Hot water pressure drop only after tap turned on-intermitent


Hot water flow and pressure drop off when any tap is turned on.Cold is fine.Happens after the system has not been used for a few hours. If you leave the tap running long enough, can hear a very loud bang noise and pressure is fine. Almost like a valve is sticking. After this happens, theflow/pressure will be good for several days. Water heater is a Superflue powervent. Would it be a flow valve in the heater.

Do you have a check valve in the hot water piping?

I have not sen one, but some of the plumbing is concealed. I think there could be a back check in the hot water heater. It might be sticking. I may have to pull some panels down to look for additional valves.
