Pride Plumbing came out and replaced a leaking 10-gallon electric A.O. Smith lowboy water heater with a new 10-gallon electric Rheem PROE10-1-RH-POU lowboy model. This included removing and disposing of the old water heater; and installing the new water heater, a HydroPro HPTET2 thermal expansion tank, ball water shut-off valves, PEX and stainless steel water supply lines to the water heater's water connections, a brass drain valve, connecting the unit's electrical connections, bleeding the air out of the water lines, ensuring that the unit’s temperature and pressure (T&P) relief valve was properly vented, and setting the unit to its appropriate operating temperature.
