Toilet flange broken at base in concrete

[David Fitzpatrick]

I have been told that I have a delima and require professional assistance before tackeling on my own. Our basement toilet began rocking when used. I pulled the toilet up and found that the builder had broken the top part of the flange flush with the concrete floor (See picture. Color is rust..hopefully). To remedy the problem, the plumber installed a metal flange directly to the floor on top of the lenolium. Well, over the years it had rusted out and the rust seeped beneath the floor.

My delima is, how do I fix this correctly so this isn’t a problem 5 years down the road or sooner? It’s a 3″ pipe so I thought inserting into the existing pipe would probably not be a good idea if we want any of my families business to go through (if you know what I mean ). I will be replacing the lenolium.

Is this a project I could tackle, or do you think this is a job for the pros?? (Cutting concrete , chipping it out, and possibly breaking the pvc scares me.)

Well, you’re on the right track. The concrete will need to be broken out around the 3″ pipe. I cant tell from the picture, but the hub of a previous flange might be on the outside of the pipe. If so, the pipe will either need to be cut then repiped or (and this isnt always possible) the hub of the old flange chipped off. It’s going to be a project for sure.

I wouldnt recommend putting in a flange that glues inside of a 3″ pipe. The effective opening is reduced too much. If it were a 4″ pipe, it wouldnt be a problem.

Good luck

It looks to me as you have a 3″ flange in a 4″ pipe, so take sawsall and cut old flange flush with floor, take a small hacksaw are a drenel drill with cuttinf wheel and chttp://www.quickfixplumbingproducts.com/toilet%20repair%20products.htmut out piece of old flange about 1″ wide , take screw driver and try to knoch it out and once you got it out start with hammer and scew driver and take out rest of flange. After it is out clean out old glue best you can and try new flange in before you glue mesure from wall to center of pipe and aline slots in flange on marks. Go to http://www.goole.com and ask how to repair toilet flange and they have different kinds to use. That web site is in middle of paragraph.
