You need iPhone with face recognition- pretty reliable ?

It is ! A bit unnecessary I agree - but what the hell - that time I forget my key I’ll be glad of it

Front door looks the absolute b*llocks !

Might try and get planning and build another house over it

Website says for use above ground

I can always build a concrete block housing over that short run of black pipe to protect it .

Sure guys ; push fit at the pan etc. But going into the soil pipe I think welding is best ( in this situation)

Just do solvent weld . Dry fit everything. You’ll be fine . Better to be safe than sorry !

Because it’s all in a ceiling . Welded won’t leak .... ?

Or this ? ouch at the price !! https://www.mytub.co.uk/110mm-solvent-92-5d-rest-bend-only-ss705-product-570233

Think this is it https://www.drainagecentral.co.uk/110mm-PVCu-Solvent-Weld-Soil-Pipe-Bend-925-Degrees-Double-Socket-BS473?gclid=EAIaIQobChMI-sSWsK-Q6AIVVODtCh3z1gt4EAQYCiABEgIY_vD_BwE

That looks good - not sure it exists in solvent weld - will check !

Maybe - the problem is my WC is near the in ceiling drain , so there’s not much ‘room’ to do a gentle fall .

I assume the first drawing is better i.e. try to have 'gentle' bends rather than 90 degrees....

Ok ! Won’t embed it ! Pea gravel all around and over when I’m ready .

Geberit didn’t even send a “we acknowledge your email “ response ; so I called them . Waste of time - kept saying I need a horizontal extender ( 366.887.16.1) which I don’t . He asked me to explain what I was trying to achieve . As soon as I went outside “geberit world “ he said it wasn’t possible to mix push fit with solvent . I asked him if he had a horizontal drainage pipe in his ceiling would he want geberit push fit or welded ? ? After 5 seconds of silence ( and not promoting a geberit product to me ) he said welded . I guess I was stupid expecting a geberit salesman / technical to be a ‘real world ‘ plumber . Anyway ! I needed a solution so reluctantly and with difficulty can just squeeze a 110m through ...

Main run almost done . Welded with pretty good fall Not sure how I’m going to connect ensuite wc ( hole shows point I’m expecting waste to come through ) - straight to end of main soil run I guess . Assume I’m ok to do a 90 tee right at the end and wc straight into that ...

Yep - chamfer and lube up . Agree it shouldn’t really be black pipe exterior but it’s a short run and will probably get buried in concrete

Set myself up for that one !

I use a bit of fairy ?‍♀️ ?

Yeah that was my concern - rather use the geberit supplied fitting initially . Ordered that coupler you linked to earlier - give that a try first .

Black pipe wouldn’t fit in a brown pipe coupler . That was the issue ; and I couldn’t weld a black coupler to the brown pipe . The difference in diameter is minimal but enough to cause a problem . I seem to recall some threads on here where 110mm in one make is not the same as 110mm in another make i.e one of them isn’t 110mm .

Done ?

It’s been suggested ... I would possibly suggest discarding that pan connector/bend and buying a new pan connector either straight and a bend or possibly flexible and coming away from that in solvent soil so it’s all the same . https://www.jtmplumbing.co.uk/pipe-fittings-c433/toilet-pan-connectors-c187/viva-straight-wc-pan-connector-4-110mm-p4704 https://www.jtmplumbing.co.uk/pipe-fittings-c433/toilet-pan-connectors-c187/viva-long-flexible-pan-connector-300-700mm-p6980

Now I looked online for a push fit to solvent weld converter and couldn’t find anything
