- MFLNomad IIIt may be that the sprayers on the end of flusher are plugged. You should be able to hear it spraying, if not a lot of other noise. Yes, if water was going in, it would be coming out. :)
Jerry - agwillExplorerBackflow prevention vale stuck closed. Needs replacing.
- ^^^^ what they said ^^^^
- old_guyExplorerif you have a back flow device installed inside the TT and it looks like an "L" they are $75 each, get rid of it and put a 1/2 inch pipe in to connect the tube and use a backflow device on the out side of the TT, a lot cheaper than $75
- frankwpExplorerI had the same problem. Tried bypassing the backflow preventer, still didn't work. The problem was a plugged nozzle in the black tank. It had a cylindrical screen that had gotten clogged with fibrous gunk. I cut the screen off & soldered on a small piece of 1/4" tubing with the end crimped slightly to form a nozzle.
Now it works far better than it ever did, even when brand new. It was actually a pretty easy repair.
