connecting to soil pipe

[crooner]

So that would mean digging down & adding a run of pipe which would run 9ft left to get to the new WC , that's a lot of digging , looks like a no go for me , anyway Shaun thanks for all your help much appreciated .

Hi Shaun, thought I'd give you an update, I got a quote for the work & I was shocked at the price , here's the quote.

For us to excavate the ground to allow installation of a new underground pipework, core 110mm hole through the wall and leave pipework inside to allow a plumber to connect to will take us four days to dig the ground and reinstate the monoblock

Labour per day £760.00 + vat x four days
Materials pipe work £60.00 + vat
Materials fittings £200 + vat
Concrete £40.00 + vat
Sand £30.00 + vat

£3370.00 + vat
£4044.00 Inc Vat

If the large grey is a soil pipe, you might be able to fit a Saniflo macerator toilet with a 32mm outlet pipe running along to a boss in the grey one, all above ground.
Ghastly idea I know, but it would cost a lot less than the above!

Nearly 1k per day for a ground worker I would highly suggest you get another quote

Would these work underground Equal Tee universal rubber coupling

Yes it would if you could get to clean pipe either end eg no sockets

Best to tap into the main underground drainage and install a man hole as well

Builder would be best for this (the underground pipework)

Hello again Shaun , I have fitted a underground junction & running pipe to the left for w.c.
I'm unsure which connections to use, first the one coming up from ground at that position also the one that goes through the wall , or can I justify use the 87.5 socket bends that I've been using .

 

[ShaunCorbs]

In the ground I would use a long swept 90 eg 110mm Underground Drainage 90d Double Socket Rest Bend | Speedy Plastics - https://www.speedy-plastics.co.uk/shop/underground-drainage/110mm-underground-drainage/90d-double-socket-rest-bend/

If deep you can use a Buy a 110mm Underground Drainage Long Radius Bend Cheap at EM - https://www.easymerchant.co.uk/underground-drainage/110mm/long-radius-bends/

And then above ground transition to black soil and stnd 87.5 fittings etc

How high should I centre the core drill bit inside the house,does it depend on which toilet you buy
or can you create problems if it's too high or low , I saw the diagram of a toilet it's centre was 180 mm ,
does that sound right

 

[ShaunCorbs]

185mm is a stnd for a toilet so 170 from finished floor level I normally do

Drill that hole bigger so you have some play. Then when the toilet is in position and connected up with no leaks you can fill in around the pipe with mortar.
