Pride Plumbing came out and provided a cost estimate to replace a malfunctioning 50-gallon natural gas Whirlpool 50T10-40NG 400 water heater with a new 50-gallon natural gas model with an atmospheric vent. This would include removing and disposing of the old water heater; and installing the new water heater; new ball water shut-off valves; new copper water supply lines, ProPress fittings, and a copper gas supply line to the water heater connectors; a temperature and pressure (T&P) relief valve; a brass drain valve; intake, exhaust, and atmospheric vent connections and ensuring the unit is properly vented; and lighting the pilot and adjusting its flame.
