Rated 5 out of 5 by from Simplicity itself! Great piece of kit, does what it sez on the tin! Adjustable height makes a perfect fit, and so easy.

Rated 5 out of 5 by from Makes Next Time So Much Easier Given the siphon diaphragm has a limited life and, with the cheaper fixed siphon flushes, its a major water-off strip down of the cistern to replace I would recommend spending the extra money now to make the job of replacing that annoying little piece of plastic next time. Just remove a simple but reliable plastic locking system and lift the top off to access the diaphragm. Also has all the features to set different flush volumes and modes.

Will this replace a lever operated siphon with a 2" outlet?

Asked by: Hagbard

Can I disable the duoflush feature ? How ?

Asked by: Jaizan

Size of out let

Hi I need a handle flushed 2 inch outlet do you sell anything like this?
Asked by: RichardC83

What height to adjust it to?

This siphon can be adjusted between 7½ and 9½, but doesn't give any details on which to choose or why. Currently I have it high enough that it fits inside the cistern without too much spare, just because the old one looked like that.
Asked by: RichardTea

Will this work with a right hand side flush?

Asked by: Ecky66
It worked OK for me with a right hand flush.
