This is just day 3 of a 24-day vacation and I have a leak. It appears to be related to the shower some way. The basement floor is sopping wet on the port side for the first 10 inches from the door. Water is dripping underneath along the I-beam and from unknown parts just inside (same port side). Clue is; just used the shower. The shower drain is tight. The shower faucets were just replaced and they are tight. Everything seems dry from on top. It must be coming from the drain to the holding tank some way. I pulled the release valves on all three tanks and that solved the problem for now. Maybe I should make a habit of always opening those valves first when hooked up. I haven't torn into it at all and don't want to have to until I get back. Help me out, guys. Where should I look? What should I do? Mine is a 2012 Big Country 32' fifth wheel. I may be out of wifi area in about two more days. Thanks.
