Headhunter Royal Flush

Yahoo Message Number: 77370
Now that we're back in the coach, we have a new emergency issue in our 2003 Lexa. When it rains it pours :-)
The Headhunter Royal Flush hydrovac toilet won't flush. To be specific, it won't empty at all, it fills but zero water leaves bowl. I suspect a large amount if tissue may have been used on the last working (or partially working) flush.
Worked fine before. I dumped tanks in case black was full, but no change at all.
I suspect something might be blocked ny a wad of tissue, but I'm not familiar enough with the operation yo know what. Manually emptied bowl as much as possible and rooted around with a coat hanger but no joy.
If I do need to pull it, is there anything that needs to be disconnected or does it unbolt and pull straight up off a wax ring like a regular house toilet?

Thanks,
Jim

There's a back flow valve somewhere between the toilet and the final 90 angle bend in the pipe down to the black water tank. If you will shut off the small valve on the upper left side of the tank lets water flow to the rim of the bowl, them empty the bowl completely manually. Then take a piece of rubber , shower drain cover, place it over the drain of the toilet bowl, and hold it in place firmly so water and air can't escape; then have an assistant push the button for 4 or 5 seconds the pressure will blow the restriction out of the clogged back flow valve. The back flow valve on my coach is underneath the false floor of the nearby sink cabinet above the floor, if you want to verify where the clogg is first.

The "turbo" valve on my Lexa is inside the back of the toilet. You need fairly slender and long arms to reach it. You have to pull off the cover behind the toilet, which is held in place with a couple of velcro strips. The timer control for the flush duration is back here also. Reach way down on the side opposite the flush switch and feel around the supply lines under the bowl. An inspection mirror and a flashlight will help you locate it. It is a 1/4 turn petcock. This valve supplies more pressure to the flush jet. Switch the valve back after the clog clears, or the bowl will not fill.
Before I found the valve, I used an expanding bladder on the end of a hose like the one here. You can get these at home improvement stores. Search lowes.com for "drain cleaning bladder". I use the small size. It is very difficult to get a good seal with other types of plungers. Just be careful not to apply too much hose pressure.

The drain elbows are far to tight to get a snake through them.
