Works as designed

Comments about Watts M335M1, 3/4" Male Pressure Relief Valve:

It's a boiler safety pressure valve - and it works. Every time these little home furnaces get drained down, the safety valve will lift before all of the air is out and the system 'balanced' - and this time there was as usual - and this lifted at about the correct overpressure.

Works for a Weil McClain CGA Boiler

By Yosemite Sam

from Trinidad, CA

Verified Buyer

Comments about Watts M335M1, 3/4" Male Pressure Relief Valve:

Good price, great service. Got it to replace a Watts M330-M1 (375,000 BTU rated) relief valve that was original on a Weil McClain CGA Gold propane fired boiler. This one is rated at 510,000 BTU so I just assumed it would work fine (wouldn't have used one with a BTU rating smaller than the original). Fairly easy to install since my drain line is CPVC. The price on this valve was about 2 times less (including shipping!) than the local plumbing supply house wanted. It's even cheaper than buying the original Watts M330-M1 from PEX! Only reason I rated it 4 stars and not 5 is because it hasn't been in long enough to know if it will last as long as the original (which wasn't more than 4 years).
