How do you use a pressure relief valve?
In operation, the pressure relief valve remains normally closed until pressures upstream reaches the desired set pressure. The valve will crack open when the set pressure is reached, and continue to open further, allowing more flow as over pressure increases.
Can pressure relief valve drain into pan?
The terminal end of the pipe shall not be threaded. Discharge from a relief valve into a water heater pan shall be prohibited.
What PSI should an expansion tank be set at?
The recommended water pressure is between 50 and 60 PSI. Thermal Expansion Tanks contain an air bladder which is pressurized with air, and expands and contracts to absorb the expanded water from the water heater. needed.
