AO Smith water heater
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.

The Pressure Reducing Valve was replaced and the water pressure was set to 75 psi. An expansion tank is not technically required in Leawood, but this neighborhood had a water pressure of 100 psi. Meaning that without a thermal expansion tank your water pressure would rise to 100 psi when the tank heats up. The expansion tank is a buffer to absorb the additional pressure that is created from the increase in water temperature.
