I'm trying to remove my thermostatic valve from my shower unit and the top of the valve has a hex head with notches in it (see photo), i can't get a spanner or regular socket over it, is there a special tool available to remove this?
Yes, i was thinking of the spindle going through the socket, but i guess a longer one would do it, i"ll have to look out for one that long. Just thought there must be a specific offset spanner type tool for this kind of thing.
