Q: is this pressure valve used on hot water tanks only? Can it be used on Utica furnaces?
Asked by frankie 9 years ago

Verified Reply- SupplyHouse StaffThis relief valve has a 30psi setpoint, which is typical for boilers. As long as the BTU capacity meets or exceeds that of the boiler it should work fine.
Q: My pressure relief valve leak will replace with same will this replacement of a new valve stop the leak
Asked by Boil 10 years ago

Verified Reply- SupplyHouse StaffTypically relief valves will drip or leak when the pressure in the system is nearing, but not reaching the valve set point. If this is the case, the new one would leak as well because there is a problem elsewhere in the system.

Q: how do i know if i need the male or the female Watts m335 pressure relief valve?
Asked by Tim the plumbers son 13 years ago

Verified Reply- PexSupply StaffIt depends on the piping/threading to which you plan to connect the valve. Male connections would be needed to connect to female threads, etc.
supplyhouse used the same picture to describe both the male and female m335m2 relief valve. it is my opinion that the female would appear to have both female inlet and outlet. The picture shows the male which has a male inlet and female outlet. calling the sales rep when you place the order is normal procedure. happy holidays.
