Changing tap valve

[durranee]

Hi all,

First time here and asking for a tip. Thank you all in advance.

I have a Bristan bath filler tap where the valve have gone bad and needs replacing and I just can't figure out how to take off the valve without damaging the tap.

I have taken off the `handle and can see the valve but the valve is a bit deeper inside of the tap and I can't access it properly using a wrench.

I'd really appreciate if someone can advise on how to approach this and/or there's some special tool that I need other than a wrench?

I have attached a photo and for reference the tap is the one in this link.

I would try a socket wrench
