Put that little plug back in and be sure to regularly clean it. It's primary purpose is to block insects who smell the food and take the highway to it...
You mean the insects go up the drain tube and get inside the refer? If so, NEVER happens. I have 43 years as an RV tech and I have NEVER seen Insects in a refer. The drain plug on a Norcold, is to stop air from migrating back up. The Drain hose insert on a Dometic is kind of the same. BUT, the drain hose on a dometic if installed correctly(I would say less than 1% are) is supposed to have a P trap by looping the hose and then route outside the access door. This P trap will have drain water in it and insects cannot get to the refer. This is why the Dometic drain hose is so long. Doug
