit, the lever acts on a valve specially installed for constipation, the water flow is blocked.

It is also possible to highlight different types fittings according to the location of the liquid supply. So, water, in the presence of fittings for a toilet bowl with a side supply, can flow from the side, while the plumbing is located, as a rule, from above.

With this arrangement, water is usually collected with great noise. The least noise is created by the water supply from below. Also, water can be supplied from above, but this is a rather rare design.

Thus, fittings for a toilet bowl with a bottom connection seem to be the most preferable.

How is draining

Let's consider the principle of operation of the fittings that provide the descent of water. Components such fittings will be:

hole for descent, having a certain angle of inclination;
an overflow tube is required;
the system does not do without a cover for the valve and gum
an important part should also be considered the drain button and the system of mechanisms that ensure its operation.

At the same time, there are several systems that differ in design. So, there is a full drain system with a button; a system that has two modes of draining water, provided with a special function - you can interrupt the descent of the liquid.

In the latter case, an analogue of a key is used, releasing either water completely or partially. As a separate item, I would like to highlight the rod fittings used for the toilet, acting on the basis of the rod.

There are three types of float valves. These are piston operated valves equipped with a special lever. "Croydon" - such a mechanism was used earlier, in modern toilets, usually replaced by another. A valve based on a silicone or rubber membrane that replaces the gasket.

It should be added that if the float fails, the entire locking system will have to be changed completely.

When choosing fittings for the toilet, pay attention to the choice of high-quality, durable plastic parts so that the fittings are resistant to overheating and cooling, withstand mechanical stress.

The diaphragm valve must be selected taking into account the fact that salt-rich water with impurities quickly disables the diaphragm. It is also recommended to choose goods of a good brand in order to exclude the presence of marriage. It is also useful to familiarize yourself with the photo of the fittings for the toilet bowl before buying.

What to do in case of breakdown

If problems arise during the operation of plumbing, then to eliminate them, it is worth adhering to some algorithm. To begin with, find out the causes of the breakdown, adjust the level of water consumption, replace worn parts.

Then you should clean the channels, as well as parts of the system from plaque and dirt. In case of serious damage, you should contact a specialist.
