Pride Plumbing came out and replaced two leaking 40-gallon electric lowboy water heaters (one Whirlpool and one Richmond) with two new 40-gallon electric lowboy models. First, after disconnecting their electrical connections and inlet and outlet water lines, we removed and disposed of the old water heaters. Then we installed the new water heaters, ball water shut-off valves, PEX and stainless-steel water supply lines to the water heaters’ connectors, brass drain valves, and wired up the electrical connections to the new water heaters (adding Romex connectors). Finally, we bled the air out of the water lines, ensured that the units’ temperature and pressure (T&P) relief valves were properly vented, and set the units to their appropriate operating temperatures.
