Obviously I've not seen all RV hot water heaters but I've never seen a check valve on an RV hot water heater.


Only the water heaters with 3 valve winterizing systems don't have a check valve.

I had this exact problem and it was the check valve. I completely removed mine as I donโ€™t need to winterize.

Remove the pex from the check valve and you will probably be able to remove the loose bits of the check valve. Reinstall the fitting and you will be good to go. Just replace the check valve before it is time to winterize if you use the pink antifreeze. I do not use antifreeze when I winterize mine so I didn't replace the check valve.

Replace it. Get the brass one to replace what is most likely a plastic one. Chris

Do you have the water line bypass valve to the water heater closed?
