Advice for trimming down pipe to fit flange and having toilet flush with floor

[jrouttusa]

What is the best way to trim the top off the pipe coming up through the floor?

I've rebuilt the utility room floor and it is about 1/2" lower than before. Toilet ring sits up too high toilet sits about 3/8" above the floor. I'd like to trim the pipe to below floor level without having to remove the entire floor.

thanks in advance for advice.

I am not sure what you have there.

EDITED because I misread the original post.

One other thing I am wondering is if you have the remnants of a waxless or other seal atop the actual closet flange. If that is the case, you should be able to pick that off with fingers, putty knife, etc.

But 3/8 higher than the floor should not be a problem if you use wax. What I don't see is what is going to hold the closet bolts down. A repair ring is one way to give that. If you use wax, read up on using shims.

Another thing to consider is the Danco Hydro Seat. It is like repair ring with a tail. Use wax ring under.

Thanks for your reply- cat usually gets fed in that room and family is upset with only 2 of 3 toilets available

The top piece is like a flange, but is stuck to the pipe. Closet bolts should not be a problem as there is a box screwed into the joist and cross member that is sized for either a metal ring or other flange.

I'm thinking of just cutting the top 1/2 to 3/4 " off, allowing a flange with extension to fit down in the pipe. The only issue is that it will be a tight fit to get a saw on it - Any thoughts?

They make an inexpensive inside pipe cutter...essentially a small circular saw on a shaft you put into a drill.

Can't see exactly what you have, but a fitting saver is a bit designed to ream a pipe out of a fitting, that might do what you want, too.

The socket savers cost more...just get the right size, but here's an example . Jones Stephens Pipe Socket Saver 1 - Ace Hardware

I misread your original post. I had thought you were saying that the closet flange sat 3/8 inch above the floor. I missed that it is the toilet that sits 3/8 inch above the floor.

I don't see slots. Are you sure there is not a left-over from the previous installation that you could not pick off?

It looks like you have a bend not far down. If that is the case, your plan may have a problem.

How far down is the vertical section down the hole?

How about a photo from the side more, with a ruler sitting atop the old flange.
