Bathroom faucet repair. Bathroom Faucet Repair: A Professional Guide. Types of bath-shower switches
Any bathroom must be equipped with a mixer with a supply of cold and hot water. This device regulates the pressure and temperature of the water flow, and also allows you to direct water to the tap or shower using a special switch. But even the best quality plumbing fixtures can break. Fortunately, in most cases, repairing a bathroom faucet can be done with your own hands. In this article, we will look at the main causes of breakdowns and look at ways to fix a bathroom faucet yourself.
Main types and design of mixers
To find out how to repair a bathroom faucet, you need to understand what type of mechanism this is. And in order to understand the principle of its operation, you need to study the design of a bathroom faucet with a shower in order to carry out the repair correctly. Thus, all bathroom faucets are divided into: valve, lever and sensor.
The design and repair of the valve mechanism is very simple. This device consists of the following elements:
- frame;
- valves for controlling the device;
- spout (gander);
- faucet axleboxes for regulating water supply.
The lever model is more complex, so repairing a regular single-lever bathroom faucet will take a little more time. A typical lever device consists of the following elements:
- frame;
- spout;
- ball or ceramic cartridge for mixing water. A broken ceramic cartridge must be completely replaced;
- nut for fixing the cartridge in the housing;
- handle for controlling the device and adjusting the temperature and pressure of the water flow. Attached to the cartridge lever;
- case cover.
The sensor faucet has the most complex device. The main element of such a mechanism is a photocell that controls the operation of the device. In the event of a breakdown, it is almost impossible to independently restore the photocell, so it is better to entrust the repair of touch-sensitive faucets for a bathroom with a shower to specialists.
If you carefully study how the mechanism of each device works, then repairing a bathroom faucet will not cause much difficulty.
Why the device fails: causes of breakdowns
The process of restoring a faucet with your own hands will be much easier if you know the reason that led to the breakdown of the product. Let us highlight the main ones:
- low quality of products - typical for cheap Chinese counterfeits and products from little-known unscrupulous manufacturers using low-quality consumables and components;
- dirty water in the pipeline;
- the use of outdated consumables on new devices - modern silicone or paronite gaskets are much stronger and more reliable than old-style rubber products;
- a high degree of water hardness provokes cracking of seals and the formation of deposits inside the device;
- mechanical wear of equipment, sensors, cartridges and other consumables.
We will analyze in detail what malfunctions can arise when using a faucet with a shower, as well as how to repair a faucet in a bathroom with your own hands.
Leakage at the junction of the spout and the body
This is the most common breakdown, since the spout constantly moves to the sides, which wears out the round rubber gasket, which is located in the groove of the spout. To replace the rubber gasket, the gooseneck must be disconnected from the body. In this case, the crane repair is carried out as follows:
- unscrew the fastening nut;
- remove the spout;
- remove the old damaged gasket from the spout groove;
- install a new gasket in the groove;
- install the spout into the body;
- wrap 2-3 layers of FUM tape around the thread for the fixing nut;
- tighten the spout securing nut.
After this, the leak at the junction of the body and the gander will disappear.
Leaking from under the control lever
This type of failure is typical for single-lever mechanisms and is caused by cartridge failure. You need to disassemble the device and replace the cartridge. There are several other signs of failure of this part:
- resistance occurs when operating the lever;
- spontaneous change in the temperature of the supplied water flow;
- no supply of cold or hot water;
- The tap does not close or open completely.
Do-it-yourself repair of a single-lever bathroom faucet is carried out in the following order:
- Remove the red and blue plug from the housing.
- Loosen or unscrew the fixing screw using a Phillips screwdriver.
- Remove the lever and unscrew the decorative cover.
- Then, using an adjustable wrench, unscrew the nut that holds the cartridge in the housing.
- Remove the faulty cartridge.
- Place the new part into the housing and reassemble the device in reverse order.
Keep in mind that the protrusions on the cartridge must line up with the indentations in the housing, otherwise the leak will not be eliminated.
Valve leak repair
A two-valve mixer may leak due to mechanical wear or breakage of the sealing washer located on the faucet box. Also, the cause of valve leakage can be wear and tear of the valve axle itself. There is nothing difficult about replacing a washer or axle box.
First, shut off the water in the pipeline, and then perform the following sequential actions:
- remove the leakage valve plug;
- unscrew the screw securing the valve to the body;
- unscrew the valve axle using an open-end or adjustable wrench;
- replace the sealing washer or the valve axle itself;
- Reinstall the repaired or new part, secure with a screw, and install the plug.
Now the two-valve bathtub faucet will not leak!
Fixing a leak in the faucet-shower switch
The shower switch also fails very often. The switch in the bathroom may leak due to a damaged gasket, which is located between it and the body of the product. Repairing the shower switch in the mixer can only be done by disassembling this part:
- holding the rod in a stationary position with pliers, remove the switch button;
- remove the valve with the stem;
- then remove the faulty oil seal from the housing;
- install the new part in place;
- Reassemble the shower switch in reverse order.
The most common failure with spool switches is the failure of the nut that secures the shower switch. Repair of the spool switch occurs as follows:
- Remove the mixer.
- Unscrew the shower hose, switch handle and spool nut.
- Then unscrew the lower switch mounting nut.
- Replace the nut with a new part.
- Use sandpaper to clean the threads and the internal cavity of the nut.
- Lubricate all parts with grease.
- Reassemble and install the mixer in its original place.

Faucet-shower button failure
If after turning off the button does not return to its place, then the reason is a malfunction of its spring. You need to disassemble the switch in the same sequence as described above, and then replace the faulty part.
And if the switching does not occur at all, and water pours out of the tap and shower head at the same time, then the reason is a breakdown of the oil seal, which is located on the switch rod. It is necessary to repair the push-button switch in the following sequence:
- remove the button;
- remove the rod;
- replace the old oil seal with a new one;
- assemble the switch.
Turn on the water and check the operation of the device!
Repair of shower hose and watering can
It is not uncommon for a bathroom faucet with a shower to break down. As a result of wear or destruction of the gaskets, leaks appear at the junction of the shower hose and the body or the hose and the shower head. Accordingly, the repair will consist of replacing the gaskets:
- Unscrew the clamping nut of the shower hose using pliers.
- Remove the old gasket (washer).
- Install a new, better paronite gasket.
- Wind 2-3 layers of FUM tape onto the thread.
- Tighten the clamping nut.
If a leak has formed in the hose itself, then it must be completely replaced.
The water pressure has become weak
If the pressure of the water stream in your bathroom has become weak, but the volume in your neighbors remains the same, then the reason is that the aerator is clogged. This is a special metal or plastic filter in the form of a mesh at the end of the spout. This part saturates the water with oxygen, filters it and prevents strong splashing. Repairing the aerator is very simple and consists of cleaning it.
To return the stream of water to its previous pressure, you must:
- Using pliers, unscrew the aerator.
- Rinse it from rust, salt deposits and small debris.
- Place the mesh in place.
It is better to replace a rusty filter with a new one.
You can fix the bathroom faucet yourself, since DIY repairs are no longer a problem for you. Keep in mind that by using high-quality products and consumables, many such problems can be avoided in the future.
One of the most common problems in the operation of plumbing is the breakdown of the faucet in the bathroom. If you know how to disassemble a shower switch, you can fix the problem yourself and carry out repairs.
Shower switches are classified according to their design and operating principle. By design they are:
In accordance with their design features, the principle of disassembling and repairing mixers changes significantly. We suggest looking at how to disassemble the most common shower switches.
Step-by-step instructions for disassembling a plug switch
The plug switch is also in turn divided into the following subtypes:
- Manual. It switches lek-gander mode only with hand pressure;
- Auto. After a certain time, the plug will return to the closed position;
- Soviet. Here the plug is adjusted by a rotating mechanism. Nowadays this design is very rare.
First you need to turn off the water in the apartment to avoid flooding or other unpleasant surprises during repairs. After this, the decorative panel is removed from the mixer, which indicates the change in temperature during the movement of the mixer handle. There is a threaded connection under the panel. Using a screwdriver, carefully unscrew the bolt and remove the upper part of the handle.

After this, depending on the type of locking mechanism, the sequence of actions may vary:
When working with the Soviet type of cork switch, first the adjusting knob is unscrewed, and then the switch is removed.
Disassembly of a spool-type switch
If the shower switch is installed with a removable spool switch, then the procedure for disassembling it will have a slightly different form:
- From the mixer body you need to unscrew the lower part of the structure - the switch and the hose from the shower. To do this, use an adjustable wrench or a wrench of a suitable diameter;
- To disconnect the hose from the switch, you need to remove the nut that holds the structure. To do this, it is convenient to use an adjustable wrench;
- Afterwards the switch is disconnected from the body. It must be carefully removed from the mixer.
Spool-type shower head switches are also very common, which do not need to be completely disassembled for repair or maintenance work. Simply remove the locking or decorative nut from the switch and carefully pull the mechanism out.
Spool switches are not very popular due to the impossibility of repair. Therefore, if a leak appears on such a mixer, it is easier to immediately change it than to try to repair it.
How to disassemble a shower ball switch
Ball shut-off switches are most often installed in two-valve faucets. A special feature of such devices is that the water pressure and its temperature are regulated by a ball installed in the switch. It is connected to the stem and valves of the faucet. When the handles are rotated, the ball changes its position and sets the required jet pressure, and also switches the shower spout mode.
Step-by-step instructions on how to disassemble the shower ball switch (gander - watering can):
When you assemble the mixer and switch to their original position, it is recommended to screw FUM tape onto all threaded connections, and also replace gaskets and rings. A preventive inspection should be carried out once every six months, this will prevent wear of the seals.
Faucets are rightly considered one of the weakest links in the plumbing system. After all, sooner or later even the most reliable of them begins to leak. And what could be worse for an irritated and tired person than the annoying sound of dripping water? In this case, there is only one correct method of eliminating the problem - repairing the shower mixer. Moreover, you can do this yourself, without waiting for the plumber to arrive. Therefore, any average owner should know how to repair a bathroom faucet. The shower switch is one of the most vulnerable parts of this device.
Main causes of breakdowns
Perhaps one of the most common factors that cause a faucet to fail is the poor quality of the product. The modern market is flooded with sanitary ware made in China and Turkey, which does not have high consumer properties. As a rule, the service life of such products is quite short, and you may soon need them in the bathroom. A shower switch made from low-quality materials will quickly break, therefore, by deciding to save money on its purchase, the buyer is doing himself
The next obvious cause of breakdowns is the use of short-lived consumables. It is not advisable to use rubber gaskets in taps from which there is leakage. In this case, it is better to replace them with ceramic or paronite inserts, which extend the service life of the product. Often problems arise due to incorrect installation of plumbing equipment. Therefore, to avoid the need to frequently repair the mixer switch during the installation process, strictly follow the instructions.
Faucet types
Today there are several varieties of this equipment. Therefore, before starting repairs, it is necessary to understand the structure of the mixer. From a design point of view, thermostatic, single-lever and valve models are considered more convenient. Depending on the type of installation, mixers are divided into built-in and wall-mounted.
Ball mixer design
Most consumers prefer single-lever models. This is due to the high reliability, convenience and ease of operation of such products. To study the structure of the mixer, just look at it in cross-section. So, the single-lever ball model consists of:
- from a decorative plug, on which the symbols of hot and cold water are applied;
- screw;
- control rod;
- a hollow ball with two holes in which water is mixed;
- two rubber seats for passing hot and cold water;
- steam cuff;
- regulating ring;
- ball sleeve;
- aerator.
The most important elements of the mixer are the seats and the ball, which are part of the non-separable cartridge. Therefore, if one of these parts breaks, repairing the mixer yourself usually comes down to simply replacing this module.
Cleaning the aerator
One of the most common problems that most people face is low water pressure. As a rule, this occurs due to clogging of the aerator, which consists of many small meshes. To eliminate this malfunction you do not need to have any specific skills. It is enough to simply rinse the aerator previously unscrewed from the gander thoroughly under strong water pressure, and then screw it into place. If washing does not give the desired results, you can try to carefully remove debris using a thin needle. If this does not bring the expected effect, then you will have to purchase a new aerator.
Bathroom faucet repair: shower switch
The essence of such a breakdown comes down to the fact that water simultaneously enters the spout and the shower net. The main reason for this problem is considered to be wear on the spool gasket located in the switch. To eliminate this problem, it is necessary to replace the gaskets.
However, everything is not as simple as it might seem at first glance. The most important feature is that in some cases, such a breakdown is caused by wear of only one insert. If you are absolutely sure that the reason lies in the top gasket, it can be removed using a thin hook without disassembling the mixer itself. If it is necessary to replace both gaskets, you will have to disconnect the flexible hose and spout. After this, you need to unscrew the adapter and remove the switch handle. The worn rubber rings are removed from the removed spool and replaced with new ones.
Prevention of breakdowns
To avoid the need to periodically repair your bathroom faucet, the shower diverter should undergo preventive measures from time to time. First of all, you need to understand that the worst enemy of modern plumbing is low-quality tap water. Substances and mechanical impurities dissolved in it can damage even the most expensive faucet. To extend the life of an expensive mixer, you need to follow a few simple rules.
Firstly, the possibility of penetration of solid particles contained in water into the working elements of the product should be eliminated. Traditional rubber gaskets installed in conventional faucets are relatively resistant to mechanical damage. But scratches are bound to appear on ceramic discs. To protect the mixing device from premature wear, it is recommended to install self-flushing mechanical cleaning systems.
Secondly, you should try to reduce it as much as possible. Excess carbonates can damage not only plumbing fixtures, but also coffee makers, electric kettles, dishwashers and washing machines. To reduce water hardness, it is recommended to use softener filters. Such devices easily cope with carbonates, which reduce the service life of mixers.
A bathroom in our time is a complex complex of a wide variety of devices, plumbing connections and components. As for faucets, there can be two or three of them - it all depends on how many and what are installed in the bathroom. Any equipment tends to break down sometimes, and mixers are no exception, so you need to know what to do in these cases. Having detailed information and an algorithm of actions, you can easily fix minor faults with your own hands.
Types: design features
Every modern bathroom must have a faucet. Replacing a bath with an invigorating shower significantly saves water consumption. Sometimes the mixer fails, then repair or purchase of new components is required.
The faucet is one of the main devices in the bathroom; it is found in the bathtub, in the shower stall, and in the sink, if it is installed separately. Using this unit, you can regulate both the water pressure and its temperature.
The mixer comes in the following types:
- valve;
- single lever.
The first includes two valves, which, by rotating, allow you to achieve the desired water flow and temperature. The structure of such a unit is simple; if necessary, it can be easily disassembled and repaired. When working, it is important to follow the recommended sequence of operations; this is the best guarantee that there will be no unnecessary parts left after assembly.
Adjusting the water using the second type is that the lever rises upward and turns to the side. Inside this design there is a large ball, which has special slots and is in contact with the lever.
Through such slits, water at different temperatures enters and mixes. The water pressure is regulated by changing the angle of rotation of the lever.
The model with a ceramic cartridge has two plates that contact one another. The plates move relative to each other when the lever changes location. This allows cold and hot water to mix.
The axle box crane is reliably protected by seals, which can be:
- ceramic;
- rubber.
Valve head assemblies can be changed. The axle box crane, in turn, may consist of:
- from tees;
- from the pipes.
A tee connects several pipes; the second type is connected using special wiring.
The lever mixer is very popular, its main advantages:
- ease of operation;
- reliability;
- looks aesthetically attractive;
- ease of installation.
The design of such structures is simple; Unfortunately, it does not seem possible to repair them - the body is designed in such a way that it cannot be disassembled.
Switch Types
Switches from tap to shower can be of the following types:
- cork;
- push-button devices;
- cartridge type.
- spool valves
The most common and simplest are cartridge-type switches. Their main failure is wear of the rubber ring between the housing and the shift lever. The gasket rubber is exposed to an environment where there is both high humidity and mechanical stress. The destruction of the gasket is only a matter of time. Fixing the malfunction is not difficult; to do this, you should disassemble the device and replace the gasket.
What needs to be done to repair the faucet:
- shut off the water supply;
- disconnect the lever from the mixer;
- unscrew the screw from the switch;
- remove the switch;
- install a new ring;
- wrap FUM tape onto the thread in several layers;
- Put the lever in place, tighten the screw.
A common problem with spool switches is that the nut breaks; it secures the switch in the shower itself. Similar incidents occur when the materials from which the mixer is made are made of cheap silumin material.
- brass;
- bronze.
This type of problem can be resolved as follows:
- the mixer is disassembled;
- the hose unscrews from the shower;
- The bottom nut is unscrewed.
If the nut fails due to thread wear, it should be replaced with an analogue made of a higher quality material. After sanding, the device is assembled, lubricated with grease and put in place.
Breakdowns and their causes
Often breakdowns occur at switching points for other reasons:
- button failure;
- the passage of water simultaneously into the tap and shower hose;
- failure of the mechanism that controls the flow of water;
- abrasion of the gaskets in the push-button switch itself.
The leakage can be eliminated by changing the rubber rings. The push-button switch breaks due to the failure of the metal spring, which must be replaced.
If there is a decrease in water pressure in two-valve taps, then it is quite possible that a clogged aerator is to blame; it should be cleaned. It is also possible that the spool valves, which are responsible for the flow of water entering the tap and shower, may fail.
Such units from reputable manufacturers are designed for a long service life, so it is recommended to buy plumbing fixtures on trading platforms that have a good reputation. Each unit of goods must always be accompanied by genuine quality certificates and guarantees.
Trouble-shooting
In order to repair breakdowns, you should use the services of specialists with practical experience. In this case, it is good to have certain ideas about how mixers are designed and what types they come in.
Any mixer consists of several units:
- frame;
- rubber gaskets;
- crane axle box;
- decorative elements;
- valves;
- spool;
- adapter;
- crank.
The most common malfunctions occur in the form of leakage, they are:
- under the gander;
- under the mixer lever;
- under the mixer valve with two valves;
- at the connection points between the hose and the shower.
- Water may leak under the fastening nut due to wear of the gasket.
In this case, the repair can be carried out with your own hands; the qualifications of a plumber are not required.
Often, malfunctions can be easily eliminated by replacing a worn ring with a new partonite ring. When screwing on the gander, be sure to lay FUM tape so that the gaps are better sealed. A leak in a lever faucet occurs when the cartridge itself breaks. This type of problem can be resolved by replacing the cartridge. It can be of different sizes, it depends on the manufacturer. When purchasing a new cartridge, it is advisable to take the failed one with you; their compliance should be 100%.
The leakage from under the lever is eliminated in this way:
- first remove the plug, which is marked with a red and blue marker on the handle;
- the mounting bolt is unscrewed;
- the lever is removed;
- the cartridge is changed;
- the mixer is reassembled.
Leakage in a two-valve design occurs in most cases due to failure of the non-ceramic axle valve; in this case, it is recommended to replace the axle box. It is also common for this type of device to wear out rubber or silicone gaskets. To determine the breakdown, the assembly is disassembled (if it is ceramic).
- the plug is removed from the valve;
- the bolt is unscrewed;
- the plug is removed;
- the valve is unscrewed;
- the axle box crane is dismantled;
- the causes of the malfunction are found.
Repair should be done as follows:
- unscrew the fastening nuts;
- change gaskets;
- the thread is strengthened with FUM tape;
- all elements are reassembled in the same order.
- Problems most often arise with classic two-valve bathtub faucets. They can have a movable spout and be round or flat. Malfunctions occur in most cases due to wear of the gaskets located under the fastening nut. The reason is always the same: too hard water.
Causes of malfunctions of touchless faucets
There is only one reason for this, because this type of mixer is considered the most reliable: there are no components subject to mechanical stress.
Manufacturers provide warranties for these devices for at least five years.
Repairing touchless faucets is never an easy task. Breakdowns in them most often occur due to the failure of the sensors responsible for the flow of water. It is difficult to fix this kind of problem on your own; it would be wiser to delegate this work to a specialist.
There is a high probability that the cause of faucet failure may be too hard water, which contains an excessive amount of iron salts.
The most common breakdowns:
- The water jet is very thin. The simplest fault that can be easily fixed. Most often, this is observed when the aerator fails; this is a special device at the end of the spout. The aerator is usually made of metal or plastic;
- Switching between water supply modes is difficult. In this case, the switching mechanism is repaired.
- Both ceramic and rubber gaskets are suitable for the cores; they can be changed as needed. Silumin is an alloy of two elements: silicon and aluminum. Cheap faucet models are made from this material, which are extremely short-lived due to their fragility. Sometimes you can find spectacular-looking faucets for a low price. Most likely they are made of silumin; it is not recommended to buy them, because it can spontaneously burst or fall apart.
- When purchasing, you should pay attention to the external chrome plating; low-quality products often have poor quality.
- Brass faucets are quality products. It contains copper and zinc. The more copper in the alloy, the more likely it is that the product will last a long time. It is recommended to buy just such devices.
- To properly install the eccentrics, you should rewind them with a flight seal. You will need at least 8 turns of electrical tape (much depends on the thickness and density).
- When tightening the nuts, it is not recommended to overtighten them, so as not to damage the gaskets.
- To check for leaks, it is recommended to turn on the water after tightening the eccentrics. If there are no leaks, then you can continue working.
- Faucets with a turning gander can be mounted at different heights from 15 to 45 cm from the side of the bathtub. The installation must be carried out in such a way that the length of the shower hose is sufficient.
- A flexible hand shower is essential and only the user can select the optimal length.
Tools required:
- electric drill;
- hammer;
- pliers;
- adjustable wrench;
- wire cutters
Phases of work for installing a mixer:
- screwing eccentrics;
- installation of the main building;
- spout installation;
- shower installation;
- testing.
From the above it is clear that installation of the mixer is not difficult. If you strictly follow the proposed instructions, then all the work can be completed in half a day. If you have neither the minimum skills to work with plumbing nor the desire to understand its installation and repair, you can always entrust these tasks to professionals.
To learn how to repair a bathroom faucet with shower, watch the following video:
Every owner, at least once in his life, has encountered a situation where an old faucet has leaked, and purchasing a new device for one reason or another is not yet possible. In this case, he has no choice but to disassemble the faucet in the bathroom and try to repair it on his own.
Let us note right away that in many apartments old two-valve type mixers are still in use, which are increasingly being replaced today by more convenient single-lever models. That is why it makes sense to examine both old and new models of mixers for the design of their valve mechanism. Familiarity with the operating principle of the valves themselves will allow you to take into account in advance all the nuances that are usually encountered when disassembling mechanisms of one or another type.
Design of two-valve mixers
First of all, let's look at the design and operating principle of a classic two-valve mixer.
The old-style mixer is a classic locking mechanism with two valve heads (faucet axle boxes), located in a cast brass body and regulating the supply of cold and hot water, as well as setting the temperature of their mixture. On the back of the housing there are threaded connections used to connect the mixer to the existing water main.
Let us immediately note that the most common types of two-valve mixers are:
- tee-type devices (“herringbone”);
- mixers with separate pipes.
In the first option, the valves for regulating the supply of cold and hot water to the mixer are connected through a special tee. The design of mixers with pipes requires their separate installation.
Disassembling a two-valve mixer
Before disassembling the faucet in the bathroom, you will need to prepare the following tools and accessories:
- screwdriver;
- adjustable wrench;
- a piece of foam rubber or soft fabric.
Disassembling the mixer begins with unscrewing the screw hidden under the decorative valve cover, after which the faucet housing is turned out with an adjustable wrench.
After dismantling the mixer, you can clearly see whether the gasket located on the pusher (rod) of the faucet axle needs to be replaced or whether it just needs to be secured better. After replacing the gasket (tightening the fastening bolt), the crane axle box can be installed in place. Foam rubber is necessary in order not to damage the enamel of the bathroom if valve parts accidentally fall.
Single lever mixer device
The main components of mixers of this type are the following elements:
- device body;
- rotary handle;
- lid;
- mechanical cleaning cartridge (replaceable type);
- gaskets
Various designs of single lever valves can use either ball or ceramic cartridges.
Models with ball-type cartridges are equipped with a hollow ball with holes, which is attached by means of a pin to the tap handle. Through a pair of inlet holes, cold and hot water enters the ball chamber, and after mixing in it, it flows to the outlet of the mixer (to the spout). The water pressure and the temperature of the mixture are set by the angle of rotation of the handle, which affects the degree of alignment of the holes in the associated ball and in the mixer body.
Faucets with ceramic cartridges consist of two ceramic washers that are tightly ground to one another, which move when the handle is moved, and the holes on them are more or less aligned. As a result of this combination, water is mixed and supplied to the spout.
Note! Cartridges equipped with ceramic plates cannot be disassembled and require a complete replacement of the entire mechanism.
Disassembling the mixer
Disassembling a typical single-lever mixer with a cartridge is carried out in the following order:
- Using a screwdriver or knife, remove the blue or red plug located on the lever (handle) of the mixer.
- Then we unscrew the screw located directly under the plugs and which serves to secure the lever to the control rod.
A decrease in pressure is usually associated with a clogged spout and this problem is eliminated as follows:
- The spout mounting nut is loosened and completely unscrewed.
- The filter mesh is removed and then thoroughly washed.
- The nut with the mesh is installed in its original place.
