Remove existing water heater and haul away. Furnish and install new 50 gallon gas water heater with new tank shut off and thermal expansion tank with bracket. Also install drip pan under heater. In crawl space install sump pump with basin. Run vent and discharge. Installed new water heater, and new basin and sump pump in crawlspace. Also installed new PRV. Tested all work and no leaks were present at this time and everything was working as it should. PRV was replaced and water pressure is low. Stated to customer that main waterline may be galvanized, which is restricting water. Will send estimate for new water line.
