Removing a "Flush Valve" (no tank) toilet

Just looking for any hints about these "tankless" toilets so that I can be prepared in advance and reduce the downtime that it's disconnected.

I'm redoing my bathroom and will have to take it out at some point. I removed a thick concrete base under the old tile, so the new floor will be anywhere from 1/2" to 1" lower.

Will that first valve in the hardware, (which acts as a "volume control", I believe?) work as a shut off valve or will I have to have the water shut off by the building?

Any advice/ hints welcome.

I am assuming "the first valve" you ars talking about is the angle stop coming out of the wall(or floor) with a supply line going to the toilet. If that is what you are talking about, then just shut it off, flush the toilet. disconnect line, check for leaks (they are notorious for leaking) remove the rest of the water from toilet, and remove toilet


If you think you can, or if you think you can't, you're probably right.

I am assuming you are referring to a Sloan type flush valve. The brass shut-off screw in the end of the valve should shut the water supply off. I have never had one leak through when working on them.
If you have never made a mistake, you haven't done much.
