Hot water flow stopped at all sites.

[shcusmc1]

On my 2005 Adventurer the hot water flow just slowed to a trickle suddenly at all sites. I went to the by-pass valve and with it in by-pass mode I have flow at all sites. I drained the tank and while doing so used air pressure to back flow the discharge side of tank. The air entered the tank fine. any help would be appreciated.

it sounds to me like you need a new check valve on your hot water heater

It happened to me once and it was a check valve issue. A piece of plastic (which I assumed come from the fresh water tank during manufacturing) lodged itself in the check valve. I have had a couple check valve issues. The check valve up behind the HW Htr is a bear to get to. It helps to have the proper tools i.e. Beer, Channel Locks, Beer, Patience, Beer ... HTH and Good Luck.

Thanks for the input, I will check the Atwood website for the location of the check valve

Thanks to all for the information. I am in the middle of the Rockies with no access to a parts store. However, thanks to your inputs I was able to remove the output check valve from the tank and since it is for winterizing I was able to remove the inner workings and reinstall the old valve. I will replace it when I get back to home base. The hot water now works great. Thanks again to all and I will check on that panel Frank.
