Hi I’m currently doing an extension I’ve got a few questions but I’ll keep them seperate , question 1 , I need to move my soil stack outside about 6 ft to the right , am I ok to tee into a second soil pipe via a new Y branch fitting then disuse the original pipe ? The pipe I’m planning on teeing into runs to my downstairs toilet ? Is it an issue having two toilets to the same pipe etc etc
I did consider doing that but how would you go about linking it up within the manhole ? It’s a brick manhole with cement inside ?
No not issue running two toilets into same pipe. Will the soil pipe be vented? I do think it would be a better job if the whole section of pipe is replaced, and not just a connector from clay to plastic, unless you use clay. Not going to be easier but a better job overall, and assured that its all new pipe into the manhole.
I was hoping to cut the pipe put on Y fitting then put pipe back on which then runs into manhole , only trouble is it’s all cemented in so may have to chip away some to get pipe to move then cement back around again
oh in that case just cut and connect onto the existing pipe. Not going to be any easy job to break up the concrete as will be strong.
Yeah that’s what I was thinking cut pipe and put in the new fitting , only trouble I can think of is that I will need one part of the original pipe to be able to move to be able to slide into new fitting so may have to break concrete under manhole so that 3ft lenth will then slide ? That’s my thinking ?
Should be ok. Once you dig the trench there will be a play with the pipework, so can be lifted up so you can get the fitting on and the pipe against the wall with clips. Install access branch as well for rodding purposes. Use a rest bend on the main stack. With the ground floor toilet, position the T branch with the inlet raised , so there is a step, this will avoid the inner section from getting blocked.
Is having a ridding point essential would you say as I had thought of putting the screw on access fitting at the bottom off stack for rodding similar to what’s already there
Yeah that’s what I was planning on doing , excellent sounds like a plan , main query was if two toilets into one pipe was ok so all sounds good to me , I’ll mention it to building control tommorw as there out to check foundations anyway
Hi, you're supposed to fit an access chamber where there's a junction, pretty sure building regs state this so building control would probably pick up on that. Not a big job to do, you'd just need a small access chamber instead of the junction or you could branch the 2nd toilet into the new soil stack and just have the one connection underground
Didn't think of that. If the ground floor WC can exit out the wall than its better to connect into the main stack above ground level.
We ain’t half making this complicated, move the soil stack, excavate from stack to manhole picking up the original pipe run, you can have a bend right at the manhole and that’s how you connect the moved run
Just breakout the benching and a bit of the mh wall, cut back the existing pipe back to mh wall if need be to make more room , put new run in and then re build mh wall and rebench. to suit. Simpler than trying to excavate around original pipe and make new connection, probably faster as well.
Thanks for all reply’s and ideas , I’ll see what building control say today , I’ll suggest just teeing in and then you can rod via original manhole and via the screw on access at the bottom of stack
