We have a used 2017 Minnie Winnie towable trailer and have been having a problem locating a water leak that pools in the insulation under the front section of the trailer. Found the problem last year, cut an opening in the membrane to allow the water to drain and insulation to dry and found out the heater element in the water heater corroded and leaked a little. Fixed that and checked it. This year prior to sanitizing it( it did have winter antifreeze in the lines over the winter) and there was still some minor pooling. Process of elimination, it does not appear to be sewage as there was no smell. There was also no red tint to it(antifreeze related), and as it was stored outside during the winter(southern Ontario Canada winters), leads me to believe it is rain or snow melt. There wasnít much but donít know how to locate the source without removing the floor membrane which I hope I donít have to do but also donít want to seal the membrane which will eventually rot the floor. Sealed the water inlet to the fresh water tank and donít see and rusted or water damaged entry points. Can see the pump area under the slide and it appears to be dry. Any help locating the leak would be appreciated!
