Water Heater Pressure Relief Valve Replacement Tips
A water heater pressure relief valve is an important safety device on a water heater that works to limit the pressure and temperature for tank water heaters. Identifying and fixing any problem with the relief valve quickly and efficiently will ensure that you maintain the safety of your hot water system. Here are some tips to keep in mind when replacing your water heater pressure relief valve.
Tip 1 - Buy a Quality Valve
Buy a valve that is certified from ANSI and ASME to ensure that it will be properly sized and fit correctly with your water heater.
Tip 2 - Capacity Exceeds Input
When selecting a new pressure relief valve, it is important that the BTU capacity of the valve be greater than the BTU input of your water heater. Ensure the capacity is correct before installing a new pressure relief valve.
Tip 3 - Position Valve Downward
When you are installing a pressure relief valve, it is very important that the valve is pointed downward and that tubing is installed to discharge any excess water. The drainage pipe should be connected to a drain and should not come in contact with anything using an electrical current.
