Every water heater is equipped with a pressure relief valve or sometimes called as an overflow. When pressure and heat builds up inside your water heater, the pressure relief valve opens to let pressure and steam escape. This valve is important for smooth performance of your water heater. This valve prevents heater from bursting in case of excessive heat buildup and pressure. If you are having difficulty with water heater overflows, your Hot water tank expert might take some of the following steps to solve it.
Water is too hot:
If the water coming from your heater is hotter than usual, the heater is not shutting off when it is expected to, the reason could be a faulty thermostat. Pressure and steam are building inside the heater and are not being released by the pressure relief valve. The water temperature must be decreased and the pressure relief valve must be replaced before allowing the hot water tank to reach operating temperature again
Leaks around pressure relief valve:
Leaks around the valve could suggest a number of things, including:
The pressure relief valve is loose
The seal around the threads is broken where the valve fastens into the heater
The main seal has been broken or damaged by sediment or dirt.
If the seal around the threads is creating issues, your hot water tank professional will remove the overflow, coat the threads with a sealant and fasten the valve back in. If the issue is with foreign matter in the main seal, it can be cleared by opening and closing the valve a number of times. If the main seal still leaks, then you will be recommended to replace the valve.
Boiling sounds inside the heater:
A bubbling or boiling sound inside your water heater may show that the unit is overheating and the pressure inside the heater is increasing to a dangerous level. This generally means that the overflow is blocked or stuck. Pressure relief valves that don’t open will have to be replaced.
