The plastic floor flange is broken and it appears to be poured into the slab. How can I remove it? Can I just ge a new flange that would fit inside the pipe and install it right over top?

Hi TLAT

What part of the flange is broken? The metal ring or the plastic pipe? They make replacement rings for this exact situation... let me know.

It is a plastic flange and the sides where the bolts connect are broken. I have read about the replacement pieces but I don't think I have enough room between the flange and the slab to fit one in.

Then you want to cut out old one as best you can... undermine slab a bit, use aviation (tin) snips and cut out metal ring. Then you can use one of the following (see pictures and then click on clam2.pdf).

These options are available at most home suppliers or at local plumbing supply house. The most important thing is to secure the new ring through to the concrete via concrete anchors... and be sure to install the johhni bolts into replacement rings BEFORE installing any of the rings.

Tell me... what kind of finished floor? You may need to extend PVC so that it is above finished floor.. if that is the case, let me know so I can suggest other ideas (or others here can! ). They make extenders... that may work here, too. POINT is that toilet flanges should sit ON TOP of the finished floor... is yours?

Get back to me.

Again, it is a PLASTIC flange, not metal and it does sit below the finished floor. The sealing surface of the flange sits approximately 3/16 to 1/4" below the finished floor tile floor.

I see... so plastic pipe as well as plastic flange. OK... how far below floor? They sell a great plastic increaser flange that gets siliconed in place (can secure this so accepts johhni bolt and secures toilet to flange).

Let me see what I can find in library to demonstrate.. will take some time.. check back in 20 minutes.

Here is an extender flange. This is sold at most home supply stores. Install 1 or 2 to set finished flange on top of finished floor. Just be sure to anchor to floor.

Any questions.. let me know.
