Stopped My Leak :)

Comments about Watts 3/4" 174A Relief Valve (30lb):

Living in my home for two years. Replaced exact for exact after the old one, age unknown, began leaking. Of course upon removal of the old one, I can see it was quite worn out from many years of service so I am sure the new one will do just fine. Been installed for a few months now and no leaks!!!

  • 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?
    Asked on 11/10/2010 by Pete from NYC

    • CUSTOMER CARE

      A:

      There is no adjustment on this valve. Your pressure reducing valve should be set around 12-25 PSI.
