Toilet Flange Installation Video

VIDEO SUMMARY

The toilet flange must be installed on top of the cement board just before the ceramic tile goes in place. It is critical how it is mounted. Mark a line across the flange where the toilet bolts come up. Install this flange so the mark is exactly parallel with the wall. This will ensure that the toilet is square with the wall.

How do you remove a broken toilet flange? The toilet flange is broken and causes the toilet to rock.

Hi,

Do you install the toilet flange 12" on center from the stud or expected finished wall.

Q2) in the video you mention glueing the flange above the cement backer board correct? What sort of glue would you recommend befor bolting or lagging to the floor?

Thanks

You would measure 12" from the wall, not the stud, as the toilet bowl will be against the wall, not the stud. The bolt holes in the base of the toilet would not line up if you measured from the stud.

Also when he talks about gluing it I believe he ment gluing it to the PVC piping. Which of course would be PVC glue (cement). Once it is glued in place to the pipe, it must be set pretty quickly because once it sets, it will not budge.

An existing toilet on a concrete floor. The flange is cocked now. How to remove flange and replace with a new flande? I don't see any bolts holding it down. Is it glued to the piping below? We need to replace the old flange because water leaks out very slightly even with a new wax ring.

I am putting in ceramic tile. I hear the best thing to do is to place a new flange on top of the tile however how do I get the old flange out?

On the second floor, I had to tear the entire bathroom floor out, exposing the joists. I leveled the floor with long shims (and sister-boards).

The exisitng ABS toilet flange is significantly below the new floor elevation. I can cut it out and replace it, but what should I do? (the flange is broken too)

I need to lay a new plywood floor down, and then the cement-board on top. Do I leave a new random stub of ABS pipe sticking out, then lay the plywood and cement board down, then cut the random ABS stub flush with the cement board?

Do I pre-cut the ABC stub so that the flange will fit into (or onto)the pipe, after the floor has been installed?

When does the flange get installed? There will be ceramic tile, which nobody knows how thick it will be when finished.

I am in the exact same shoes as Patrick B. I had to rip the old underlayment out because of water damage. I cut the ABS pipe to remove the old flange and installed a new one. I am yet to connect the 4" stub and the new flange to the abs piping. Since my abs piping is "floating" in the air I placed a piece of wood underneath the pipe (making sure not to stress the pipe at all) and plan to install the plywood underlayment and the cement board and install the flange through the cut out. Is this the right way? I dont want to cut the underlayment and slid it under the flange for many reasons (long story). Is this the right way?

I have the same problem.Due to the tile being too high and unlevel, the toilet has not sealed well with the flange and wax ring. I now have a cracked flange and the wood under the tile is rotted and needs to be replaced. I want to remove only enough tile to replace the plywood, flange and then put down new tile. Just not sure the best way to make it happen
