Saniflo, 21.5mm or 32mm?

[Phil]

If a Saniflo has a 21.5mm outlet does it have to have a continous run of 21.5mm to the stack or can it have 32mm solvent weld all the way?

Usually 21.5 solvent weld for a toilet and the under sink unit is 32mm.

Thanks for that,

I may have to install another Saniflo soon and I was just wondering if it would still pump okay through 32mm if the outlet is 21.5mm. Can't see why not?

The reason is just I want it to be as trouble free installation as possible, I know the other makes have 32mm outlets but probably cannot be run in 21.5mm as the pump/rotor blades etc are designed for 32mm.
