Relief Valve
PLUMBERS, will you please advise if I need a PRESSURE RELIEF valve in addition to the T & P on the wtr heater?
I have purchased a REPLACEMENT bladder tank for my residential well, and the instruction sheet says I should install a pressure relief valve. The EXISTING system does not have a separate one, except for the T & P valve on the water heater.
Insofar as the water heater shares the same pressures in the system, is this one valve all that is required?
The new tank is rated for a 125 psi working pressure maximum, and I intend to use the system with a 40 – 60 psi pressure switch.
The T & P relief on the water heater has a tag showing 150 psi.
Your help will be appreciated.
T and P stands for Temperature and pressure.
Pressure relief is covered unless your area has some odd requirements but this is primarily protection for your water heater and that circuit.
My well in Houston had an air bleeder valve on the tank but my pump would never have gotten up to those pressures and yours probably wont either.
The law requires that all pressure tanks be rated but relief valves are seldom a requirement on well pump systems.
Good Luck!
