Pride Plumbing came out and provided a cost estimate to replace a 40-gallon electric lowboy water heater with a new 40-gallon electric A.O. Smith ENLB-40 110 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 new water heater, new ball water shut-off valves, new PEX and stainless steel water supply lines to the water heater's water connections, a new brass drain valve, connecting the unit’s electrical connections, ensuring that the unit was properly vented, and setting it to its appropriate operating temperature).
