First check the instructions for the machine you are thinking of installing on the web site or ring the Technical help line for the machine as 32mm may not be too large,
Saniflo have changed the specification and design of the machines a standard saniflo that worked in 22mm only and not able to pump verticaly has now been upgraded to pump vertically in 22, 28 or 32mm discharge pipe work so it can be confusing and since the machine has a Non Return valve fitted in the outlet from the machine no water should be able to flow back and reactivate the machine if installed correctly.
