How to position the dishwasher drain hose correctly. Correct connection of the dishwasher to the water supply. Some nuances for installing built-in dishwashers

In the event that it is necessary to replace the mixer, then it is better to repair it. At the same time, learn that one of the reasons and the most common problem can be a faulty axlebox tap, and in order to understand the reason for it or not, it is enough to look at whether or not water is dripping from the spout of the tap if it is closed. If yes, then you need to replace the faucet axle box, which you can do yourself without calling a plumber.

Causes, malfunctions of the crane - axleboxes:

If you turn the dial on the faucet and the water continues to drip or the faucet starts to whistle;
The control knobs are difficult to rotate;
Water seeps out from under the flywheel handle.

Kinds

I would like to note that there are two types of axle box crane:

With ceramic cartridges that move up and down to increase or decrease water pressure;
With worm gear (lamb) and rubber seals.

When purchasing this part, keep in mind that the first type is quite capricious.

Crane axle box design

In order to technically competently carry out the work of replacing a ceramic faucet - axle box, you need to become familiar with its structure.

It consists:

From a rod that rotates and a handle is put on it and screwed on with a screw. In the middle of the rod there is a ring that secures the plate, and an adapter is installed below;
From the body into which the rod is inserted all the way and secured with a special washer;
Made of two ceramic plates, one movable and the other not. During operation, they open and shut off the water supply;
Made of a rubber seal that presses the body to the mixer seat;
From an adapter that connects the rod to the top plate made of ceramic.

The worm valve - axle box consists of:

From a rotating rod onto which a handle-flywheel is screwed and secured with a screw;
From the oil seal nut, which is used so that there is no need for frequent lubrication of this part, since you can simply unscrew the nut, fill the oil seal with grease, and rubber gaskets and windings are not needed;
From a housing that is screwed into a faucet or mixer. In the middle of this element there is an oil seal, which is filled with lubricant; gaskets and linen tow are not needed, since the housings of the faucet axlebox and mixer already have a tight fit;
From a shut-off valve that is attached to the stem with a screw or ball (snaps into place). In order for the water supply to stop, it is necessary to lower it, and it will adhere to the mixer seat. And when water is supplied, the valve rises up and water begins to flow from the tap.

When replacing the axle box in a crane, the differences in the design of the ceramic and worm elements are also taken into account.

Design Features

If the part has a rubber seal, then when working, use the thumb to pull out the rod and close the valve with a gasket, which wears out quickly and requires frequent replacement. This happens approximately once every 6 months.

If you need to replace a ceramic valve axlebox, then consider the principle of its operation. In this case, turn the flywheel halfway. In this case, the movable and fixed ceramic plates attached to the rod can move relative to each other, in this case, holes open on them and water begins to flow, and if they are blocked, the water supply stops.

Since ceramic plates hardly change, the service life of this part is quite long. But if they break, then the valve axlebox in the mixer or tap is replaced. Of course, this will require more money than just changing the rubber gasket, although the ceramic part is changed every 7 or 10 years, which is much more convenient.

If the water supply is hard and contains dense particles that negatively affect material such as ceramics, then this type of faucet is not used.

Tools used

To replace the axle box valve yourself with high quality, you will need:

Flat screwdriver;
Adjustable wrench;
Hand drill;
Construction knife.

How to properly replace the faucet axle in the mixer?

As already noted, this part comes in two types, but it has many types, and therefore, if it is necessary to replace it, you must first remove the faulty element. Let's look at how to replace the axle box in the mixer, for this:

The supply of both cold and hot water is shut off at the riser;
Remove the handle. But first you need to dismantle the decorative plug, which is sometimes screwed onto the handle or simply inserted. If the second option, then simply pry it off with a screwdriver or knife and take it out;
The screw located under the plug is unscrewed using a screwdriver;
If you cannot unscrew it, it means that over time it has become stuck or rusted, then a screwdriver will not help and it is better to use a drill. To do this, take a metal drill and drill out the screw head, and only after that remove the flywheel, and then the axle box;
After removing the handle, do not forget that some of them have a so-called skirt that covers the top of the axlebox. This part is unscrewed by hand;
After this, the crane axlebox is dismantled, for which you need to use an adjustable wrench, which must be turned counterclockwise. Loosen the connections and unscrew everything by hand, remove the valve axle;
After that, a similar part is purchased in the store;
When assembling, follow the reverse order and do not tighten the threads on the connections.

It is important! Do all the work by hand, tightening with a wrench. If after completing the assembly there is a leak somewhere, then tighten that connection.

Conclusion

If you notice that even when the tap is closed, water drips or flows from it, and it can also leak from under the flywheel, then the problem is a faulty axlebox, which needs to be completely or partially replaced. How to replace the axle box in a faucet or mixer, and most importantly, how to do it technically competently and independently, without calling a plumber, is discussed in this article. In fact, this is not a difficult job, it will only take 10 minutes.

The axle tap is an integral element of any hot and cold water mixer, which is a water flow regulator. How to change it if necessary? This is what our article is about.

Despite its small size, the faucet axlebox is of paramount importance in the mixer system. Due to the operation of the crane, this regulator inevitably fails, and then the question arises of replacing it, because it is cheaper to do this than to buy a new structure entirely.

In order to replace the faucet axle box in the mixer correctly, you need to know the criteria for choosing a new water flow regulator, otherwise you risk purchasing either a faulty part or the wrong size.

Criteria for choosing a new crane axle box

Before you go to the store for a new faucet element, you need to pay attention to the following facts:

Item type.
Dimensions of the crane axle box.
Type of stock.
Manufacturer of the product.

There are ceramic and worm axle boxes. They are distinguished very simply; to do this, you just need to turn the valve. A product with a ceramic regulator will make only half a revolution, after which it will “stand up,” but with a worm mechanism it will spin three to four times around its axis.

The second thing you need to do is measure the dimensions of the rod and valve, and also find out the size of the axlebox itself. They are now produced in diameters of 1/2 and 3/8. But it’s better to avoid mistakes when measuring and not buy a 1/2 axlebox instead of a 3/8 axlebox, take the old mechanism with you.

Third, when choosing a faucet axle box, make sure that it fits the valve. To do this, immediately before purchasing, try on the axle box to the flywheel. It is also worth taking into account that the securing bolt may have a different thread than in the existing flywheel.

The last thing you need to worry about is the choice of manufacturer. Ceramic and rubber products are part of domestically produced faucets. In imported products, worm-type crane axle boxes are increasingly used.

Note: the rod can be square or slotted.

Removal rules

To ensure that the mixer does not completely fail after repair, it is necessary to follow certain rules for dismantling the failed element. Before starting work, you need to get a screwdriver and an adjustable wrench, but you can get by with ordinary screwdrivers if you have a sufficient set of them.

Before starting dismantling work, it is necessary to turn off the water in the house, both hot and cold. If the apartment has its own tap, then that’s great. It is usually located in the bathroom. But if not, then you will have to turn off the entire entrance, and so that the residents do not become indignant, all work must be carried out quickly.

Note: Make sure the water is turned off by turning the valve all the way.

Then, using a regular screwdriver or even a knife, you need to remove the plastic plug from the valve. A small cavity will open to us, in which a metal bolt will be visible. Unscrew it to remove the flywheel.

After this, access to the rod - the upper part of the axlebox - will open.

To remove the crane axle box from its “socket”, you can use several methods:

Take a wrench and unscrew the element from the mixer. It is necessary to rotate counterclockwise.
If the valve axlebox has a square stem, then you can disassemble the mixer. Firmly grasp the stem and rotate it counterclockwise.

Thus, the shower mixer is disassembled before replacing the faucet axle box with a new element.

Substitution rules

Installation of a new crane axlebox is carried out in the reverse order. It is important that after assembly the mixer does not start to leak, tighten all fasteners. But don't overdo it, otherwise you will turn the axlebox out of the tap, damage the discs or tear the gaskets.

In addition, before installing a new axlebox, it is a good idea to clean the flywheel and threads from accumulated dirt and rust. This can be done using a corrosion solvent, moistening a cloth with it and wiping the threads.

Take note: Fifteen minutes after applying the solvent, go over the threads with a small brush and there will be no trace of rust and dirt left.

After installation is complete, turn on the water and check the work to ensure it is done correctly. The faucet should not leak, and should not be unscrewed when the valve is tightened too tightly.

To prevent replacing the axle box valve from becoming a habit, it is important to do all the work correctly and carefully. If, after changing the element, you do not find any changes for the better, then you should think about the malfunction of the mixer itself, or you chose the wrong product.

The further operation of the mixer depends on the quality of the installed faucet axle. If all the work was carried out correctly, then you will not have to worry about this issue any time soon.

How to repair a crane axle box yourself? The procedure will not seem complicated and tiring if you follow a specific plan and take into account the recommendations of qualified professionals.

In this article you will find instructions for disassembling and replacing this part.

Varieties

Deformations of the crane axle box occur for many reasons. This part of the mixer is used every day, so it is often subject to breakdowns. The design is based on a metal rod and sealed gaskets. The latter are available in rubber or with movable ceramic plates. Based on this, they distinguish ceramic faucet axle and a model with rubber inserts.

Ceramic options are reliable. Allows you to open the water in half a revolution of the mixer handwheel. Options with rubber inserts (also called worm inserts) wear out quickly. To supply water, you need to make several turns of the valve.

Causes of failure of a ceramic crane axle box

Wear of ceramic plates. Occurs rarely and requires replacement of elements. The work is labor-intensive, so it’s easier to purchase a new part.
Foreign objects between the plates. In the future, to prevent such defects from appearing, it is advisable to install a device for purifying water from impurities.
The appearance of a thread between the rod and the valve body. In this case, it is necessary to change the entire part.

Before repairs of any complexity, it is necessary to turn off the water and prepare the tools for work. The minimum set should include a flathead and Phillips screwdriver, pliers, a gas wrench and a spanner.

Preparation for repair

In order to correctly perform operations to restore the functionality of the mixer, everything must be done in stages. The repair plan is as follows:

Remove the flywheel from the crane axle box. To do this, remove the colored decorative plug from the valve. Next, pull the flywheel up. There should be a bolt underneath. Unscrew it and remove the valve.
Clean the threads and flywheel. Run the parts under water a couple of times, use cotton swabs or other similar objects.
Unscrew the decorative insert of the faucet. At this stage, use a socket wrench with a 17mm head.

Advice! In order not to scratch the front surface of the faucet with a gas wrench, it is necessary to make a kind of gasket from thick fabric. But it is best to use a spanner wrench.

How and what to use to unscrew the faucet axle from the mixer? Counterclockwise with an adjustable wrench. The main thing is to hold the mixer. Then clean the threads with a brush.

Gasket repair

Operating procedure:

unscrew the valve axle;
apply a little silicone to the gasket;
install the part back.

Removing foreign particles stuck between the plates

Grains of sand contribute to the leakage of the axlebox and its failure. Foreign objects cause leakage. The order of work in this case is as follows:

unscrew the valve axle and disassemble it;
clean the plates, treat them with waterproof lubricant;
return the part to its place.

Important! The plates must not be turned over.

Elimination of chips formed on the surface of the plates

The best way is to replace the plates.

Reasons for failure of models with rubber inserts

Leaking is a sign that something is wrong with the part. Water leaking from under the flywheel indicates a breakdown of the valve axle.

Gasket wear is the most common cause of failure. The solution to this problem lies in replacing the part. The rubber ring (1 mm) should fit tightly to the metal ring. When making it, you need to take this fact into account.

How to replace the crane axle box?

It is necessary to replace the part in the mixer with an identical one.

To replace, in addition to screwdrivers and keys, you need to arm yourself with pliers - a multifunctional tool that can act as wire cutters, pliers and pliers.

How to remove and disassemble a part?

Turn off the tap using the valve. Pipeline fittings related to shut-off and control products are located in front of the mixer.
Look for a small shut-off valve if there is no valve on the supply pipe. This is a large diameter ball valve in the form of a metal ball with a hole in the top.
If such an element is missing, turn off the water in the riser.
Remove the decorative caps. Use the screwdriver.
Unscrew and remove the screw. It is easy to “calculate”. The part secures the flywheel.
Remove the bushings. They are located at the top of the crane box.
Unscrew the axle box. Apply the key.

Nuances of work

When unscrewing an old faucet axle box, you may encounter some problems. If it is thoroughly stuck to the body and it is not possible to remove it with handy tools, you must apply the following:

Place a pipe wrench around the edges of the bolt. Try to rip it off by moving it from side to side, as if swinging it. Here it is important not to overdo it, namely not to damage the threads and not ultimately break the mixer.
Use chemical-containing products. They will help loosen the threaded connection. Take some vinegar, Cillit-type detergent, or other acid-containing compounds. If they don't help, then try making a small plasticine container around the bolt. After this, pour in the liquid again.
Move the threads using the thermal method. Use a heat gun to warm up the threaded part. It is necessary to achieve complete weakening of the bolt.

If the tried methods do not help, you should remove the valve axle by drilling. To do this, cut off the protruding part of the bolt and drill out the remaining elements. The drill can be replaced with a milling cutter.

Installing a new

Installing a newly purchased or repaired part does not require anything complicated. Perform the same steps as when unscrewing, only in reverse order:

Check if the water is turned off.
Screw in the faucet axle box by hand and only then use a wrench or pliers to be extra sure that it fits snugly to the rest of the structure. You should not put too much pressure on the product, as the gasket may become deformed. Violation of the integrity of the element leads to blocking of the water supply channel.
Be careful not to damage the sealing gasket on the valve seat with the tool.
Tighten the locknut and secure the entire body of the part from turning.
Open the water. The absence of smudges indicates that everything was done correctly.

Water taps are among the devices that tend to leak. But, if repairs are not carried out in time, the precious drops of water escaping from the tap can eventually develop into leaks that will ultimately destroy the faucet.

What types of breakdowns are most common and how to repair a bathtub faucet with your own hands will be discussed in the article.

Half-turn axle-boxes, joysticks and valves are responsible for controlling water flows. And the first place to look for the reason for the leakage of precious liquid is in them.

Failure of these mixer elements can lead to a number of malfunctions of the entire plumbing system. Thus, a valve breakdown can provoke vibration in the pipes, and a violation of the integrity of the half-turn or valve box can cause leakage in the area of the valve itself.

If, due to wear of the plumbing valves, the gander begins to leak, the easiest way to determine the source of the problem is by the temperature of the flowing drops of water

If noise is detected in water pipes, the sequence of disassembling a two-valve structure includes the following steps:

Open each of the valves one by one in order to determine which tap makes sounds when water is supplied.
Shut off the water to the apartment with a shut-off valve.
From the front part of the flywheel, called the wing, remove the decorative plug using an adjustable wrench.
The screw located under the plug is unscrewed with a flat-head screwdriver until the thumb comes off.
The decorative trim placed under the lamb is unscrewed and removed.
After removing the cover, the upper part of the crane axle spindle, equipped with notches in the form of nut edges, will be revealed to the eye.
Having installed a wrench on the edge of the upper part of the spindle, unscrew the core - the valve axle

Further manipulations depend on the type of axle box. Repairing each of the elements that control the flow of water in the mixer has its own characteristics.

Replacing the gasket

A common cause of small leaks in half-turn valves is worn rubber bands on the lower holes or insufficient pressure on the structure with a clamping nut. During operation, they can become flattened and extend beyond the dimensions of the saddle. Therefore, the easiest way to fix the problem is to replace these gaskets.

The rubber gasket located at the bottom of the holes is responsible for regulating the flow of water, but when cracked and abraded, it ceases to cope with the task.

By replacing the gasket, you can get rid of humming and whistling in the pipes. If you don’t have the time or opportunity to purchase a ready-made gasket, you can make it yourself by cutting out a circle with a diameter slightly larger than the size of the valve seat. To make the blank you can use:

a piece of thick leather 2-3 mm thick;
a piece of thick sheet rubber that is resistant to temperature fluctuations.

To replace the rubber gasket, you need to make sure that the water in the tap is completely turned off. Then, using a wrench or adjustable wrench, unscrew the axle box.

After removing the crane box, all that remains is to unscrew the small screw located at the bottom of the structure. Having disconnected the old gasket, a new one is laid in its place, having previously cut a chamfer from the outer edge of the workpiece using scissors at an angle of 45 degrees and a depth of 1-2 mm.

The service life of the sealing gum if the quality of tap water is insufficient is limited to only 1-2 years. Therefore, in the future, this part should be replaced annually for preventive purposes.

After completing the replacement procedure, the screw is screwed into its original place and the structure is assembled, but in the reverse order

Restoring the stuffing box

Replacing the packing is a little more difficult. To do this, unscrew the valve axle half a turn and tighten the oil seal. The master’s task is to tighten the nut with a square cross-section, which is located at the base of the valve box, in a clockwise direction.

The easiest way to seal the packing is by tightening the packing bushing with a wrench or wrench.

When tightening the stuffing box, experienced craftsmen do not recommend using pliers, since they can damage the surface of the bushing faces.

If tightening does not give the desired result, you will have to completely unscrew the seal ring in order to add more packing by winding it around the valve stem. Before unscrewing the stem, it is important to make sure that no water enters the piping. The presence of water risks the fact that it will simply squeeze out the previously installed oil seal and flood the room.

After unscrewing the union nut and removing the bushing, using an awl or the blade of a narrow screwdriver, carefully remove the old stuffing box and replace it with a new one. For stuffing it is allowed to use:

burlap threads;
linen twine;
asbestos cord;
FUM tape.

To increase the water resistance of the twine, it is advisable to impregnate it with drying oil. But it is worth considering that when interacting with hot water, the oil seal will quickly wear out.

FUM tape is laid out in layers in the direction of twisting of the stuffing box tube, carefully compacting each new layer with a screwdriver

When packing the oil seal, it is important not to overdo it so that the bushing can be freely twisted by at least 2-3 threads. The sealed ring is screwed into its original position and carefully tightened.

Repair and replacement of crane axlebox

This element is the main locking mechanism of the mixer. The internal core responsible for the operation of the faucet needs to be replaced if any of two “symptoms” appear:

when constant leaks occur when closed;
when uncharacteristic sounds appear in the form of a grinding sound when turning the mixer.

The sequence of actions when replacing a crane axle box depends on what type of device: with a worm mechanism or a disk version.

Devices with worm gear

Worm-mounted crane axle boxes are equipped with a retractable rod with a rubber cuff. Due to 2-4 turns of the rod, the water supply is completely shut off. Mechanisms of this type are famous for their low price and ease of use. But they have a short service life.

The limited service life is due to loss of smooth operation, which occurs due to a large number of closing/opening valve revolutions

Devices with a worm mechanism must be replaced if cracks or chips are detected on the seat.

Replacing the crane axle box is carried out in several stages:

Remove the top cap from the flywheel. To remove the tap valve, unscrew the bolt located under the flywheel cap. If this process causes difficulty, use pliers.
With a little effort, unscrew the valve. The threads and inner surface of the flywheel are cleaned from operational debris accumulated in the cavity.
Using sliding pliers, the “hardened” faucet fittings are unscrewed, opening access to the core installed in the mixer.
Carefully remove the axle box. To ensure a tight fit of the new core, thereby preventing liquid leakage, the mixing thread is cleaned before deepening the valve axle. Using a card brush, the flywheel base and the nose of the gander are also cleaned.
After making sure that the new axle box is compatible with the threaded connection, screw the new element into place of the removed one.
Reassemble the tap in the reverse order.

To prevent damage to the glossy surface, before fixing the instrument, it is recommended to build a layer by placing a thick piece of fabric under it.

When screwing in a new axle box, to seal the thread, it is necessary to wind it in several layers using FUM tape

When installing an inexpensive mixer model, it is advisable to check at the installation stage that there is a sufficient amount of lubricant. If necessary, the seals should be lubricated with silicone or any other waterproof lubricant.

Disc-type crane axle boxes

The main working unit of the crane axleboxes, made of ceramics, are two tightly pressed plates with symmetrical holes. When displaced at the moment the handle is turned, they block the flow of water.

Faucet boxes made of ceramics most often become unusable due to interaction with water, which contains various types of impurities.

Ceramic faucet axle boxes are famous for their long service life, but less resistance to contaminated water. The main reason for their failure is the entry of foreign objects into the interplate space.

If the integrity of the ceramic inserts responsible for controlling water flows is damaged, they cannot be repaired. In this case, the defect can be eliminated only by completely replacing the old core with a new one.

The technology for disassembling a disk structure is not much different from that used for worm mechanisms. It includes five main stages:

Using a screwdriver, lift the top plastic valve cover.
Unscrew the fixing screw.
Remove the flywheel.
Remove the upper part of the axlebox from the saddle.
By separating the upper and lower parts, you gain access to the ceramic discs.

When installing a new ceramic core, it is important to control the degree of tension. The easiest way to ensure that the faucet axle is tightly screwed and pressed into the mixer is by installing a lock nut.

In the future, in order to prevent damage to the disk core, experts recommend installing coarse filters at the apartment entrance. They will protect ceramic elements from the harmful effects of water impurities.

Video tip: how to repair a disc crane axle:

Replacing the single lever faucet cartridge

When dealing with a single-lever joystick-type mixer, in which a polymer or ceramic cartridge is responsible for controlling water flows, troubleshooting will require replacing the unit.

The single-lever design is equipped with a cartridge, inside of which there is a ball surrounded by rubber cuffs with holes that ensure mixing of water flows. And the most common cause of failure of such devices is worn cuffs that require replacement.

There is a cold/hot water indicator on the handle of the single-lever faucet on the front side, which acts as a plug

To replace the cartridge, the first step is to make sure that the water supply to the faucet is shut off. Then release the remaining fluid from the system by lifting the lever to do this.

Using a hexagon, unscrew the screw holding the joystick under the handle by one to one and a half turns. Having completely unscrewed the switch handle, remove the joystick by turning it to the right or left. And together with it, the decorative cap located below is unscrewed.

Under the decorative cover there is a nut that holds the cartridge. It can also be unscrewed using a wrench.

The technician’s task is to remove the cartridge and carefully clean the seat from deposits with a napkin, and then install a new cartridge on the prepared base.

Along with removing the cartridge, the rubber seals are also removed, which are subsequently replaced with new ones. The design with a new mechanism is restored by assembly.

The cost of a cartridge equipped with disk plates is not high. Therefore, replacing this element will not significantly affect the family budget.

Mixer switch repair

Shower switches also often fail. And problems manifest themselves in the form of too tight movement or leakage of fluid in the closed position of the mechanism. There are two types of mixers. The former are already equipped with built-in switches of the “shower-spout” type, while the latter, referred to as “moon,” are collapsible structures.

“Luna” faucets are independent collapsible structures responsible for switching the water flow between spout and shower

Collapsible “moon” structures are subject to repair. Shower-spout devices equipped with built-in switches cannot be repaired if they break down. The only way out is to make a complete replacement.

The technology for repairing such switches on a mixer includes the same steps as when troubleshooting a crane axle box. But it is worth considering that switches can be equipped with one of two types of mechanisms:

rod - equipped with a push-button spring-loaded rod that moves the valve, redirecting the movement of water from the gander to the shower;
ball - structurally similar to the device of a disk crane-axlebox and allows the switch handle to make a full turn.

Ball mechanisms have an almost unlimited resource. Their only drawback is sensitivity to large suspensions. Even an attempt to close a switch jammed by scale can cause a breakdown.

Rod devices are convenient due to the minimal actuation force, but due to liming of the valve rubber they have a short service life

Owners who have installed faucets that have a rod diverter as a switch most often encounter a problem in which the device stops locking the shower when the water is turned off. And the key reason for the breakdown of such structures is the failure of the disk-type core installed inside, the replacement technology for which is described in detail above.

If the role of the switch is performed by a ball mechanism, when repairing the structure, you can get by with small “sacrifices”

When repairing a shower mixer ball valve, disassembly and repair work is performed in the following sequence:

Remove the front cover-plug of the shift handle and unscrew the screw.
After unscrewing the sleeve, carefully remove the handle. Depending on the design, it can be obtained separately or connected to a ball plug.
The removed ball is inspected for dirt or rust. If one is found, it is thoroughly cleaned.
Disconnect the shower hose, remove the top trim and clean the internal cavity of the body. When cleaning, special attention should be paid to the plastic conical seats for installing the ball.
The cleaned parts are assembled into a single structure.

If, when disassembling the mixer, the ball remains inside, you should first remove the gooseneck and then unscrew the bottom cover. This work should be done as carefully as possible so as not to damage the thread.

Shower Switch Repair Video Guide:

Repairing other minor damage

Switches with a push-button mechanism often “sin” in that, with low water pressure, they spontaneously return to their original position. And this problem is associated with an excessively tight return spring.

Removing one or two turns of the return spring will help eliminate the problem of the button spontaneously returning when the water pressure is low.

If the opposite situation occurs, in which the button does not return to its original position when the water is turned off, the cause is excessive sealing of the rod. Loosening the gland nut or applying silicone grease under the rubber ring will help correct the situation.

The reason why the button does not return from the “shower” position to the “spout” position may also be the loss of elasticity of the spring. In this case, it is better to replace the part with a new one. But if there is no possibility, to return the spring to its elastic properties, use a proven method:

Stretch the spring well.
In this position, heat it at high temperature.
Quickly cool the hot workpiece by immersing it in a container of cold water.

If the cause of water leaking from the tap is lime deposits on the seat and rubber, chemical cleaning will help correct the situation. For these purposes, you can use Domestos, Belizna or any other household chemicals that can cope with lime.

If water from the tap begins to flow poorly, then before repairing the faucet, make sure that the mesh covering the neck is cleaned

If the quality of tap water is poor, the mesh may become clogged with dirt. In this case, you just need to carefully remove it from the neck, and then clean it with a brush under water pressure and put it back in its original place.

There is nothing difficult about repairing a bathtub faucet. The main thing to remember is that any minor repairs to plumbing fixtures installed in the house require strict adherence to the disassembly rules.
