Peefect fit...great replacement for the old siphon.

### ⭐⭐⭐⭐ Better model available lo
*by X***S on 3 December 2021*

This syphon works well. However, after buying it I discovered that the manufacturer (Thomas Dudley) makes a newer model that once fitted, allows it to be served or replaced without all the hassle and risk of creating new leaks that is involved in taking the cistern off the wall every time. The new model is called the Turbo 88 Will definitely buy the new model next time. Nothing wrong with the older model but too much hassle.
