Installed a Bradford White 50-gallon gas water heater in Middletown to replace an aging AO Smith unit that was leaking from the bottom. I drained the old tank, disconnected the gas line, and removed the corroded anode rod. After positioning the new unit, I connected the flex gas line and dielectric unions, set the gas pressure, and tested for leaks. Once filled, I purged air from the system and verified proper burner ignition. The customer now has reliable hot water.
