Question about Water Heaters
I have a tankless gas fired water heater in the bathroom. It is 9 years old. After the tank was cleaned with an acid wash, the hot water stopped delivering to the sink faucet. The tub and shower have sufficent pressure to ignite the burner (the burner works fine) but there is still no hot water delivered to the tub faucet. I have disconneted at various joints to confirm that water pressure flow is adequate and at the heater it appears so. In fact when you first turn the water on the water delivered from the tank is warm to hot for all of 1 sec. then to tepid to cold, again only at the tub. If I turn the tabs on at the tub and the sink there is no increase in flow. Any ideas on how to repair or what might be worng?
THE WATER IS RECIRCULATING IN THE UNIT. MAYBE CAUSED BY THE ACID. TRY INSTALLING A BACK FLOW PREVENTER
