On a recent trip, we found that our bedroom floor was repeatedly getting wet. We established that the water was coming from the fresh water system and avoided the problem for the remainder of the trip by carrying our water in jugs. Now that we are home, I would like to repair the problem before our next trip. The plumbing seems to run under the floor, but is not accessible from under the motorhome. Do I need to tear up the flooring to get to the problem, or it there some way to access this area?
