Pride Plumbing came out and provided a cost estimate to replace a 40-gallon electric Whirlpool lowboy water heater with a new 40-gallon electric Rheem lowboy model (this would include removing and disposing of the old water heater after disconnecting its electrical connections and inlet and outlet water lines; installing the water heater, ball water shut-off valves, PEX and stainless steel water supply lines to the water heater's water connections, 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).
