My shower head's leaking problem is getting worse. I tried to reomve the shower handle to get access to.the mixing cartridge but unable to do so.
I couldn't locate the fixing crew. I tried to pull on the handle, turn the handle clockwise and conter clockwise. Nothing happened as well (I didn't dare to use too much force).
I also tried to use a crew driver and a knife to prime on the gap shown i the photo, couldn't move it
