A new water heater was installed and a thermal expansion tank was installed. The water pressure from WaterOne was 130 psi and the PRV reduced it down to 75. This brings the water pressure in the house up to 130 when the tank is heating water. In this environment a thermal expansion tank is recommended. Also installed new shutoff valves and replaced the saddle valve.
