Hello all, The Flushking cleanout valve wont fit on my 71 safari black tank discharge. I believe its a thetford valve. Is there an adapter available. Thanks Robert

Hi all and thanks again for the replys, Well I have read about the backup in the shower and vent pipe. But I cant find a soulution. I tried my flush king this past weekend and it backed up in the wet bath shower pan. If I plug the shower drain,Lav drain, and tighten strainers in the galley sinks am I good to go or will I blow things out the vents. Gosh I,m wandering if the hose wand is better. Thanks Robert

Berto, I have had the same concern about blowing black water up the grey line. So we went with the $6.89 stick "wand thinghy" from wall mart. It works well in my opinion. I never knew that the bottom of our "black tank" is acutuallly WHITE!

Yeah but, Mike, you have to run a hose through your trailer to use one of those. Is blowing water up one of the gray lines using a Flush King really a danger? You just have to have to be careful not to overfill the tank when you flush it out.

With the way ours is set up my concern is if the black water goes into the bathtub and my two year old daughter is the next one that takes a bath... I dont really want to find out how sick we could get her...

I have an access in the rear storage compartment that comes out beside the stool. With a six foot hose on the wand I can attach it at the rear bumper.

yes, it is...and you can't "not" overfill the tank. it sits on the floor; the shower pan is floor level...anything in the tank, at all, will flow into the shower pan, if the dump valve is open, and the sewer outlet is plugged. (in this case, by water being forced upward).
you basically can't use a flush king or sewer solution in these older trailers with no grey tanks, and floor mounted black tanks. Unless, you open up the belly pan, cut the grey lines, and put in valves that can be closed so that water can't go backwards up the lines.

I've used the flush king on both my trailers and never have had a problem. The 73 Safari has the black tank above the floor and the 69 tradewind has the tank below the floor. So I deal with both the below and the above the floor tanks. I have no problems flushing the tanks.

Well, I guess I shouldn't speak out of turn, irt the "flush king", because I haven't actually used it. . I was picturing it forcing water UP, without allowing it out, but it doesn't actually do that; there is still a 3" pipe that lets the water out as fast as gravity will take it, and I'm sure thats what prevents anything from flowing up the wrong pipe.

But I HAVE used the "sewer solution", and that's another story. Its small output hose creates a slight restriction...particularly if anything solid gets caught in there...and it does, if for only a fraction of a second. I saw a chunk of TP get stuck in the line, and it was there for a half a second before the water jet could disintegrate it, but that was all it took for the 3" column of poopy water to seek another exit, which it found, in my shower pan.
