A:  No, if it leaks all the time it is defective or the pressure in the system is higher than the valves rating. Mike

Q:Can this valve reset if it goes off due to higher pressure? e.g. if it 'leaks' water since water pressure is high, will it stop leaking if the pressure goes back below threshold? Also, will it go off again if the pressure increases?
by|Nov 25, 2021
1 Answer
Answer This Question

A:  Yes, the valve resets. It will stop leaking once pressure normalizes.

    It works
    The first one ordered was defective. This one was the replacement. On the first unit, the retainer ring for the adjustment o-ring was not staked properly and loose allowing o-ring to push out. The second unit had the same fault but I was able to re-stake the retainer. Valve functions fine now. Be aware that there seems to be a quality control issue here.
