Still have water heater issue.

We see that in your other post.

Are you SURE the valves are in the positions as stated?
Did you allow enough time for the HW tank to fill up? Does air come out of the hot water taps?

This has probably already been discussed but the VALVES for winterizing are elongated as shown in this pictorial.

Are your valves showing this as well...



This is a typical trailer water flow diagram that may help as well..

You have a bad check valve.

your inlet valve handle is on wrong turn to cposed and see if you get water

OK DH insists that the valves are in the right position. There is no air coming out of the hot water tap and no water coming out at all. Water coming out of the cold water taps. Hot water tank filled. Guess we must have a bad valve in the hot water out line. Correct?

Do you mean installed wrong or in wrong position? It should be opened so water goes into the tank. We have used this before no problem so don't think it is installed wrong.

You have a bad check valve.

IF they have 3 valves, which husband says they have, there would not be a check valve.

Well top valve is open. Bottom valve is open. Middle valve is closed. Now no water at all coming out of the hot water taps. Cold water taps OK.

This though gives a thought that perhaps there is a check valve.
Has OP checked{by overflow valve) to see that there is hot water in the tank?
