Saniflow New Installation

[booster]

I have have a job that involves installing a toilet in a hallway cupboard, looked at installing with new waste to the stack which is 6m away but 1) not enough fall 2) needs 3 bends 3) cant get a new branch t installed low enough. So will have to go down the route of a saniflow. The question is the discharge pipe is 22mm now i can run this in copper, nice machine bends and i guess where i connect onto the soil stack with a strap on boss and a rubber reducing bung 32mm to 22mm. But i want to incorporate a couple of rodding eyes in the run so was thinking of running the outlet pipe in 1 1/4" solvent and using swept bends and that way i can run the hand basin into it?? Or do i need a combined sani top for toilet and hand basin and run the 22mm discharge in copper?? I have seen the overflow pipe installations in 21.5mm solvent but using 2 45 degree bends going thru the wall will pull the pipe too far away and look ugly. Bit of a novel there i know but i want to get it right first time and keep the customer happy happy.

Thanks for any feedback Dave.

Dave, you can't tee basin into saniflo outlet, very messy, need a combined outlet. I would use solvent weld and swept bends. I saw one once ran in blue alkathene, wish I had seen how it was fixed to the stack.

I did wonder about teeing in myself and the distance from basin to stack, right combined it is good job i found a decent price for one. That blue alkathene probably had a poly tap at the other end, you see all sorts having said that i had to run guttering on a new build before xmas and the chippy bodged every bit of the facia and soffit, when i called him over ol frank says that took me ages im not changing it now. Nice !!!

Thanks for the input simon...
