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? |
Fiberglass bonds to fiberglass extreme well.
But bonding it to plastic is a very short term fix. As soon as the plastic tank flexes, it will spit off the fiberglass patch, even if you roughen the patch area.
Depending on the size and location of the hole, you can plastic weld or perhaps use hot glue, and that might work.
The first thing to do, is examine the cracked area, and go from there.
