Toilet drain with offset configuration

Hello!

I noticed a ring of gunk around the base of the toilet. Pulled it to see if the seal was bad (which it was). Now I'm looking down the drain, and it doesn't seem like the best flow path. it's a Kohler toilet on a plastic flange but then it has an offset there. It's a 3" diameter hole at the top. I haven't been under the house yet to see how the plumbing is connected down there.

I'd just think it would be a flange and then an elbow, but this seems to be more than that.

Any thoughts? Is this OK? (I'll head under the house and post those pictures also.)

I just figured now would be the best time to replace the flange and elbow (if needed) while I have the whole thing apart.

Thanks!

They put the pipe in the wrong place and it wouldn't clear the wall so they used an offset elbow. That is what they are made for.

Ray,
Any of the wax-free options you recommend for this offset?
-Fernco Inc. FTS-3 3-Inch Wax Free Toilet Seal
-Danco 10718X Perfect Seal Toilet Wax Ring
-Sani Seal Llc BL01 Waxless Toilet Gasket
-Fluidmaster 7530 Better Than Wax: Wax-Free Toilet Seal
-Korky 6000BP Toilet Wax Free 3" Rubber Seal Kit

(I think that most of these try to line up with the center of the circle, and with my opening offset, the seal would block some of the flow(?)Name:  flange.jpg

In case anyone is interested, this is what it looks like under that flange. So it has that offset, plus all these other pieces. And that's quite the hole that was cut in the joist.

I'm thinking I should cut this off, replace the flange and down pipe, and sister a section of joist to shore up that hole.

If anyone has any thoughts of this, I'm all ears.

How much money do you want to spend?

Pull back a bit (or use a wide-angle lens setting) so I can see the wall behind the toilet and also what is beyond that floor joist that was so badly butchered. You might be able to move the piping and then use a toilet with either a 10-inch or a a 14-inch backset instead of a "standard" 12-inch backset.

Furd,

No pictures yet, but I measured the backset and it is exactly 12". So it's where it is supposed to be. Looks like they put the offset there to clear the joist and reach the drain piping. But it's all PVC/DWV, so it's not like we are working with cast iron.

So, I'm thinking an Oatey 434954 (SS ring 4"), replace the nails that are holding down the plastic offset with stainless screws, use a 22.5 angle to clear the joist, then a small section of pipe and an elbow.

Then sister the joist.
This opens up my options for wax-free rings (most won't work (without modification) with this type of offset flange per my e-mails with the manufacturers)

Should be fun.
