So went to winterize this afternoon and wouldn't ya know it, the water heater bypass valve wasn't bypassing cuz antifreeze was going into heater! UGH! Doing some research, it's one of those Thetford 9...

Since you have the lines off an easy way to check for the check valve is to stick a screw driver in the top connection of the water heater. If it hits something solid the check valve is there. If you only have one valve the check valve needs to be there and be operating to winterize.
See this video Replace RV check valve
Will the check valve be on the hot water line or cold? I removed the cold one only and didn't find one as I mentioned above. Sadly, because I am in a rush situation, I had to do the Camco temp bypass line (attaches to both hot/cold lines to water tank). Was able to get the rig filled w/ antifreeze yet not hot water tank. Did rinse it out good as it did have AF in it. Put everything back together and "mouse proofed" it so it's all set to go tmrw into storage barn. I will however, have to take things back apart in spring to re-do what I did this week. Upon doing so, I will take more time on water tank to check for valves and replace in need be.
