Nasty smell from under kitchen sink
New to this forum and new owner of a 2003 26RBS Wildcat (body type TT). We absolutely LOVE our Wildcat and have taken it out 5 times since April with the next trip scheduled in a few weeks. But we're having a problem with a really bad smell that seems to be coming from the galley tank (maybe, not sure). The smell comes from under the kitchen sink, permeates the camper when it's closed up and not in use, then dissipates when the windows and door are open. While camping just this weekend and sitting outside under the kitchen window, I noticed that when the kitchen faucet was turned on, the smell seemed to seep outside, from under the trailer, in that location. We've run freshening tablets thorugh the kitchen plumbing and it made absolutely no difference. Since we bought the trailer used, we're also not exactly sure where the galley tank is and how it operates on this model. Is there a valve to shut it off from the main gray tank or is the "equilizer" method the only option? We just dumped all tanks and the galley tank says empty but the gray tank says 1/3. (the black guage is never accurate; we know it's empty but it's reading full.) Any ideas, anyone?
Thanks for any help you can share!
