Comments about 3/4" x 1" Boiler Pressure Relief Valve (45 psi)
My Laars Mascot boiler came with a 30PSI relief valve, which I changed with this 45PSI recently. It was apparent that on cold days when the boiler had to put out more heat, the pressure built up in the system to just around 30PSI. This caused the relief valve to continually discharge water from the system, to the tune of a 5-Gal bucket every few hours. Since the pressure was no where near being out of the range of normal operation, it became apparent that the 30PSI was completely inadequate for this system. Price is high due to uncommon pressure setting.
