Plumbing malfunction is becoming a fairly popular problem in everyday life. And the question of how to fix the toilet with your own hands becomes as relevant as possible. But in order to solve it, you need to know the causes of the malfunction, their features and how to eliminate it. Most of the faults are in the toilet cistern, and they must be considered especially carefully.
How the toilet cistern works and what it consists of
Directly the very work of this element is based on the principle of operation of the hydraulic seal, but it consists of:
- Leverage systems.
The very principle of the mechanism is as follows:
- A button is pressed, which opens the hole at the bottom of the tank.
- Water under pressure is poured into a bowl, from there into the sewer.
- After closing the hole, the channel opens, through special hoses, water is drawn into the barrel through it.
- Together with the water level, the float rises, which, reaching a certain height relative to the bottom, blocks the water supply jam.
The cover must be removed to access the system. In some cases, it simply lies on the tank, sometimes it is screwed to it, being fixed with a button. Thus, to access the inside, you must unscrew the flush button and remove the cover.
It is worth noting that the lid is made only in a set with the tank, and you cannot find it separately on sale, so remove it carefully so as not to break it.
The designs themselves are different, and may differ in appearance, but it is worth noting that the principle of operation is the same in each.
Most common faults
Now let's look at the most common problems, and then how to solve them. Among the problems are:
- Water leakage from the barrel into the toilet.
- Malfunction of the water supply valve, and therefore the constant filling of the barrel.
- Failure of the flush button.
- Bowl leak.
- The button is stuck, which necessitates repeated pressing to drain.
- High noise level when filling the cistern.
In any case, it is quite easy to carry out repairs, the main thing is to know the cause, and how to fix it. Let's consider the solution to each individual problem.
Eliminating tank leakage
If your toilet is constantly leaking odor, this indicates a leak in the cistern, which in most cases means displacement or skewing of the float lever, which causes damage. For a complete study of the problem, it is enough to examine it.
- We take out the float and carefully examine it.
- In case of damage, pour out the accumulated water, and seal up the damaged area.
We attach the float back.
Repairing damage in an element is quite simple, for which a sealant is used, or simply melted plastic. But note that this will only be a temporary elimination of the problem, which will return after a short period of time.
Replacing the siphon membrane
In cases where water continuously flows into the bowl, or you have to repeatedly press the drain button to wash it off, this indicates a failure of the membrane, respectively, it must be replaced. This is done as follows:
- We install the crossbar in place of the tank lid.
- We tie the float lever to it.
- We completely drain the water from the tank (due to fixing the float, a new one will not be recruited).
- Disconnect and take out the siphon.
- Next, you need to remove the old membrane and put a new one.
Subsequently, to collect, we perform all actions in the reverse order.
Failure of the flush button
This usually happens when the traction breaks down. To fix the problem, you need to buy a new element and connect it, or simply make it yourself from a piece of wire, righting it in such a way that when you press the button, it pulls the valve and opens the tank flap.
A rather unpleasant problem can be the constant noise of the tank when drawing water. This problem is especially troublesome at night. To eliminate it, you can build a homemade muffler, which is done as follows:
- From the inside of the tank, we connect it to the hose to the inlet to the float valve.
- We lower the other end vertically to the bottom.
Thus, noise must be eliminated. If this solution does not help, then you can try to adjust the water flow. In some cases, it may be necessary to completely replace the drain mechanism.
Replacing the flush mechanism of the toilet bowl
Almost all problems with the tank can be solved by replacing the drain mechanism.
To do this, you need the following tools:
- Rubber and plastic gaskets.
- Pipe wrench.
- New drainage and locking-float mechanisms.
The replacement process itself is performed as follows:
- First you need to shut off the water supply.
- Then you should disconnect the hose through which the water is supplied.
- We take out the locking-float mechanism.
- The next step is to unscrew the tank mount.
- We remove the cistern.
- Do not forget the sealing gum that seals the junction of the tank with the bowl.
- Next, unscrew the plastic fastening of the drain mechanism from the bottom.
- We remove the old drain.
- We take a new drain mechanism, put a gasket on it and install it in place of the old one.
- We securely fix its mount.
- We put a new gasket in place of the old one and install the tank.
- We tighten the fasteners. It should be noted that the contact between the metal of the bolts and the ceramics is not allowed.
- Plastic spacers should be used.
- We install a new locking mechanism, also using new gaskets.
- We connect the water supply hose. Its threads can be additionally sealed with silicone.
- Next, you need to adjust the degree of filling the tank. This is done by changing the height of the float.
- We close the tank with a lid and install the button.
We resume the water supply.
This method is the most reliable in terms of DIY toilet repair. But with many malfunctions, it is enough to replace individual parts, or even just change the gaskets. Sometimes it is enough to correct a skewed check valve or float.
If a piece of ceramics just broke off, you can glue it. It is better to use glue from UHU, Bison, Tamiya, but ordinary universal glue like "Moment" will do. If the integrity of the bowl is broken and water is leaking, a new one should be installed.
It should be said right away that the breakage of the bowl is quite a rare occurrence. For the most part, malfunctions occur as a result of improper fixation of plumbing. Correct installation and timely repair can help to avoid problems with it.
The most common problem is bowl leakage, which can be caused by:
- Poor pear fit
- Saddle damage.
- Poor nut tightness.
- Float valve not adjusted.
To eliminate each of the problems, it is enough to replace the problem parts, which are located mainly in the tank.
Seat cover repair
There are many varieties of toilet seats, and even with different additions, such as heating or self-cleaning. One of these functions is a microlift, which is present today on almost all comfortable covers (except for the most budgetary ones).
It is a rather complex mechanism that slowly and without noise lowers the toilet lid on its own, for which it is enough to lightly pull it.
Of course, such a mechanism can also fail. Most of the problems can be in the spring or nuts. It is quite easy to replace the nuts, but the selection of the spring is quite difficult, since finding a suitable one is not an easy task. To do this, you will already need to contact a specialized center, and if a suitable part is not found, you will have to replace the entire cover.
As you can see, repairing the toilet is quite simple, and it's not difficult to do it yourself. We invite you to see visually how the replacement of certain components is carried out. We also recommend that you familiarize yourself with the material on installing the toilet, if you suddenly have to replace your own.
