DIY plumbing repair in the house: Instructions

DIY plumbing repair in the house: Instructions Life hacks in the work of plumbers - repair of a leak in a toilet bowl, pipes and a ball valve. How often it happens that something has broken down in the house and the help of a plumber is urgently needed. But sometimes all the craftsmen are busy, or there is no extra money to pay for repairs, and the problem is such that it cannot be postponed "for later". What to do? Here are some helpful tips from plumbers to help you deal with the problem, even if you're a beginner.

Let's look at the 3 most common problems.

Leaking toilet

The flush function assumes that water will flow into the toilet bowl in order to clean it of waste products. The process starts from the moment you press the button, which is built into the tank and ends when you press the lever again. With this action, you control the drain valve. It is connected with a locking mechanism, which, after draining, opens the way for a new portion of water to enter through the cold water supply system. If, for some reason, after flushing, or even constantly flows in a thin stream, then it is time to check the tank fittings, since some of the parts are out of order.

But before you start repairing a toilet leak, you should understand whether something is really wrong or it seemed to you.

The following factors can serve as signs that the drain is not functioning properly:

  • DIY plumbing repair in the house: Instructions Constant or intermittent sound of water bubbling.
  • Limestone and rusty streaks at the water outlet.
  • The inner wall of the toilet is constantly damp.
  • Weak and prolonged flushing process - only a salvo discharge can be considered normal.

  • The appearance of condensate on the tank and pipes, which was not there before.

The last sign indicates that cold water is constantly moving through the pipe, and under normal conditions the water is not constantly used and before the descent has time to warm up to room temperature.

In some cases, the cause of the leak is due to dirt that accumulates at the bottom of the water tank. In this case, it will be sufficient to thoroughly clean the inside of the tank. To do this, drain and immediately shut off the water, remove the fittings and wash with cleaning agents and a brush, so that no sediment remains on the bottom and walls.

If such "cleaning" did not help to solve the problem, then we proceed to the next stage - familiarization with the design of the drain mechanism.

Tank device

There are several types of fittings that can be called typical, and among them there is an outdated type of drain with a pear, which is assembled according to a primitive scheme and is suitable for tanks with side connections. This phenomenon is rare and not typical for modern models. Let's turn to more modern models of tanks, which consist of a float and drain module.So that you had to repair the toilet leak with your own hands as rarely as possible, the float on a thick metal wire was modified and turned into a more complex structure, which is capable of blocking the water supply not from the side, but from below.

In this case, the position of the float can be adjusted to dispense a portion of the drained water. Due to the similarity of the valve models, it is easy to replace the design or replace individual parts - a float or drain mechanism, a drain lever.

First, shut off the water supply and empty the tank. All parts can be unscrewed manually or with a set of keys. There are practically no metal parts, and only plastic elements are used together.

They are strong enough, will not be deformed when exposed to hard water, will not rust and are easy to clean with household chemicals. Since a leak can appear for various reasons, we will consider several of the most popular options.

The float mechanism has failed

If the float has ceased to perform its functions, then it will not rise to the desired level and will be constantly in one place. The reason is that, most likely, the float has lost its tightness and began to sink. There is still a chance that the mounts have broken.

To do this, you need to take an old float, and then buy a new one and install it.

The rubber seal has become unusable

The sealing ring made of rubber or polymer is the weakest point in the mechanism. It is located at the outlet of the water stream, therefore, at the same time it can be a barrier that retains sediment / dirt, due to which the gum quickly wears out and frays. If it is just dirty, clean it and put it back, check it works. If the problem is leakage, replace the element.

Leaking toilet after flushing

Sometimes the following happens - flushing has occurred, but after a while the water is still flows down the toilet. After everything stops, but only when the tank is filled to the maximum. Although the losses seem to be small, the toilet bowl will slowly and surely begin to coat.

There are several reasons for this:

  • Defective parts in the valve.
  • Displacement of the drain column.

  • Partial blockage in the drainage area.
  • Small parts of one of the valves have broken.

To find out what the problem is, visual diagnostics should be carried out, and if necessary, dismantle the drain mechanism or the float valve. The skew will be noticeable immediately - the water drain button will start to jam. To fix the problem, remove the roof and inspect why the column has lost its previous stability.

If it slides out of the socket and changes position a little, then just put the valve in place.

Preventive measures

To prevent leakage in the toilet, the repair of which is not the most pleasant, did not appear, monitor the condition of the tank fittings and carry out the following preventive measures:

  • Cleaning all parts and internal surfaces from red plaque, mineral deposits and silt substances.
  • Regularly check the condition of the sealing elements, parts and fasteners that are the riser at the joints.
  • Adjust the valve correctly.

Now let's move on to the next type of repair work.

Repair of pipes

DIY plumbing repair in the house: Instructions The longitudinal strength of pipes of metal-plastic type is quite high, therefore, in the installed (stationary ) condition, there are very few factors that can lead to a violation of the integrity of the material. Most often, similar problems can appear at joints that have very little longitudinal stability compared to the base of the pipe.

Usually, the main types of metal-plastic type water supply faults are:

  • Leakage of fittings.
  • Cracks in the metal body.
  • Cracked fitting.

The most common problem in the functioning of pipes made of metal and plastic is precisely the last reason - leakage of fittings. Systematic use and the vibrations that arise as a result of this can lead to the fact that the waterproofing properties deteriorate in the transition areas of the system. The pipes begin to rub in, the nut fasteners weaken, and the rubber gaskets lose their elasticity. Such changes will remain unnoticed for a long time until the fitting begins to leak.

Cracks in a metal-plastic pipe can cause leaks.

Because of this, the permissible bending angle of the material increases, the aluminum body of the product is deformed. At first, everything can be completely invisible, since the polyethylene sheet will not lose its integrity. But after some time, in places of cracks due to pressure in the system, the plastic will delaminate and a leak will form. Another problem that has become extremely popular is the formation of holes in the fittings. There can also be many reasons for the formation, ranging from the fact that the material is of poor quality, ending with the fact that everything is due to thermal overloads.

Do-it-yourself pipe leak elimination

What to do if there are leaks? You can neutralize pipe damage with your own hands and not resort to the help of a master. Performing repairs on your own will make it possible not only to save money, but also to restore the functionality of the water supply system in a short time.

Depending on the type of damage, there are several solutions to the problem:

  • Leakage of fittings. To get rid of the leak, take a wrench and slightly tighten the joints that are loose.As a rule, half a turn is enough to eliminate a leak.

    In general, the nut should be tightened until it is completely secured. But do not overdo it, as over-tensioning can crack the fitting body.

  • Cracks in the case. To repair a reinforced-plastic pipe, the crack should be repaired using a conventional bandage. The principle of such a device is that you put a small rubber gasket on the pipe and then fix it.

    In the role of a bandage, you can use a flap of dense rubber, part of a car or bicycle tire. The fixing of the holding gasket will be carried out in 4 places using special clamps or by winding ordinary wire.

  • Cracked fittings. To eliminate such faults, it is required to use a complete disassembly of the system and replace the damaged element. Other solutions to this particular problem will not be effective and will not be able to fully neutralize the leak.

The described options are the most effective and are used to eliminate leaks in the metal-plastic type water supply system. Moreover, performing such actions will not be difficult and will make it possible to neutralize leaks with your own hands in a few minutes.

Features of the repair of the pipeline installed on press fittings and compression fittings

Two types are used in the construction of metal-plastic systems fitting connections:

  • Compression.
  • Press fittings.

The principle of operation of the first type of element is that a special nut should be screwed in place of the threaded connection, which ensures full fixation of the clamping ring.

This type of connection is the simplest, since it does not require special tools. At the same time, it is not the most reliable, so it is necessary to have constant quality control. Working with these fittings is as easy as installation.

Troubleshooting requires:

  1. Locate where the integrity of the system is compromised.
  2. Cut off the water.

  3. Loosen the clamping nut.
  4. Give back the fixing ring.
  5. Disconnect the pipe from the adapter.
  6. If necessary, cut a part of the pipe a little, clean the hole and tighten the ring.
  7. Put the ring on the pipe, insert everything back into the groove and screw on the nut.

The sequence of actions is simple and does not require you to put in a lot of effort. Troubleshooting a press fitting is much more difficult. This connection is much more reliable, provides high quality fastening and does not require constant monitoring. But to assemble a similar system, special crimping pliers are required, without which it will not be possible to create a full-fledged pipeline.

The following tools are required for elimination:

  • Wrench.

  • Roulette.
  • Special pipe cutter or hacksaw for metal.
  • Pencil.
  • Pliers.
  • Press fitting crimping pliers.

The presence of such tools will make it possible to carry out a full-fledged replacement for leaking parts of the pipeline with your own hands. Moreover, the repair will not take much time, and the system will function after half an hour.

Repair of the ball valve

If the valve suddenly leaks, then what to do in a similar situation? Let's consider. Shut-off ball valves became widespread during the installation of an intra-apartment or intra-house water supply system. No matter how reliable the crane is, sometimes situations arise when you need to repair the product yourself.

Short description

DIY plumbing repair in the house: Instructions The device is very different from standard valves in design, but repairing a ball valve with your own hands is not difficult.

This requires a minimum amount of knowledge:

  • Many people still believe that in cranes it is necessary to replace polymer gaskets in case of any breakdown and after that everything starts working.
  • There are actually gaskets in the ball valve, but there may be other problems.

It consists of two parts - inside the mixer or faucet there is a shut-off device, which looks like a metal ball with special holes for water outlet. As the ball turns, the head decreases or increases.

So, let's look at the possible malfunctions and the solution to each of them.

Possible malfunctions and methods of solving the problem

The crane will not be subject to repair if it has visible damage in the form of cracks on the surface housing. A similar defect often comes across on cranes, which are of poor quality, the cheapest, and are made of poor materials. First, check if the pressure has decreased due to the drop in water pressure in the system. To do this, you will need to open other taps in the house and see how much pressure is in them.

Another reason is the clogging of the aerator at the outlet channel, and then it simply needs to be removed and cleaned. If there is a rusty stream of water coming from the tap, then look for the cause in the water supply system, not in the device.

Also, the following breakdown of the ball valve is most common, when water flows from the mixer, the water pressure is weak and it is not possible to properly adjust the water temperature in the mixer. Water may start to leak due to clogging of the space between the rubber gasket in the cartridge and the turning elements. Even small grains of sand can lead to the fact that the tightness of the structure will be broken.

For this reason, you will need to disassemble the mixer and clean it, otherwise the leakage will increase due to the deformation of the rubber gasket, which will require replacement of the element.

Weak head may be due to clogged shutter.In order to avoid such a malfunction, it will be necessary to install a coarse filter in front of the mixer at the entrance to the house. Temperature changes in the water will cause one of the ball holes to clog with sand or pieces of rubber gasket.

If the cause is still not found, then you will need to completely replace the faucet on the riser with water.

The reason for this may be the desire to save money on the purchase of a quality mixer or tap.

Such devices are usually made from silumin - an inexpensive material that has low strength and often begins to crumble due to any mechanical influences. For this reason, it is better to buy quality devices than to repair cheap items.

For work you need the following tools and materials:

  • Pliers.
  • Wrenches.

  • Special grease.
  • Screwdriver.
  • Rubber gaskets.

Please note that hot and cold water should be shut off before disassembling the mixer. The screw that will hold the pivot arm of the mixer should be removed, applied with some effort and slightly moved to the side.

Also, do not forget about the water supply hoses, which may deform when the device is turned.

A defective ball valve should be repaired carefully, and also carefully inspect all parts and details. Take special care to remove foreign matter in the cell and rubber gaskets. After assembly is complete, check everything for leaks and test.
