: : : I broke up the floor, the plumber came in and re-plumbed the basement bathroom sewer line, and now I'm re-cementing. However, the flange (3" Sioux Chief T.K.O. pvc) is sticking above the floor line (1/4" to the bottom of the flange, 7/8" to the top of the flange).
: : : Is this right?!?
: : : Will it work for vinyl floor?
: : : If not, how about ceramic tile?

: : Brad,
: : The TKO flange will lose 1/4" in height when the knock-out is removed.

: : If you have the toilet you will be installing, you can check now.

: : I'm thinking without seeing what you have, maybe vinyl, tile no problem.

: I do have the toilet. Should I knock out the prior to setting the toilet base on? Do I need the wax ring to determine proper height, or does that not matter?
: Thanks in advance!

I would do it first with the knockout in place. You want to leave those in as long as possible. You would be surprised to know what gets thrown down there during construction.
don't bother with the wax at this time. It will compress anyway. You want to check it before the wax. Some wax with horns will prevent the toilet from setting down on the floor. Terry
