Downstream cistern fittings. Toilet flush cistern fittings: how the flush device works and works Flush fittings for flush cisterns instruction

The first task after installing the toilet in place and connecting it to the sewage system is to install the tank fittings. From the correct installation and quality regulation of this plumbing equipment the smooth operation of the entire system will depend. Armature cistern is a device that ensures its filling 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.

The device of the drain tank fittings

The toilet cistern assembly consists of the following components:

  • an angled drain hole;
  • an overflow tube installed on the side of the drain hole;
  • valve covers with elastic band;
  • tank filling mechanism;
  • drain button mechanism.

Before setting up the toilet fittings, let's look at its main components.

Tank filling mechanism

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

  • float device;
  • stop valve.

A float, attached to a metal or plastic arm, moves up or down when the water level in the reservoir 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 water supply system. When the water is drained, the float is lowered, the lever opens the access of water from the pipe to the toilet tank.

Water drainage mechanism (flush mechanism)

The flush mechanism is designed to allow water from the tank to enter directly into the toilet. Components of the escapement mechanism:

  • drain siphon;
  • release lever (handle).

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

Installing and configuring fittings

After installing the toilet in the designated place and then connecting the toilet to the sewage system, the next step is to install the cistern fittings: the video, offered as a short instruction, will help to carry out this work correctly.

Installation of toilet cistern fittings

Consider the technology for installing toilet cistern fittings:

  1. Place a rubber gasket on the drain mechanism.
  2. Install the mechanism in the tank, screw it with a plastic nut.
  3. Put plastic or iron (depending on the configuration) washers and rubber gaskets on the fastening bolts. Insert the bolts into the holes. On the other side, put on a plastic washer and tighten the nut.
  4. Slide a rubber O-ring onto the plastic nut. If a new ring is used, no sealing is required. If a previously used ring was used, all connections should be carefully lubricated with a sealant.

Pro tip: A close inspection of all structural details may reveal minor casting defects. In this case, you will also need to use a sealant. Place of installation o-ring you also need to coat it with a layer of sealant, having previously cleaned it.

  1. Place the cistern on the toilet seat and secure it with nuts.
  2. Secure the filling mechanism. Attach the hose from the water pipe.
  3. Replace the tank cap. Screw on the drain button.

Pro tip: Do not additionally wind anything on the thread of the mounted mechanism for draining water when putting on the hose. Try not to skew so as not to rip the threads and ruin the part.

Valve adjustment

Installing a toilet and cistern should not be too difficult. But in some cases you may need additional customization toilet fittings. So, to adjust the height of the drain valve:

  1. Disconnect the draft from the overflow pipe.
  2. Squeeze out the glass latch.
  3. Move up or down the rack.

The water level in the barrel is adjusted as follows:

  1. 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.
  2. Install the overflow pipe above the maximum water level by 20 mm and below top level racks 70 mm.

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

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

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

Everyone knows the sound of water pouring 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, repairing a toilet is most often the repair or replacement of broken cistern fittings. This procedure is simple and will not take you much time.

How does the flush cistern work? In fact, there are two independent devices installed in it - this is a filler 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, flush). The combination of these two devices forms the valve for the toilet cistern. Various manufacturers offer their models with some unique designs, different forms and colors. Despite such a variety, it is important to understand that almost all of them are universal (the probability that a universal fittings purchased in a store will suit you is about 95%). That is, knowing your type, you can easily buy the fittings you need in any plumbing store. In the framework of this article, fittings for built-in cisterns are absolutely not considered. The fact is that they just do not fall into the above 95% of the 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 fittings for the cistern

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

  1. Filling valve type:
    • with side inlet - 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 bottom inlet - the valve is mounted on the bottom wall of the tank. In this case, the eyeliner is connected from below.
  2. Column type:
    • with a button - for flushing, you must press the button on the tank lid;
    • with a stem - for flushing, the stem twitches upward with decorative element at the end.

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

  1. Single flush - one button. When pressed, all the water contained in the tank is drained.
  2. With dual flush - for such a column, the button is divided into two parts. Pressing one flushes using only half of the water contained in the tank, the other causes a complete flush.

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

A hole with a larger diameter was made under the button fittings in the tank lid than under the rod. Therefore, in most cases, you will not be able to replace a column of one type with a column of another.

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

We should also dwell on the old-style fittings. Now there are still many cisterns that are installed on a toilet with such fittings, or cisterns that are 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 side) and a side fill 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 to either repair and adjust the fittings for the tank so that water does not pass through, and this is very difficult to achieve, or just buy a toilet with a modern tank, which is more preferable, especially if you have a water meter installed.

To summarize, we will illustrate all types of fittings:

Filling valves. Left to right: bottom feed, side feed, old style

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

How to choose fittings for the tank

Now let's move from theory to practice. When the question arises of buying a new valve for the flush cistern, there is a completely natural desire to save some money. It often leads to some typical errors:

  1. Despite the fact that the fittings are universal, their designs are from different manufacturers can be very different. Therefore, it is wrong to try to find only one broken part. Most likely, you will not succeed, and you will only waste your time. The conclusion is to buy only the whole. As a last resort, bring the entire fitting (column or valve) with you to the store. There is a small chance that such a spare part will be found, for example, from defective fittings.
  2. It is wrong to look for fittings for your specific tank, that is, exactly what it was. It is here that it is important to remember that they are universal, which means that knowing your type, with a high probability any universal the right type will suit you.

This raises the question of how to determine the type of your fittings?

To determine the type of filler valve, just look at your tank, namely, where the flexible water supply hose is connected to it. If it is 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 bottom feed. Look under the tank and see for yourself.

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

Determine the type of your fittings and choose your appropriate name (one of the above) - this is what you will need to inform the seller upon purchase.

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 wide enough - from 150 rubles. up to several thousand. In order to choose a quality one and not overpay at the same time, you should pay attention to several nuances:

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

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

So, the fittings have been purchased, it remains to mount them.

Replacement of fittings

Replacement of fittings begins with dismantling 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 filler valve does not require this. In any case, you must first dismantle the old elements. Let's consider this process in full step by step on specific example... Let's take the following toilet as a test sample:

It can be seen that his armature is one-button with a bottom feed. Any other replacement procedure, including a rod one, for example, with a side feed, 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, you need 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 tank lid. In this case, the cover will be removed without dismantling it. Then just go to the second step. For rod fittings - we turn off the decorative knob on the rod and unscrew the cover that covers the hole in the tank through which the rod passes (of course, if it was screwed on).

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

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

and take out:

Will remain inside Bottom part columns. On the sides of it, you can see the caps of the bolts that attach the cistern to the toilet.

4. Unscrew the fastening nuts under the tank. This can usually be done with just your hand.

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

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

A sealing gasket remained at the landing site:

6. Dismantling the tank in our case could be done without first disconnecting the supply line. If it is necessary to change the filler valve, then we perform this operation now.

Flexible hoses can be rolled and turned by hand. The key is used only if absolutely necessary.

7. Unscrew the column mounting nut:

and valve nut:

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

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

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

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

The fittings of the toilet cistern are a kind of "filling, which ensures the work of collecting, retaining and draining 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.

Mostly modern models toilets are equipped with plastic fittings. It is quite durable, does not undergo corrosive processes and negative effects. chemical substances present in the water.


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

By design, shut-off valves can be separate and combined.


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

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

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

The advantage of shut-off valves is that in the event of a breakdown, you can replace or repair only the damaged unit, and not change the entire system.

This affects the family budget and facilitates assembly and disassembly work. Therefore, the use of such systems is still relevant today.


Elite class presents latest models products in which valves in a new design are used. In it general system connects drain and fill valves.

Setting up this type of reinforcement is quite complicated. But with correct installation guarantees safe and flawless operation of the unit.

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

The shut-off 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 resistance to moisture and 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 toilet valves


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

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


Differences in installation have fittings with upper and lower water supply. Both systems involve closing 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 has a dependence on the water level of the drain barrel.


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

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 They are mainly equipped with shut-off valves with a lower water supply. This design is quieter, more comfortable and gives the model a stylish look.

The upper system is installed after installation works in the tank, and the lower fittings are arranged before it is located on the structure.


The drain valve is much simpler than the water supply.

There are no locking mechanisms here, since this design does not need this. The drain valve is controlled by a rod.

It is a chain or barbell.

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


Most models are now equipped with a button.

This mechanism provides for two modes of water drainage. At different intensities of pressing the button, either a complete drain of the tank or half of the tank can be performed.

By pressing the lever or button, the flap is opened, 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 toilet valves

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

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



The installation of the tank should be started from the base drain device... A rubber gasket is placed between the bottom and base of the tank. After the cisterns, it is directly placed on the toilet, placing a rubber ring between them, preventing contact of their surfaces with each other.

Screwing the cistern to the toilet is done with bolts.

The most important thing here is good anchorage rubber gasket to prevent leaks.


For the upper reinforcement, these elements are not needed, since it is located above the water. These assemblies are also mounted after the tank has been installed.

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

The next step is to connect a flexible hose to the riser of the water supply system, namely to the fitting, and install a tap that allows renovation works turn off the water in the toilet.

The modern hose is equipped with a nut-washer clamp, which provides reliable connection... But plumbers are usually reinsured and take advantage of the 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.

The installation of the water drainage mechanism by the equipment is concluded. Top element inserted through the hole in the lid and secured with a decorative element that covers the hole.

Service cost

Several factors influence the price of toilet cistern valve replacement services.

Such as:

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

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


For the installation of expensive plumbing, many firms use an additional coefficient. Generally quality work on the replacement of the cistern and the price are in no way connected. There are a lot of firms and all work in different price categories.

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


If it is difficult to fill the tank, then you must first 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 bowl can be made from the bottom or from the side - it depends both on the design of the toilet itself and on the features of the water supply system. The fittings for the cistern with side connection are easy to maintain and reliable, and their price is at an affordable level. At the same time, it performs its functions in full, therefore, when arranging an inexpensive bathroom, it is appropriate to choose it.

Functions of the cistern fittings:

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

It is easier to connect the side inlet to the water supply system, especially when it comes about old buildings in which the water sockets are designed for just such a connection. In modern universal valves with a lateral supply, both the stem and the button can play the role of the drain element.

For a comfortable atmosphere in the house, it is necessary for the plumbing to work properly. At the same time, I would like to note that the sewerage system and the toilet, which are its constituent parts, 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 state of the armature.

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 work of plumbing, it includes, among other things, a toilet.

In accordance with the functions performed, there are several of the following types:

  • fittings that shut off the flow of water after the tank is filled;
  • fittings that provide fluid release.

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 stops working too.


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 set of shut-off valves, levers, float and supply fittings.

Several levers usually make up 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 is full.

In this case, all shut-off valves work as follows. The liquid first fills the drain tank. In this case, the float rises to a certain limit.

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

You can also highlight different types fittings according to the location of the fluid supply. So, water, in the presence of fittings for a toilet bowl with a side connection, can flow from the side, while the water supply is usually located on top.

With this arrangement, water is usually drawn with a lot of 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, the most preferable is the fittings for the toilet bowl with a bottom piping.

How is the drain carried out

Let us consider the principle of operation of valves that provide water drainage. The constituent parts such fittings will be:

  • a hole for a descent having a certain angle of inclination;
  • an overflow tube is required;
  • the system is not complete without a valve cover and elastic band
  • 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 complete drain system with a button; a system that has two modes of water drainage, provided with a special function - you can interrupt the drainage of the liquid.


In the latter case, an analogue of a key is used that releases either water completely or partially. A separate item 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-based valves equipped with a special lever. "Croydon" - such a mechanism was used earlier, in modern toilets is usually replaced by another. The valve is 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 valve is resistant to overheating and cooling, withstand mechanical stress.

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


What to do in case of a breakdown

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

Then you should clean the channels, as well as system parts from plaque and dirt. In the event of a serious breakdown, consult a specialist.
