I have a 1994 Fleetwood Pace Arrow. Yesterday I turned on my bathroom HOT water faucet and got no water. I tried the shower and kitchen and got the same results. Shut off gas to water heater and drained tank and then refilled. No water again. I then evacuated air in system and no water again.
On my motorhome model I could not locate any check valve on the water heater and could not locate any optional bypass valve. I get cold water at each location but no water thru the hot water faucets. Help!!!

The check valve could be right at the back of the tank where heated water exits. Since you drained and filled the tank again, it sounds like water goes into the tank, it's the line out that has the check valve. If if was a winterizing shut off, that would be in the supply lines and a cross connection between supply (cold) and the hot line leaving the WH.

Thanks for responding. You were the only non-commercial response! I will look again for the check valve but so far unable to locate.

It may not be obvious - essentially part of the fitting at the tank exit.

However, you will only have an outlet check valve if you have a single valve bypass system, and I'm pretty sure the 1994 Pace has a 3-valve bypass system. My '96 did. The 3-valve bypass does not need a check valve there.

The bypass will be on the back side of the heater.

Just had that problem last week and asked the same question. Here is a link to the very helpful answers.

Often the check valve is just clogged with mineral deposits. You could try filling the water heater with vinegar and letting it sit a few hours, then flush. It might dissolve the deposits to make water flow again.

Preacher boy; I had the exact same thing last week, it was a check valve, it was rapt the top of the tank at the back where the exit point is. Have lots of hot water now, like the other post said it was not real obvious. Also mine was really hard to break loose, had to use a pipe wrench, with not a lot of room. Regards Marc

Thanks for response. NO check valve on back of tank. Had repairman blow out the hot water line. OK now.

Thank you, Sir!

Here is another thread about the same problem. There are some pictures of where the check valve is located toward the end of the thread and the conclusion of what I found and the temporary solution.

Definitely the check valve.
Hope this helps.
