Water heater had a slow leak from the tank. Installed new Rheem 50 gallon natural gas water heater. Water is sitting on a short stand to elevate it above the flood level of the drip pan. The pan is equipped with a water leak alarm and the drain is capped. I replaced the expansion tank, valves, water piping, gas flex connector, and sediment trap. The water heater is lit and all of the air has been purged from the system. Thank you for choosing TE Certified!
