Connecting 32mm waste to 22mm copper

[Tractorboy]

Any ideas on how to connect a 32mm plastic anti-syphon valve to a 22mm copper waste pipe? (its on a Saniflo poo-pump. No flames please!).

There is a rubber reducer available for this. 32mm to 22mm (1=BC to =BE). I used it with 32mm pushfit bartol waste pipe but l think it will work with solvent weld ABS as well.

Them saniflo's are a handy machine but careful of excessive paper, ST's and condoms. Really on suitable for a private house.

Very, very carefully!
