What to with this toilet waste pipe for laying subfloor?

[Joe Fixit]

The one I recommended is designed to allow the finned end of a Pan Connector to fit in snugly, and make a suitable seal. Ideally I would suggest you leave it so it's slightly proud of the new floor, and cut the flooring around it snugly to help keep it in place, then fit your Pan Connector into the extension section above finished floor level.

Use rigid Pan Connectors wherever possible!

Have you got any experience with the same style connector but with an offset? Just saw this and thought I could do with he pipe being offset a few mms away from the wall

No, but I don't see an issue with it in the vertical plane, gravity will do its thing!

 

[Joe Fixit]

Just noticed the offset is only 10mm which isn't much. I tried looking for 45 degree soil Pepe extension/connectors so I can get the soil pipe popping up the floor some 50mm from there it is at the moment. But I'm struggling to find many places stocking this or it's very expensive.

I spotted this but it's for underground so assume this is not suitable?

Ignore above, just spotted this one. Is this ok to use and put on the existing grey soil pipe. And then get the straight rigid extension to connect on top of the offset? Due to the vertical offset, would I need to support the additional pipework as it will be kinked going up?

I bought the straight rigid extension but encountered a problem. The bottom of the back of the toilet has a lip which narrows the opening. It's a back to wall toilet so with where the soil pipe is now, I can't go straight up. In the photo, I've even put the toilet right up against the wall (boxed in corner).

I was wondering if I should get a couple of 45degree pipe connectors. But I seem to struggle to find these and/or they're ridiculously expensive.

Or should I just go down the Flexi pipe route? Now I know why they had Flexi previously

 

[Hugh Jaleak]

Flexi looks to be your only choice without major surgery on the soil pipe.

Thanks. I'm thinking that way as well.

Is there a way I can almost creat a bracket at tile floor level to help keep it in place a bit better? Only asking as the the overall Flexi section would have to be massive as the pan spigot is set back a bit as well as the distance below current floor level

 

[CountryFan]

Maybe something like this could help?

Thanks. Greta idea but I effectively need two 45degree bends to make a 'chicane' going up. If I was to turn this 90degree end piece facing up, I think it may be a weird angle and would need another bend/angled piece. Don't think this would work as I've not got a lot of space to play with

 

[Joe Fixit]

Looks like including the extra space needed for when the toilet is pulled out, I need over 430mm. So looks like the Flexi would need to be 'up to 600mm' range. McAlpine doesn't do one this long so any recommendations for other brands please?

Flomasta? Flopast? Fluidmasta? Viva?

Wondering if you'd get away with a McAlpine DC-1 into the old collar, come off that with the 2x 45° bends or an adjustable bend, and then a pan connector?

I did originally think to try using two 45degree so it pops up close to the centre of the toilet. But can't seem to find many McAlpine 45degree bends pipes?

Any idea which adjustable bend you'd recommend. Google shows lots to choose from

 

[Joe Fixit]

Is something like this ok? Would I still need the dc1 connector?

Can't seem to find McAlpine stuff as they tend only to do pan connectors

Might be ok, but this is what @Hugh Jaleak was referring to

thanks. yes meant i would get a DC1 connector and then two 45 (or 135degree bends).

tried to sketch this one out - hopefully makes sense.

also, i wondered if I could use underground soil pipe for the bends as its almost half the price of the soil pipe?
