AutoPot 16mm Inline-Tap

16mm in-line taps are a very useful accessory. 

They can be added to the end of a layout when you are using hosepipe (16mm pipe). 

You can open the tap and allow the lines to be flushed, removing a sediment or lime scale build-up that might occur over time.

This will only take a couple of minutes and only needs to be done every couple of weeks.
