Fine Product

By Rick

Verified Buyer

Comments about Watts 3/4" 374A Relief Valve (30 psi):

This is a standard 30 psi boiler relief valve. The high quality is what you would expect from a Watts product. There's not really much to say. Usually you replace the old one because it is leaking. Don't test it after installation by operating the handle. Foreign material from the boiler water might prevent a perfect valve seal and it might drip.

      A:

      We recommend that you first ensure the expansion tank is functioning properly. This valve is set to 30 psi. Make sure your system is not over that pressure.
