Review on 🔥 WATTS SB1156F Pressure Relief Boiler by Vince Preston

Exactly what it claims to be. The bass/bronze case is what I wanted compared to the iron cases at my local home center. Fast, easy installation. The pressure is said to be factory set at 15psi, which I thought was close, but I do a cold start so my hot temp is close to 20psi after a few heat/cool cycles. This isn't a problem with the valve, but if you want to maintain a lower pressure you may need to adjust it to 20% to compensate for temperature changes.
