Tom, It could be that you might have filled the tank to full of waste and some toilet paper got stuck to the outlet side of the flush nozzel. Try putting a cup of Calgon water softener in the tank and fill it full of water. Then let it sit for a day and hook up the tank flush hose and try to clear the blockage. I had the same problem and finally had to use air pressure to blow away the sticking paper.

Yes Ted, I sent a PM to you a month ago. Wuzz up!!!

Patty had the problem and used copious amounts of water. Now she uses more water in the toilet.

Hello Tom:

The connection for the Black water clean out should have a one way check valve at the connection to prevent the escape of sewage. I have had a check valve go bad on the fresh water fill and I could not file the water tank, until I replaced the check valve.

My check valve came undone inside. Drain the tank, follow the tank flush line to the check valve, take it apart & see if the valve, sprint & keeper are all intact. I just reassembled mine and its been working over 3 years now. The valve, spring & keeper work just like their counterparts in the head of an engine to keep the, um, er, "compression" in, while allowing the clean water flush to pass by into the tank.

I had something clog the black tank flush from the outside line, not from inside the tank. Couldn't tell what it was, but insects of some type got into the flush inlet, and flushing it didn't work, because no water went through at all- nor did any air when I put air pressure on it.

I pried the old flush end off, and found no check valves or anything else-- although there is, of course, the air break. The flusher was just a small, plastic, cup-shaped (about 1/2" deep) fixture with holes in it. It's also on the drain side of the tank. Now how did it ever flush such a wide tank by pushing against the natural flow?

I removed the end and plugged the opening in the tank, and extended the flush hose to the other side of the tank. I bought a turbo-flush from CW and followed the installation instructions. Now the flush is on the passenger side so it flushes towards the drain. It also extends about three inches into the tank and spins around when water pressure is applied, so that no part of the tank remains unflushed. And it has a check-valve. Works very well now.
