Hello,

I am ready to pour concrete and patch the cut I made in my garage slab to add a new toilet. I have a few questions first and would appreciate some help.

I am using 3 inch ABS with the type of flange that glues into the pipe.

1) The top of the flange goes flush with the concrete? Eventually I will be adding tile but the toilet will go on without it for now (no money for tile!)

2) Do I pour the concrete right up to the pipe or do I wrap the pipe with cardboard or something?

3) Do I need to bolt the flange down to the concrete? If so, should I add bolts and then wetset them in the concrete?

Any other tips? It needs to be done right the first time I'm guessing!

Thanks!

You have options. You may set tiles around the flange to raise it up to
The correct elevation and set the bowl up on a few tiles to have the right elevation all around **or** You can set the flange and toilet on the cement floor and when you tile use a double wax seal with a funnel when you set the toilet.

2) Do I pour the concrete right up to the pipe or do I wrap the pipe with cardboard or something?
If you plan on using a outside flange purchase a styrofoam closet wrapper and wrap the stub up before you pour the floor.
3) Do I need to bolt the flange down to the concrete? If so, should I add bolts and then wetset them in the concrete?
You shouldn't have to tie the flange down the soil and cement pour should keep it secure, but if you need to tie it down you may use cement screws, (Tapcons) to do it.
4) Any other tips? It needs to be done right the first time I'm guessing!
Keep the middle of the slots centered. There won't be any room toadjust after the glue sets up.
If any more questions come up feel free to ask. Regards, Tom

Thanks Tom! I'm using a flange that glues and fits inside the 3" pipe. So I can pour right up to it?

Also, there is what looks like to possible ways to line up the flange to accept toilet bolts later. One has larger holes (longer grove) than the other. Do you know what is best to use?

The longer slots give you more room to adjust. Good luck Tom
