Leaking Thermostatic Shower

[Callum098]

Hi there, very new to the forum. Seen some very helpful information floating around on here, however I think I need more specific help if possible.

Dropped some pictures below of exactly where the water seems to be coming from. The nut which tightens to bar part of the shower, this is the temperature control side of the shower. It was and still is very stiff to turn the temperature. It's always been this way, however after turning it recently we've noticed there's now a consistent stream of water coming from the nut.

Any advice would be greatly appreciated.

suggest
1. Isolate hot and cold supplies.
2. Disassemble the overhead section
3. Use fairly large adjustable to loosen the 2 big nuts, each bit by bit.
4. the unit will come away from the wall suddenly and is quite heavy, put a towel under it to protect the shower tray if you drop it
5. Install 2 x new "3/4 flat rubber washers with metal gauze filter" in place of the old ones.
6. reinstall and reassemble

- this should fix the leak, but while you have the unit away from the wall, remove the "button" out of the centre of the temp control knob, undo the philips screw then look underneath the unit and there will be a screw head or allen - undo, remove the cartridge (pulls out)

Go to shower doc website and order new thermostatic mixer cartridge
