### ⭐⭐⭐⭐⭐ Brilliant concept
*by K***R on 26 June 2025*

### ⭐⭐⭐⭐⭐ Detachable Syphon.
*by M***1 on 2 May 2025*

You do not have to change the whole item,just remove yellow pin and detach Syphon without turning the water off.Just make sure it fits your system.

### ⭐⭐⭐⭐⭐ Very easy to install, especially if you are replacing a Dudley already installed
*by J***K on 9 July 2024*

Just make sure you get the correct model for your cistern. The yellow and blue colour system makes it clear what to do. You don't need special tools if you are reinstalling. Worth checking if your problem is a only torn membrane, in which case you can buy the membrane only and save yourself some money.
