Great product at a great price
By Tony from Tabor
from Tabor City N.C.
Comments about Watts 3/4" 174A Relief Valve (30lb):
There is not a lot to say about a relief valve other than is meets requirements or it does not and it works or it does not in this case it does work and it meets the requirements . In this case this valve is just what we needed and it was at a great price.
Bottom Line Yes, I would recommend this to a friend

Works well until spring wears out
from Cincinnati, OH
I've noticed that the spring on this product will wear out and it'll start passing water at 25psi, then 20, then 15, etc. The part looks well made and works fine when new but I wish it would last longer than 2 years.
from Tacoma, WA
Replacing 20-year-old valve which had begun to fail. This was the perfect fix for my hydronic system and far better price--even with shipping--than I could find locally. Thanks!
Works as it should
By Dan S.
from Ridgewood, NJ
Exact replacement for a leaking pressure relief valve on my Weil McLain boiler. Original was over 20 years old! I replaced my expansion tank durring the same service with a recommendation from a professional. Glad I did as I determined my expansion tank had a slow leak as well. Replaced in the summer so bleeding system was much easier. Suggest a comprehensive boiler check BEFORE heating season.
Pressure Relief Valve
from Bend Oregon
Have a boiler furnace for heating the home, the pressure relief valve started to leak continuously, needed replacing, so I ordered a new one from Pex. It arrived quickly, installed the same day, and everything works as it should.
