I am looking to add 2 new toilets one from a garage conversion from the front of the house and one from a rear extension. I want to tee both into the existing soil stack using 110mm pipe. Is this possible and advisable, both runs will be about 3m long and will tee at main stack at 90 degrees of each other. I cant see a fitting for this in Marley can anyone advise.......

Joints cannot be within 150 mm tp prevent crossflow. 
That makes sense, yet when i was browsing through the Marley catalogue it showed 110 tee for what i assumed to be for a similar purpose

Why not phone Marley and ask them.
They would be aware of regs and perhaps have designed something which will do the trick and prevent crossflow.
Let us know the outcome.

I went and had a chat with Marley. They have a corner branch that fits my needs, no problem with crossflow contamination etc. Marley were very helpful virtually told me how to do the job, so a good result , thanks for the inputs
