Shower waste connection into soil stack

[Ritzman]

Hi

Hopefully someone could help advise me.

I'm in the middle of replacing our shower with a modern low level tray and was wondering what is the best way to connect to waste pipe/soil stack.
As you can see on picture the waste from the sink comes from the left and then the shower pipe joins with current configuration when the shower had waste above floor. What is the best way to connect?
Can I use 40mm branch into a boss.

Thanks

Is that a push fit spigot elbow into the stack then connected to solvent weld?

You could cut the 32mm waste between the reducer and 45 bend and twist the 50mm tee down to 45 and solvent weld a 40mm 45 on the pipe (if there's enough to glue to). You'll need a 32mm straight coupling (either SW or Multifit) to rejoin the basin waste. It'll mean notching the joist to accommodate the new 40mm shower tray waste, be careful with this as LBC regs apply.

I reckon it is Simon.

Hi. Can anybody please advise? I have recently had a new bathroom but unfortunately the idiot who installed it has fitted the shower waste pipe so that it intrudes into the soil stack rendering the toilet unusable.
I have to get someone to rectify the job. Someone different!
Could somebody please advise me what this job entails as I have no idea! All I know is that the floor has to come up and the shower waste pipe has to be cut to stop the intrusion.
Is this a big job and approximate cost please as don’t want to get ripped off like i did with the bathroom. Thanks in advance.

Not enough detail to give you an idea of cost.

But it will be expensive.

Refer to Red Adairs quote.

If you think it's expensive to hire a professional to do the job, wait until you hire an amateur.


On a note though, if you are going to chase the original installer for re reimbursement you will need to show that they were given a chance to correct it first.

If floor is tiled etc.

It may pay to think outside the box.

How about remove the toilet (easy), stick hand down inside 4” and cut the shower pipe back- then replace the toilet.

Or if there's any of the 4" accessible above the floor eg a stub stack, cut a section out, reach in, cut the intrusion and remake.
Don't drop the tools down the pipe. Tie them all off with string on them.
The original installer should be given chance to rectify imo.
Any pics?
