Damage to the water heater is always unpleasant. However, do not be upset and think about buying a new device - perhaps the malfunction is easily fixed, especially if it is a leak.
If a water heater has flowed, first of all it is necessary to localize the problem. There are 3 options:
- Poorly assembled water supply;
- The check valve leaks;
- Flowing from under the tank itself.
If the leak occurs at the junction of the sanitary fittings, try to tighten the problematic joints more tightly with a pair of adjustable wrenches. If this does not help, you need to disassemble the leaking section of the pipeline, and reassemble it, checking the quality of the fitting, not forgetting to use the appropriate sealing material.
Water heater flowed, what should I do? The check valve assembly always uses a non-return valve. This is for two main purposes. Firstly, it prevents the reverse flow of heated water in the direction of the cold riser.
Secondly, the valve protects the tank by relieving excess pressure generated due to expansion of the heated fluid or coming from the line during a period of lack of analysis.
The check valve is a T-shaped fitting that allows water to pass in one direction (from the riser to the drive). If the pressure exceeds the maximum permissible for the heating device (as a rule, it is 6 atmospheres), the spring inside the valve is compressed, opening a drainage hole.
Why is water dripping from the safety valve of the water heater? If the water heater was assembled efficiently, when filling the tank with water, the check valve did not let water pass through, but after heating started and when the tank was working, water gradually oozed through it - this is a normal situation, there is no breakdown in this.
Moreover, in houses with centralized water supply, the flow can increase significantly at night, when water intake is significantly reduced, and the pressure in the system, accordingly, increases. To combat overpressure in the system, it is possible to install a gearbox with a pressure gauge at the inlet of the device to monitor and adjust this parameter during operation.
Attention! If the non-return valve does not discharge the water together due to excess pressure, it is most likely clogged and needs to be cleaned or replaced urgently, otherwise the heater itself may suffer.
Typically, water flowing from a valve through a drainage tube is collected in a storage tank or lowered into a sewer. The volume of liquid discharged per day is 1.5-3% of the size of the storage tank.
If the flow is more intense, the spring inside the fuse may be damaged, the inner gasket has moved away, or it is clogged. In this case, it must be dismantled, disassembled, cleaned and reassembled. If this does not help, replace the valve fitting with a working one.
The most unpleasant if the leak is connected with the boiler itself. If a leak is detected directly from the water heater, immediately turn off the device and shut off the water. After that, you need to remove the outer cover of the device and inspect the leak.
There are two main options for the malfunction: either the tank itself burst, and then the entire unit really needs to be replaced, or because of the valve that did not work out for some reason, due to excessive internal pressure, it squeezed the drive gasket in the area of the heating element mounting.
In this case, you can try to replace this gasket yourself or call the wizard. It is also necessary to check the operation of the valve fuse or replace it.
To avoid such problems, it is necessary to adhere to simple rules during installation and operation:
- High-quality docking of sanitary units using gaskets;
- Connect the device to the water supply system in the correct scheme using a check valve and a reduction gear, as well as a drainage system;
- To control the temperature of heating the water in the tank, do not bring it to the maximum level;
- Turn off the heater if it is not intended to be used for a long time;
You should also use the device in accordance with the operating instructions, carry out routine maintenance.
