No need to twist a story into a horror movie! LOL

they are easy to install as I have installed them on 2 different new TT`s. everything is exterior. On my class A its also separate of the living area. no messes and no smells from the black tank either!

I avoid dump station lines whenever possible. But sometimes on longer trips it has to happen. I often use my gray water to flush my black tank. All it takes is a twist on valve at the end of the plumbing.

Open twist-on, open black tank and drain. Close twist-on, leave black valve open, then open gray valve. Gray water will back flow into the black tank. You'll hear it, and when the whoosh stops, close the gray valve. Open the twist-on and let the black drain again. Finally close the black valve, open the gray and/or galley and finish the job.

While all that is going on, no one in line will know anything about a flush going on. And you'll be there watching and working the valves the whole time.


I'm no RV expert and this certainly will do a bit of a black tank flush, but I like the thought of the gray flushing all the poo out of the stinky slinky after the black tank drains, considering it's the drippy, gotta unhook it and store it somewhere part of the equation.
Not sure I want corn and TP sitting in the slinky until next time.

No need to get your panties twisted into a knot LOL.

Your self installed contraption may have everything on the exterior, but factory installs almost always have a cheap plastic vacuum breaker / anti siphon valve installed in a dead space in the interior, typically buried inside a vanity cabinet. They are notorious for sticking or not seating and flooding campers.

Those cheap valves are also capable of holding just enough water that if not winterized / blown out they crack, which is not found until spring when the tank flush is used.

So true! I ditched mine that were leaking with a few pcs of PVC.

It still does clean the slinky. Assuming you had a good amount of gray to dump. Gravity being gravity, not all that much flows over to the black tank. It just finds its own level. In my case I have gray and galley, so plenty of non-black to do both jobs. Once you've got the twist-on valve. Its maybe 3 minutes extra time.

Good etiquette recommendation. Don't cuss, might be kids in the vehicle behind you.

Great advice from guy was to flush a bit of fresh water into the black tank after emptying, not much and then put a couple of bags of ice in there down the poop chute before a day run. You will have just a couple of gallons and the ice will slosh around cleaning things up. After about a year, I did this and got some lights back on my black tank status checker thingy. I do this now a few times a year...

I own a diesel pickup, I always have a pair of leather gloves to fuel up with, so.....I pull up, put on my leather gloves, haul the slinky out of the back bumper, pull the black, wait, close the black, pull the two greys, wait, shut the valves, pull the slinky, into the bumper, climb into the truck and get out of the next guys way. Drag my five gallon pail back to potable water, fill it, dump it down the toilet and vacate.
Nobody around? I'll rinse till the black runs clean, hose down what needs hosing, all with leather gloves. It's not nuclear waste, and I don't get it all over me, sometimes though, it can be very entertaining being in line.

36guy, what do you do with the leather gloves when you are all done? I use disposable gloves from Harbor Freight and toss them after dumping.
