Mouse in the gray water tank
We had been high up in the White River National Forest in Colorado for many days. On the way out we stopped to drain the gray water tank. It ran a short time, then the outlet clogged. I used a stiff steel wire with a hook bent into the end to snag the debris and pull it out. It was hard to remove until it tore apart, and then it was so mangled it was hard to identify. Eventually we saw it was a mouse.
The top of the tank has a PVC vent pipe with a 90 degree angle and a 1 inch inside diameter. We're pretty sure that's the way the mouse got in there. Now I have it covered with some netting that was sold to tie around a washing machine's water outlet tube. I'd like to glue a PVC cap onto the vent pipe with holes drilled to allow some flow, but it might be a bit restricted. Anything would be better than a repeat experience like that.
