Simply Build It

Hi,

sounds like a TS1500 shower -
Plastic knob sounds like it has stripped the splines off due to overtightening, the fact that the valve is tight is due to a build up of limescale. Best plan is to strip down the brass body, descale the components in a kettle descaler fluid, replace the o-rings and re-grease with silicon grease. If you don't do this, the knob will fail again (and the dripping will not be eliminated).

If it's anything like my shower, replacing it with a completely new shower unit is a massive job - compared to about £40 worth of spare parts which will give you a shower that performs just like new. Beware that some parts may be difficult to dismantle and may require access to a vice.

I have dismantled this model of shower about three times (mines and a neighbours) and am happy to give further guidance if needed.

Good luck,

Mark.
