Pride Plumbing came out and replaced a 10-gallon electric State PCE101OMSA water heater with a new 10-gallon electric Rheem PROE10-1-RH-POU water heater (this required us to install the new water heater, a HydraPro H10000 thermal expansion tank, ball water shut-off valves, PEX and copper water supply lines with ProPress copper fittings to the water heater connectors, and a brass drain valve; wire up the electrical connections to the unit, bleed the air out of the water lines, ensure that the unit’s temperature and pressure (T&P) relief valve is properly vented, and set the unit to its appropriate operating temperature).
