A savior.
Exactly what was needed to replace a failed pressure relief valve on our boiler. Of course it failed in the cold of winter. Timely delivery and was able to keep my family warm.

Appears well made.
I have never had an occasion to need it. It is a blow-off valve that is actuated when water pressure becomes dangerously high. Since that situation has not occurred (thankfully) I cannot speak to the valve’s effectiveness. I can only say it appears to be well made with brass, stainless steel and a neoprene (?) gasket, and it was reasonably priced.
