HOW TO Replace toilet flange?

Why do you need to replace the flange.. Is it cracked? What kind of toilet flange... PVC or cast iron.. There may be options besides replacing the flange... such as a spanner flange... here, the flange is cracked where the johnni bolts slide into the old flange and the spanner flange slides under the old flange (where damaged) and effectively replaces the johnni bolt slot and can be secured to floor. But why replace the flange? Are you tiling a floor?

IF you must replace the flange.......

If it is cast iron then your only option is to crack the old flange out using a chisel and hammer.

If it a PVC or ABS then you may be able to use an inside pipe cutter to cut the pipe and cement a new flange into place.

Answer the questions and then we can give best advice!

Thanks very much... on the way to Lowe's to find a spanner flange! That is exactly the problem... flange cracked where the johnni bolt slides in. Any other advice?

If you find difficult to slide under the flange use a hammer and gently tap under the flange... that should do it. Just be careful when tightening down the old side of the flange so you do not crack that side, too!!

If this all helped please rate the answer below... thank you. Good luck
