Soil Pipe Question

[Fletch1]

How far up should the soil pipe go into the toilet flange? This would seem to have another inch to go. Thanks.

I posted this in the toilet discussion forum earlier but perhaps this area is more suited to the question.

We cannot tell from the photo how deep the flange is. If there is 3/4" of solvent-welded connection, I wouldn't be concerned about it.

Spec says A: connection 3" Sch. 40 spigot. So it seems to be something like a 2" connection. My main concern is I want to use the Fernco 3" gasket . Looks like only 2 of the 4 barbs on the Fernco will get into the soilpipe.

A 3" hub is 1.5" deep.

You are trying to use one of these with that closet flange in your photo???

Oh, wait. You probably mean this:

Never try to use one of those with a toilet that has had wax on it previously. Given your flange, even if your toilet is new, I think you should make a different choice.

I think you will need to tell us more about what you are trying to accomplish, as it is not clear from what you have stated in your posts. I don't recommend anything that further reduces the I.D. of the riser.

I think the question he might want to ask is "how do I best attach a toilet to this closet flange", or "how do I best attach a toilet to this closet flange with a waxless solution?" I presume there are slots for the closet bolts, although they are not clear from the photo.

The flange is a 3" Sioux Chief total knock out with a 2.427" hub depth . The Fernco FTS 3 has an ID that is the same as the toilet outlet so I'm not sure if the reduction to the riser would affect things since the toilet already has a reduced outlet? I've looked several of the waxless seal options, this one seems best for me.

Unless I am planning to remove and reinstall the toilet multiple times, I find a standard wax ring to work more than adequately.

I used the Ferco FTS 3 without issues of any sort. I think I made the right decision. Time will tell.
