What has making the "poo" go faster (or slower) have to do with all the clear water (after a complete flush) failing to remain in the bowl.
If Thetford has seen this before why haven't they fixed it? If other coach vendor are having the same problem, then it shouldn't be FR, correct??
I haven't unbolted mine from the floor for quite some time, but maybe I need to take another look at that actual exit plumbing to see if anything makes any sense at all.
I mean, it has to be a simple case of basic hydraulics or fluid dynamics, right?
Where is Archimedes when we need him?
EDIT:: DW just said she thinks she hears the "grinder" pump still running after all the water and "stuff" has left the bowl. Maybe it doesn't shut off soon enough? If not, then it would probably pump all the fresh incoming water back OUT, thereby leaving the bowl empty, right?? As I sit here thinking of it, I'd wouldn't be surprised if that WERE the problem. If so, tell Thetford/FR they owe me $5K in consulting fees.
