Replacing toilet on floor to be raised

[Hillel]

I have to replace an old toilet that cracked recently. However, the floor that it sits on has sunk about an inch where the toilet is. The floor sinking is due to the idiodic way that the crawlspace wall beneath it that supports the floor was built, not from rotting wood. I plan to jack up the floor and level it from underneath. However, the toilet must be replaced immediately and cannot wait for the floor to be raised.

Is there a way to set a flange in the drain pipe so that the toilet and flange can be raised with the floor and move up an inch in the drain pipe without pulling up on the drain pipe? Just trying to think of a way to do this without having to remove the new toilet when raising the floor.

Thanks.

You might want to look into the waxless seals that Fluidmaster makes. It's like a funnel into the drain.

It's not difficult to remove and reset a toilet. I would set it now using the waxless that Terry mentioned and then pull it before doing this work. Then I would have a normal flange installed and use wax.

I'm sure you need a toilet to be operational while you are working on the floor problem, but there is another way around your problem. Portable toilets are easily rented, and while perhaps not as luxurious as a real flush toilet, certainly will work for a short time. I wouldn't be so concerned about having to reset the new toilet as trying to do major floor repair with the toilet in place.
