Came out today to replace the old and leaking 30 gal nat gas water heater with new AO SMITH thin diameter water heater due to the location of the unit in the laundry room. Added new ball valve shutoff, new properly supported thermal expansion tank, new gas shutoff, and new coated gas flex per code. Capped the pan line, as there is nowhere to run a drain line to. Reconnected the t&p relief line that goes through the floor with cpvc pipe and fittings. Once we got water turned back on, filled up new unit, got all air out then lit the water heater. Everything all good and no leaks. 6 yr manufacture warranty 2 yr parts and labor through us.
