Pride Plumbing came out and replaced a leaking 40-gallon natural gas Whirlpool N40S61-403 water heater (located inside an AquaHut) with a new 40-gallon natural gas A.O. Smith model with an atmospheric vent. This included removing and disposing of the old water heater along with its electrical wiring, venting, and gas and water supply lines; and installing the new water heater, new ball water shut-off valves, new PEX and stainless steel water supply lines and copper gas supply lines to the water heater connectors, a temperature and pressure (T&P) relief valve, a brass drain valve, atmospheric vent and ensuring the unit was properly vented, and lighting the pilot and adjusting its flame.
