On Dometic refers, the end of the drain hose has a cap with small holes, that does 2 things, to prevent insects going up and to restrict a small amount of air from going back up into the refer. When installing the refer, they supply a LOT of extra white drain hose for the installer to either loop and make a P-Trap to stop air intrusion. I HAVE NEVER SEEN AN OEM INSTALL IT THIS WAY.
On Norcold Refers, they have a drain cup next to the burner flue with the drain hose installed in that cup. On the end is a plastic check valve that opens when water fills the drain tube. DO NOT allow the end to lay in the drain cup. lift it up a 1/2 inch and have it dangle just above the drain cup. That will allow the check valve to do its job and not get clogged up. Clogged up Norcold drain check valves are very common. Doug
