Water Heater Safety Valve Leakage

For water heaters, the safety valve is very important, because it is related to the safety of the equipment and people, but some valves always leak, and how to repair them are not good, why in the end? Here's the reason for the leak:

Scenario 1. Leakage occurs when not in use:

1. When the electric water heater is not heated, the leakage may be due to the fact that the cold water pressure in the water heater is greater than the jump pressure of the valve. This phenomenon is more significant when the water pressure in the municipal water network is relatively high during the low peak period of midnight water use.

2. To solve this problem, we can install a pressure relief valve on the water pipe to reduce the pressure of tap water from high pressure to a suitable pressure, so as to ensure that the water pressure at home will not be overpressure, but also can play a good water-saving effect.

3. The cause of leakage is the failure and damage. At this time, we need to replace another one.

Circumstances 2. Leakage of water heater caused by improper sealing of inner liner:

1. Usually in the process of using the water heater, the button seam of its right cover will condense water beads in a very low place, which will rust the inner gallbladder of the water heater and lead to leakage of the inner gallbladder.

2. Open the right end of the water heater to check when the power is cut off safely. If a large amount of condensed water, yellowing of the biliary orifice and dripping water has been found, the phenomenon is that the water heater leaks due to improper sealing of the biliary orifice in the water heater, and the heating pipe of the heater needs to be removed for maintenance.

Situation 3. Leakage occurs when the electric water heater is heated and no one uses hot water.

1. Under such circumstances, it is normal to encounter the leakage of the safety valve of the electric water heater. After the hot water heater is heated, no one uses the hot water.

2. The electric water heater is equivalent to a closed system. When the water in the water heater is heated, its temperature will rise and the volume will increase continuously, and the volume of the water heater is certain.

3. Where there is no excess expansive water absorbed, the water pressure will continue to rise. When the pressure is greater than the take-off pressure, it will take-off and relieve pressure to protect the inner liner of the water heater. Then we will find the leakage.

Circumstances 4. Safety valve orifice outlet water:

1. When the water heater is in use, when the tap water pressure is too high, it will cause the steam pressure in the water heater to be greater than the pressure relief. At this time, there will be a small amount of effluent. The temperature controller will be damaged, and the water heater will always be in the state of heating.

2. When solving the problem, the pressure relief valve can be installed in front of the water heater inlet or the outlet can be opened.

Water heater safety valve leakage usually has the above four methods, we must be careful when choosing in the market, remember to check repeatedly, after installation also need to be debugged, these problems do not exist, we will use more safely.
