Comments about Watts 3/4" 174A Relief Valve (30lb):
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!
Bottom Line Yes, I would recommend this to a friend

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.

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.
