Cartridge Maintenance 

We advise that the TMV is regularly 

serviced in hard water areas to 

maintain the flow of water.

Isolate both hot and cold water 

supplies to the mixer tap 

Pull both shrouds away from the wall 

surface to expose the filters. Isolate 

both water supplies to the mixer by 

unscrewing the filters fully, using a 

10mm hexagonal key until there is 

resistance.  Stop using the key at this 

point and use fingers to “wiggle” the 

filter out.

NOTE:

  Turning the hexagonal key 

too far may result in seizing of the 

filters.

1. Remove the control handle lever. 

remove the cap and undo the screw 

and remove the lever.

2. Unscrew the cartridge nut anti-

clockwise using a 30mm socket and 

remove the cartridge from the TMV 

body.

3. Place the cartridge in a suitable 

solution until the cartridge is fully  

de-scaled. Rinse thoroughly with 

clean water to remove any debris.

4. Grease the seals with a  

WRAS approved silicon grease  

and carefully refit the cartridge.

5. Replace the lever handle, tighten 

the grub screw and push-fit the cap 

into position.
