Any way to terminate this Brita 3rd outlet/pipe?

[JohnBishop]

Hi,

  I have inherited this kitchen tap and the problem I have I don't know how to terminate this 3rd "filtered water" pipe.

If I use a tap adapter/aerator then water leaks through it from the tap.

Please advise.

Find out what size it is and buy a blank plug.  This is a random example for an 8mm plug https://www.ebay.co.uk/p/2211717247

from my measurement it looks like it is 4.3mm wide so I reckon I need like 5mm plug.

8mm OD if it's the same as mine.

This is Brita Paini. The pipe is like 8mm but the plug I need I think would be 5mm.

if it's 8mm pipe, then either an 8mm stop end for the pipe or a plug for the pushfit. If in doubt, remove the pushfit installed for a closer look at it, just in case an 8-6 reducer has been fitted.

It's definitely metric tho, as imperial JG fittings are beige.

Pipes are generally known by their outside diameter, same for the fittings.

In this case it's a straight couple connected to the pipe, so the plug required will be the OD of the pipe.

 

If you can uncouple the straight coupling (push the end in and it should release the barb) then take the fitting with you to get the right sized plug.
