I have a concealed shower tap and recently when closed water still trickles out. What makes it worse is when another supply is used in the house this tap starts to humm.
I thought I would try and clean the valve or see if I can replace it. I took the know off and came to my first obstacle.
Please see images attached. Do I need a special tool to into the two holes and if so can someone advise what it is called.
I saw some videos about doing this but understand all showers are different. I think my plate is sealed on with some sort of bond too but think there is enough play in the hole for that thing to come out.
Any help would be great.
Thanks in advance
