Black tank Rinser

yes, I installed mine four years ago,I really like it! Although some here think that using it while dumping is wasting every one elses time!!
I say "If Ya Got it Use it" Have yet to have an actual person get upset!
Just the keyboard comrades!!

Looks identical to the Tornado brand version I installed on our TrailCruiser years ago ... first one was busted right out of the package, second one got installed but later also broke. These things are just plastic and IMO next to useless ... tank wand down the toilet throat is simpler and does a much better job. JMO. ;)

I had two break. Third try was quickie flush with custom spray pattern.
Works better, more water flow and no moving parts.

Yes they work. Make sure to winterize the hose that feeds it every year. It's easy to forget and water left in it will freeze and bust it. I poured some RV antifreeze in mine every year.

Use full water pressure when you use it.

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.
