Have you checked in all the cupboards, fridge, oven?
Seriously though,
How did you tap into the cold water pipe?

I’m guessing Self cutting valve

it was a straight forward cut into cold water supply on other side of wall we're i installed tap... And I'm not that daft to use one of those kits.😀.. I went with the pushfit option... I'm guessing it's a pressure problem or air pocket not sure I'm was hoping for some friendly advice that might me able to point me in the right direction thanks

Is the kitchen tap on a flex it’s not kinked is it ?

I’m guessing the outside tap works or not ?
