I'm trying to change the diverter valve in my bath/shower tap but I cannot get the key out to enable me to do so. Does anyone have any ideas on how to remove it? I'm also not sure what it's called, but it's the U shaped key that holds the valve in?
It is a Grohe Concetto (25109) tap, and the part I'm trying to replace is diverter valve (48035).
Thanks in advance!
