Black tank Rinser

Yes, installed one on our previous MH, mounted connector right under wheel well where it was accessable. Installed one on our current Motor Home, direct into tank in water bay, bought the one without the hose because it was very accessable. Use it just about every time we dump, UNLESS there is a waiting line at the dump station. If on a FHU site, always dump, flush and redump as part of leaving procedure. Generally I finish up by leaving a bit of water in the black tank to keep it from drying. Seems to work well, and ours sprays the full width of the tank, giving a good cleaning.
