Review on 🔒 Pressure Female Thread Maximum Gauge by Dean Love

I installed a new pressure control valve on the main supply line to the house. Before the relief valve was installed, the room pressure on this gauge read 96 psi. After the plumber installed the new relief valve, his pressure gauge read 65 psi. This gauge read 96 psi. I adjusted the new pressure relief valve to a different pressure, this gauge showed 96psi. I tried several pressure settings on the new PRV, this gauge showed the same 96psi. I sent back this defective sensor.
