Changing kitchen taps with an expansion vessel

[danieljamesphoto]

Hi, i'm a complete newcomer to plumbing so be gentle, basically i'd like to change the kitchen taps (just a simple monobloc mixer tap) and have looked on YouTube and think I have everything ready.

I've had a look at the system and it seems to be setup to include an expansion vessel (image attached). Would this be linked to the kitchen taps at all or is it just from the boiler which is in the same room? I'm hesitant to do anything without being certain. There is an isolator tap fitted so I think the changeover itself should hopefully be fairly straight forward aside from that but I wanted to check first.

thanks in advance,

Daniel

Looks like it could be for potable water (drinking), and you won’t need to do anything with it, isolate water and crack on.
