Which tool can open this valve for me?

[Anna Liu]

Hi all,

I'm having problem with my shower mixer. I wanted to change the internal mixer by taking it part. However, I don't have the big enough hexagon tool to open it. I searched homebase, B&Q and did not find any. Do you know is there a speicially big hexagon tool to open such a valve? Please see the attached picture.



Thanks in advance

Ann

Hi Anna, if my memory serves me right i think you flick the little round cap off at the front middle, then undo screw and start pulling dials off and dismantling.

I wonder if a universal rad valve spanner would do the trick?
