Pressure relief valve
Product Q&A
4 QuestionsQ: can this valve be mounted either horizontally or vertically ?
Asked by 122JG 8 years ago

Verified Reply- Supplyhouse StaffYes, it can be mounted horizontally or vertically but Watts states "Important: A relief valve functions, in an emergency, by discharging water. Therefore it is essential that a discharge line be piped from the valve in order to carry the overflow to a safe place of disposal. The discharge line must be the same size as the valve outlet, and must pitch downward from the valve." You can refer to Watts website and on their support page under Temperature and Pressure (T&P) relief valves they have instructions and diagrams.
Q: can the 3/4 174a relief valve(30lb.)be installed on any btu/hr. boiler but not to exceed 650,000 btu/hr.?
Asked by reddog 12 years ago
Add your answer
Yes. That 650kBTU limit is just where the boiler size dictates a larger outlet for the Pressure Relief Valve (PRV) connection. In other words, don’t put a reducer on your 1-inch PRV connection just so you can save a few bucks by using a ¾-inch PRV.
Q: my current valve (same as pictured) is still leaking at approx 30 psi. I just changed the expansion tank which I believe was bad (was leaking water out of the schrader valve). Are these valves adjustable so that it will not leak, or should I just replace it? Also, can the problem be the Pressure Reducing Valve?

Verified Reply- PexSupply StaffThere is no adjustment on this valve. Your pressure reducing valve should be set around 12-25 PSI.
This valve is designed to open up at 30# water pressure. NOT adjustable. Look at the feed valve for your problem. If yours is circulated hot water, it should operate at around 20#. Sounds like the feed valve (fresh water supply to system) is charging your system to at or near water line pressure.
Q: IS there a re-build kit available for this valve?
