Soil Pipe Branch issue - Ensuite, to Saniflo or Branch off?

I enclose a photo of our current waste system which has 110mm Grey Marley Soil Waste and simply runs one toilet into it, as we now have an extension and on the other side of the soil pipe we wish to add a toilet and sink.






what I intended to do is to get this out and put a T-branch of the same dimensions so I can run another soil pipe from next door into the extension I have just had built, this would be at the same level etc.

But after lots of investigation and hardly any space to work, and the fact the pipe is solvent welded below and has another 3 fittings which would mean taking out a fitted bathroom too and kitchen, I don't think this is an option now, the thing is if I started it and it messed up then I have no waste upstairs at all which would not be good. We can't put soil pipe outside as conservatory below etc.

Therefore I am thinking along two lines, possibly a saniflo and go for a more expensive one or a better one but even with this how can you run the 22mm pipe into a branch? I mean can you drill a 22mm hole into one and then cement it in? or can you only do this into the soil pipe itself?

My only other option would be if there was somekind of flexible soil pipe available? so I could hack off the soil pipe further down and have the flexibility required.

Alternativly, is there a specialist type of plumber that could do this or am I asking a lot? as the couple of plumbers I asked didn't want to know as too much trouble (can't blame em).

Thanks

saniflo- warning read this

thanks for warning, but surely this is the easier way rather than what I have to do otherwise, besides if mainly used for number 1's then can't go that wrong surely.

I am not a plumber or heating engineer, i go by what i read on the forum,
I would also say that unless its a urinal some onw will use it for something else. my other half throws cotton wool face pads down our loo, now hink what else is cotton wool and have one of them go into a macerator.

it gets blocked and you have to open the macerator

the outflow pipe of the macerator will still be full, where do you suppose that is going to go?

OOOOOOOOhhhh taken many of those out of saniflo's as well as lots of other intertesting items. Gota say u need to bite the bullit & add a double junction in . its criminal to fit such a 2nd rate job thats gona be noisy & trouble some. they really are a last resort. if u attack the junction with a big hacksaw & old woodsaw u'll have 3 pipes to deal with as seperate issues. the tops a doddle. cut it back 12" higher & forget it 4 while. take up some boards & cut the bottom off at the bottom of the glued socket. split the pushfit socket on the old branch by sliting it on opposite sides with the old wood saw, glue a new single socket on the bottom hole & fit the new double junction into it after sliping it onto the old branch pipe. then with 2 slip double socket couplings fitted flush onto a new 12" pipe connect up the top. will need tapping into plce with a mallet. lots of lubricant as well.

thanks, but can't take up floorboards as under bath in new bathroom which I just don't want to take apart for this.

the trouble is you got a bath going in lower and a sink higher up the pipe and obviously the original toilet too, the whole thing is a nightmare...

Is there a specialist sort of plumber who deal with waste/soil pipes etc? I mean would they cost more than the £300 I would have to outlay for a saniflo?

It doesn't look too difficult. The space is an issue, but i cant see an experienced plumber taking more than a day to do this

I wish u were nearer i'd come an do it. Any timeserved plumber with good experience should sort that 3 hrs tops £150 should kill it .u should ask around 4 a good reference.
