Question

Help Needed With Installing Closet Flange


Hello,

I'm trying to install this closet flange:



There is a 90 degree elbow just below the concrete so my flange bottoms out when I try to push it down into the drain pipe:

Can I trim a couple inches from the bottom of the flange?
Is there anything I can do besides breaking up the concrete? There's only about 3/4" of the stub above the concrete.
In addition, the concrete is "mounded up" a bit around the stub and not level. How can I level this out so my flange sits flat on the concrete?
Here are some more photos:












Thanks all!

Won't happen using that flange into that 90

Do this;

Trim the PVC coming out of the floor flush with the floor

Remove the what appears to be a PVC ring inside the 90

Buy a flange ring repair kit and anchor it to the concrete around the pipe. Use tapcon screws

Install closet bolts, wax ring and then the toilet

Thanks for your reply.

The outer layer is a coupler. Should I still cut out the inner layer of PVC above the 90?

So I am looking for something like this?


And you're saying I won't need a flange, just the piece shown above?

Yes, that's what he's talking about.

Cut the pvc coming out?
That depends on the type of flooring you'll be putting into place - will you be laying tile? If you will be then take the thickness of your new floor into account.
If no thicker flooring then, yes, cut the pvc flush and install the new flange - your wax ring for your toilet will make the transition smooth.

The toilet flange has 2 functions. #1 - it attaches your pipe to your toilet. #2 - it attaches your toilet to the floor. So by replacing the 2 in 1 pvc unit that you do have you will be using the new flange to take care of #2 - and the screw-fittings that attach your new flange to the floor will assist with #1.

Sometimes the convenient 2/1 products such as a toilet flange with pvc stem don't solve all the problems.

I will be installing porcelain tile so I shouldn't cut the PVC flush with the concrete floor, more like flush with the height of the tile, right?

So I'll install the toilet flange repair ring directly on the concrete using tapcons:


Then the wax ring sits directly on this stainless steel ring and I'm good to go?
Any ideas for leveling the slab where the concrete guys mounded it up around the stub?
Thanks so much!

If you're using the replacement ring it might be best to cut the pvc flush, install the flange to the floor and then use spacer flange pieces (small plastic ring(s) that you silicone together to make up the gap between the surface of the new flange and the bottom of the toilet.)

Install the tile and cut the pipe flush with the top of the tile. Then install the ring on top of the tile
