Pride Plumbing came out and replaced a leaking 38-gallon electric A.O. Smith ECLN-40 200 lowboy water heater with a new 38-gallon Rheem PROE38-S2-RH95 B electric lowboy 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 water heater pads, the new water heater, a thermal expansion tank, ball water shut-off valves, PEX and stainless-steel water supply lines to the water heater connectors, a brass drain valve, and wired up the electrical connections to the new water heater. Finally, we bled the air out of the water lines, ensured that the unit’s temperature and pressure (T&P) relief valve was properly vented, and set the unit to its appropriate operating temperature.
