Bidet hot tap doesn't turn as much

[Sprogginz]

I'm staying at my parent's house while one of them recovers from an operation after a fall.

I noticed the hot water tap on their bidet only turns about three quarters, it's enough to give out a trickle but not to jet wash your backside.



Does anyone know what's probably happened and how to remedy the issue? I've squirted a bit of WD40 and left it a bit but hasn't made much difference if any.

Thanks very much.

Tap innards have failed or possibly just a washer. Might be best doing the 2, new washer and regrease the innards.

Thanks very much. What grease is that, copper?
