Pride Plumbing came out and replaced a leaking 50-gallon electric Rheem commercial water heater with a new 50-gallon electric Bradford White LE150L3-3NLWW commercial model. First, after disconnecting its electrical connections and inlet and outlet water lines, we removed and disposed of the old water heater. Then we installed the new water heater, a thermal expansion tank, new ball water shut-off valves, new copper ProPress water supply lines to the water heater connectors, a new brass drain valve, and wired up the electrical connections to the new water heater. Finally, we ensured that the unit’s T&P valve was properly vented and set the unit to its appropriate operating temperature. We also insulated the unit's copper water inlet and outlet lines.
