Our terrific 2012 Montana has a bit of a problem...
We're living in it full time while we build a house. Two of us, pretty normal diet. We started full time in it in March. It's been getting harder and harder to empty both gray & black tanks.
With our prior motorhomes & fifth-wheel (non-lived in) I simply pulled the black tank valve handle, and when it relieved itself pulled the gray tank handle to empty and flush out remaining "black" material. Did the black tank flusher for a couple minutes, and all was well.
Today, I pulled the black tank handle, nothing. Pulled the gray tank handle; nothing. Turned on the black tank flusher, still nothing.
This has happened the last couple dumps, and eventually it seemed to empty...
What am I doing wrong, what can be done do alleviate this, etc? We do live in the woods, but prefer to use the indoor plumbing...
