The wifey (OK, maybe it was me) bought non-RV TP once and it clogged something. I have a sewer dump at the house, so I bought a sort of jet, but not high pressure, water wand for the house hose and ran the hose through a window and stuck it in the toilet and ran it around for a while. It cleared all that was clogging it and the black water level sensors started reading properly. I ONLY use that wash wand for that purpose.

I can't imagine wasting 30 to 40 gals. of water on each dump and doing that 3 or 4 times, what a tremendous wast of water, ...... but IF that's how you clean, then sure you have to be very careful because when you are nearing the full level you run the risk of flowing out the vent pipe and making a mess that no one wants to see, ...... I spray my flush unit for about a minute, maybe 1 1/2 mins. at the most, 2-3 gals. each time, total of maybe 10-12gals, max for my whole cleaning process, and will compare my cleaning results with the 100 gal. cleaning process any day, ...... it just isn't necessary, the flush is SPRAYING water all over the tank, washing down everything, .... but anyway, what I described is happening in post #3 is a fact, ..... do what you want to about it, but it ain't necessary to waste 100gals of water to get a clean black tank, ..... happy trailering ..............

Will appreciate any tips. Thanks
if your spraying unit has gone bad/stopped working, a simple fix is to install a "quickie flush"(link below), works great, .. and I would install it on the curb side of the tank, you'll get better results over there, see post #3, .....

fella10 - I agree, I don't need to use 100 gallons of water to clean my tank. Especially if the flush unit works just fine . . .

thanks to everybody for their advise

Dump valve open when flushing

My camper has a decal near the black tank flush stating it should only be used with the dump valve open. Besides what Flybob has mentioned, I also think the flush does a better job when the black tank is empty.
When I run the flush I can hear the pressurized water spraying against the tank sides - doing its job. If you've got the dump valve closed the spray isn't directly hitting the sides once the water level rises which reduces its effectiveness.

[QUOTE=Teaman;1396328]Teaman here.

Have been meaning to ask sort of similar question. My Black tank may not be flushing properly. I had a strong suspicion something was amiss and recently ordered a clear 45 degree adapter for the drain, to enable observation of the cleaning progress. Sure enough, the Flush sprayer gadget seems to be clogged or not installed correctly. Only a tiny trickle of water is flowing thru the clear adapter while trying to use the flush. The water hose is connected and the faucet turned full on.

Any ideas anybody. Is this flush gadget accessible or even repairable???

I have only owned this 2013 Sunseeker for about six months and am still working the 'bugs' out.

Will appreciate any tips.

Thanks[/QUOT f

First, if it only a trickle there may be a problem with flow, but we have one on the new TH and it seems slower than my old process and I still use the old process when relying on the dump station hose since the end is usually too messed up to screw on the fitting anyway.

What I do is assume at best the hose running full is at most ten GPM. I have a 40 g tank. I drain it, then pick up the end, a I've tank level and run the hose in it for three minutes.

Lay the hose back in drain. I usually get a large amount of brown and paper. Repeat. Surprisingly, the second time there is usually still a small amount or no paper, but still very brown. Repeat. Usually by third flush I am getting clear water. Done.

I have a 2010 Wildcat 5th wheel. When we bought it in 2010 the black water tank flush valve was installed backwards. The manual states that the valve only works if the BW valve is open. When we were connected to the black water tank flush & had the BW valve open there would be only a trickle coming out of the tank, which I believe was just more draining water, plus when I disconnected my hose from the black water tank flush I would get a tremendous pressure & water bolt back. My dealer said that I was not the only one that had the black water tank flush valve installed backwards, it has been working great since then. I love the clear 45 degree I installed at the end of the piping because with the cap on it I do not get a surprise when I remove the cap now!

The instructions with my flusher are to use full-pressure water. I assume because the flusher is always "on" there's little risk of over-pressure causing a water line rupture.
