Polypropylene valve repair

Each house or apartment has a plumbing supplying cold and hot water, as well as a heating system consisting of pipes and radiators. To repair or replace individual sections of pipelines, the liquid must be shut off, which is done using a valve. It is recommended to constantly monitor the condition of the device and, if necessary, promptly repair the valve. Otherwise, in emergency circumstances, you can flood not only your apartment, but also the premises located below.

Repair of polypropylene pipes. What to do if it suddenly leaks

Polypropylene is classified as a hard material that is resistant to abrasion and high temperatures. They are not afraid of any corrosion, therefore they are not exposed to stray currents. The material is recognized as environmentally friendly due to the presence of polyolefins. Any technical process will be characterized by safety and compliance with all necessary standards. But sometimes you have to repair these pipes yourself.

Polypropylene pipes are characterized by rigidity, strength, and thermal conductivity, which explains the lack of thermal insulation. Due to the material used, the installation is considered safe and of high quality at the level of the European standard. The product significantly extends the service life of the structure, which is why construction engineers often recommend choosing PPK polypropylene.

Repair work is only necessary after a long period of use. Plumbing structures function as distribution mechanisms in buildings of various types and purposes. The pipes are suitable for cold and hot water supply, heated floors, and central heating systems. This possibility became a reality due to its resistance to heat exceeding 100 degrees.

Signs of leaking pipes

Instant installation and minimal weight of pipes with the convenience of carrying out a modernized system and repairing pipes are the main advantages of PPR pipes. If the joint is installed poorly, it leads to depressurization with the appearance of mechanical damage to the product.

Leaks are characterized by obvious signs:

the appearance of moisture on pipes due to small leaks;
reduction in water pressure when a damaged area occurs;
severe damage is characterized by serious progression;
decreased blood pressure;
reduction in pressure.

Do-it-yourself repair of polypropylene pipes involves solving problems with leaks and depressurization of pipes. Non-pressure systems provide for the installation of systems at joints using a socket method. Obtaining a seal is possible using rubber seals at the joints.

Pressure structures suffer from breakdowns, so to extend their service life it is recommended to use the services of a trusted professional. The connection of the joints requires welding. Obtaining a solder joint is possible, but the process requires dry pipes or certain elements thereof.

Replacing the faucet gasket or its core

First you need to turn off the water. In our case, the core responsible for starting hot water needs to be replaced, so we only turned it off. Then you can start disassembling the valve. To do this, you need to get to the screw with which the valve is screwed to the core. To do this we needed to unscrew the small cap (required large pliers). In your case, everything may be even simpler; the red or blue cap is pryed off with a stationery knife and removed. It all depends on the type of valve.

So, we got to the screw. Now you need to unscrew it. Old screws are very difficult to unscrew, so we used a screwdriver. But usually you can get by with an ordinary flathead screwdriver.

By unscrewing the screw, you can easily remove the valve. Now that same core will appear in front of you. This is where the problem almost always lies when a faucet leaks or a valve turns.

Now this entire part needs to be unscrewed from the mixer. To do this, use pliers, a wrench or a gas wrench to turn the core counterclockwise. In old cases, the first movements may be difficult. But then the part can be unscrewed even with your fingers.

Methods for eliminating leaks

When welding PPR pipes, the diameter is taken into account. This affects the choice of socket or socket welding. The connection is made using a coupling, and butt and threaded assemblies are made with fittings with a socket. If the pipe diameter is more than 63 mm, then butt welding is used. The connection is made with special equipment.

Socket soldering is performed with a welding machine if the diameter does not reach 40 mm, and if it exceeds, centering devices are selected. After degreasing, they proceed to the welding process. Soldering is responsible for reliability and high-quality connection.

To ensure that the sections are clearly attached, it is important to cut correctly, so use sharpened scissors. When installing heating systems, it is important to clean the edges of the product. Any repair by soldering is considered a relevant method for connecting components. The process can easily be done independently. They do not allow the structure to leak and give strength and durability.

Ways to solve shower problems

Sometimes troubles happen with the shower hose and watering can, more often due to wear of individual elements or poor water quality.

Poor water supply through the shower screen

Typically, water does not pass through the mesh very well if the holes in the mesh are clogged. Here, after removing the mesh, it is easy to clean it with an ordinary awl or needle.

One of the main enemies of faucets and shower heads is lime, which is found in large quantities in tap water. You can only get rid of it using a fine filter.

After screwing the mesh back, the water supply and direction of the streams are restored. Both the plastic panel with holes and the remaining parts of the shower and faucet can be wiped with a vinegar solution to remove plaque and stains.

Leaking shower hose and drain

If the leak appears due to wear of the internal part or winding, there is no point in repairing the hose; it is easier to buy a new one. Its cost is low, and the service life of new modifications is much longer.

During the replacement process, the mixer handle is moved to the position for supplying water to the spout, then with light movements I unscrew the old hose and fix the new one

If both the drain and the shower are leaking at the same time, the problem is a loose joint between the plug and the body. To correct the situation, first remove the locking screw. The next step is to tighten the union nut. This reduces leakage, but switching water from the drain to the shower is a bit difficult.

To completely eliminate the leak, you need to grind the plug onto the mixer body using special grinding pastes. They are sold in many stores.

We also recommend reading our article about other common faucet failures in a bathroom with a shower.

Is it possible to fix pipes without a soldering iron?

If dismantling is impossible and the damaged area is too large, then it is removed. Welding is not always applicable, so to repair polypropylene pipes with your own hands, you must follow the following methods:

Clamp with a clamp. In this case, the water is not completely turned off. A reliable layer of material completely eliminates leakage due to its water resistance function.
Repairing leaks using cold welding.
Material patch. The tapes are first dipped into two-component glue and the pipes are wrapped. Not applicable for high pressure systems.
Sealant tape. Temporarily stops leakage and can be applied in layers.
Using sealant as a temporary measure to eliminate the problem.

A leak forms at the most unnecessary moment. Therefore, it is important to pay attention to the main reasons for their occurrence. With prolonged use, corrosion may occur. Even a small leak indicates that the polypropylene pipe needs to be repaired. Solving the problem on your own will not bring the desired result, so it is recommended to use the services of professionals.

How to seal plumbing products

This question worries many novice craftsmen. There are several types of seals available; errors not only cause leaks, but can also completely damage the equipment.

What types of sealants are there and what do professional plumbers recommend?

Flax with sealing paste

The photo shows a strand of flax and a tube of paste

A traditional seal, but rarely used lately. Previously, oil paint was used instead of sealing paste. Remember that sealing paste has almost no effect on the quality of sealing, it only prevents the flax from rotting. This means that connections must be tightened with considerable force, and most modern plumbing equipment is made of silumin, a very weak alloy.

It is necessary to wind a flax flagellum onto the thread, recessing it into the turns of the thread, trying to ensure that the flax fibers are smeared in the paste

Result of thread sealing

Conclusion - such connections can only be used on durable steel fittings, because tightness is ensured not by lubrication, but by tightening force.

Another disadvantage of flax is that it cannot be completely covered with threads, and this worsens the appearance of the water fittings. And the last problem is that after using the sealing paste you must constantly dry your hands, otherwise unsightly stains will remain on the surface of the plastic pipes. For professionals, this is a significant loss of working time.

Paste is visible at the junction

FUM tape

A universal seal, used in most cases for internal installation of water supply and plumbing. To seal, there is no need to exert increased effort, which minimizes the risk of cracks forming on weak elements.

FUM tape

When purchasing, check the quality of the FUM tape; it should stretch a little and not tear.

FUM tape is available in convenient packaging, making it easy to use

The tape has two disadvantages - relatively high cost and the inability to adjust the position of the connection. If it becomes necessary to adjust the position of the connected elements by unscrewing, then you will have to completely disassemble them and make a new seal, taking into account the mistakes made.

How to wind ribbon correctly

Even a slight unscrewing back causes leaks. But for home use, this is the optimal sealant with an unlimited shelf life. To connect several fittings you will need a couple of meters of tape, and a skein has ten meters. One skein will last for several years.

Sealing thread

In terms of its properties, there are many similarities with FUM tape. But it has one important advantage - manufacturers guarantee that when unscrewed back 180°, the threaded connection does not lose its original tightness. Although professional plumbers do not recommend unscrewing more than 90°, this ability makes using threads very convenient. Especially for those craftsmen who find it difficult to determine the correct position of the fittings by eye the first time. The cost of threads largely depends on the manufacturers, but it is always higher than that of tape.

The process of winding the seal does not require special skills

Anaerobic sealant

The most modern material, completely unknown to many non-professionals. Anaerobic sealants can be dismantled or difficult to dismantle. The former do not create much inconvenience during repair work. The latter must be heated before dismantling, and this can be quite difficult. Recommended for use in hard-to-reach places that make it difficult to tighten threaded connections with wrenches.

Anaerobic gel sealants

Advantages - the ability to adjust the position of the fittings; when unscrewing, the tightness is completely preserved. There are two disadvantages: high cost and the thread must be perfectly clean. Due to these features, anaerobic sealants are most often used during the installation of new plumbing systems and during the connection of new plumbing equipment. The high price pays off due to the significant acceleration of installation work.

Application of anaerobic sealant

All seals, when used correctly, provide 100% sealing. Find out the types of bathtubs and their sizes by following the link.

Valve repair.

Hello dear subscribers and guests of the blog. In this article we will look at how to repair a water valve.

Previously, I wrote an article “How to shut off the water yourself,” in which I briefly discussed the issue of repairing the valve yourself if it is impossible to turn off the water supply. After some time, I noticed that people often came to this article from search engines using the queries: “how to fix a faucet”, “turned off the faucet and water flowed”, “the valve doesn’t hold, what should I do” and the like, but the essence came down to one thing — the average person doesn’t know how a valve or faucet works, doesn’t know whether it’s possible to restore the functionality of this important element of the water supply system, and when he came to my blog, he couldn’t find an answer to his question.

Preparation and necessary tools

The first rule of any plumbing repair is to turn off the water supply. Valves can usually be found in the toilet; the levers simply need to be turned 90 degrees. If the equipment has not been used for a long time, the valves may become blocked. It doesn't take any heroic effort to turn them. This way, you can simply rip off the tap and then instead of one problem you will have to solve two

Valves should be developed carefully, gradually increasing the effort and adding lubricant drop by drop.

Only after the water supply is securely shut off can repair work begin. First you need to prepare the necessary tools so that they are at hand:

adjustable wrench;
flat screwdriver;
crosshead screwdriver
wrench, etc.

Usually this simple set is quite enough. Auxiliary elements will not interfere, for example, pieces of rubber or leather for making new gaskets, fluoroplastic sealing tape, which replaces liners, rags, sponges, detergent to remove dirt accumulated inside the mixer, etc.

Advice. To prevent an accidentally dropped tool from damaging the sink or bathtub, it doesn’t hurt to put something soft underneath: a rag, a piece of foam rubber or other material suitable as a shock absorber.

The reasons why a faucet is leaking can be very different. For a traditional two-valve faucet, the most pressing problem is the wear of the gasket or liner, which needs to be replaced. If a ball (or hinge) valve, which is designed fundamentally differently, is leaking, completely different actions will be needed.

The faucet is leaking due to wear on the mixer

If your efforts were in vain and the faucet continues to dribble or hum, you need to check your work. Unscrew the tap and get to the gasket; it is quite possible that it burst, was initially of poor quality, or was installed crookedly. If this is not the case, the cause of the leak is wear and tear on the mixer. After serving for a certain time, modern plumbing equipment becomes unusable (such is the quality these days), and therefore you will have to spend more money than on a simple gasket and choose a new faucet for the bathroom.

Try to bring it as close as possible to the old one in terms of parameters so that the installation goes without problems, but choose a high-quality mixer so that you don’t have to bother with it in the future. Installing the mixer is very simple, and we have already mentioned it on our website.

Valve malfunctions (polypropylene water valve)

Repairing a water valve begins with determining the cause of its failure. Most often, the valve requires intervention from specialists in the following cases:

complete absence or wear of rubber gaskets
presence of a piece of scale inside
scratches and pores have formed on the surface of the polypropylene valve
rod bent

The final cost of valve repair work is determined by the technician at the site after identifying the cause of their failure. Yudu performers work without intermediaries, which allows them to offer their services at low prices.

Video description

The video shows how to change the gasket.
If the mixer with a ball lock is broken, you should remove the lever (joystick, handle). To do this, you need to find a fastening bolt on its surface, which can be hidden with a decorative plug. Next, unscrew the screw and remove all parts of the mixer to remove the ball from it for inspection. If there is damage or defects on the surface of the lock, it should be replaced.

It is also necessary to inspect all seals for wear and contamination. If there is no damage, but the leak appears due to a blockage, then you need to carefully clean all parts from sand, debris or limestone deposits. The latter can be easily removed using chemical agents, for example, “Santi”.

Before installing all parts in place, it is recommended to apply a special waterproof lubricant to them. After completing the installation of the mixer elements, you can check the tightness of the connections.

If there is a breakdown inside a device with a cartridge, the entire unit most often needs to be replaced, but first you need to remove it. To do this, you need to find a plug on the mixer handle, remove it and unscrew the fastening bolt. Then you need to unscrew the nut that holds the cartridge with a wrench.

This is what the cartridge looks like in a mixer Source superdom.ua

This is necessary in order to remove the mechanism and inspect it for wear or damage. If the gasket in the cartridge is damaged, it can be replaced without replacing the entire unit. You should also pay attention to the inside of the ceramic plates, since if a solid element (iron or regular sand, limestone or something else) got between them, then when the joystick moves, such debris could rub the grooves, which is why the faucet leaks.

If the faucet is new, all the seals are intact, but a leak still appears, then this may be a common manufacturing defect. A new faucet may leak due to defects or damage that occurred prior to installation. In this case, it is recommended to replace the faucet from the seller or contact a service center.

Breakdowns that require repair work

Valve repair is necessary in the following cases:

the mechanism does not keep the water flow in the closed position
water seeps through threads
When the valve is open, noise and hum are heard

Thread breakage due to careless handling of the mechanism is the most common damage. Difficult turning of the handle will also indicate a malfunction and the need for servicing of the mechanism. But the worst case of water valve failure is ingrowth. In such cases, it is necessary to carry out welding work or cut down the locking mechanism along with part of the pipe.
