our sink hot tap is knackered. i thought it was just low water pressure but all the other taps are fine. the water was just trickling rather than flowing.
i unscrewed the top and had a look and a fiddle with a scredriver and made it a bit worse, as per usual with my diy. the screw just turns round with the tap, rather than turning it on and off and makes a horrid grinding noise.
any ideas? something simple like a new washer or do i need a plumber?
thanks
