Oh, what fun. I go to flush the water system after winter. Since it was just water, I was able to see what came out. First clue: styrofoam pieces.....
in the grey tank? I closed the grey valve and started filling the tank with the fresh water flushing. Everything was ok until the tank was about half full, then a waterfall under the trailer. Yikes! I pulled the access cover to the valves, and tried again. The hole is somewhere else. So the next step is to pull the belly pan in this area and find where the mice chewed their way in.
So, once I find the hole, what is the easiest way to patch it? This is a light grey plastic tank in a mid-90's Excella. I am hoping that the hole is accessible without removing the tank. I haven't tried locating the entry fitting yet. I suspect it might be under the shower.
Do you think that a fiberglass repair kit, with 2-part epoxy and fabric would stick to the plastic?
