Maintenance & Care
A concealed thermostatic system requires minimal routine maintenance. These guidelines cover daily care, periodic servicing, and cartridge replacement — the only component that will ever need attention in normal use.
Daily & Weekly Care
- Wipe trim plates and handles with a soft damp cloth after each use to prevent limescale and soap residue build-up.
- Use only pH-neutral, non-abrasive cleaners. Avoid bleach, ammonia-based products, and abrasive pads on all PVD and chrome surfaces.
- For limescale on hard water installations, apply a diluted white vinegar solution (1:3 with water) with a soft cloth. Do not soak or spray directly onto the trim plate.
- Dry the trim surface after cleaning to prevent water spotting, particularly on matte black and brushed gold finishes.
Annual Service Checks
- Verify outlet temperature with a thermometer. A drift of more than ±2°C from the set point indicates the cartridge wax element may require replacement.
- Inspect the trim plate seal against the tile surface. Re-apply sanitary silicone if any gap or lifting is observed.
- Check diverter operation across all positions. Stiff or incomplete switching typically indicates mineral build-up on the diverter cartridge — clean or replace as needed.
- In hard water areas (above 200 ppm), consider an inline scale inhibitor on the cold supply to extend cartridge service life.
Cartridge Replacement
The thermostatic cartridge is the only serviceable internal component. Replacement does not require wall access — the entire procedure is completed from the front of the trim plate.
- 1 Isolate the water supply at the service valves (accessible behind the trim plate without tile removal).
- 2 Remove the handle by unscrewing the grub screw (2mm hex key) and lifting off. Remove the retaining nut with a 22mm spanner.
- 3 Pull the cartridge straight out. Note the orientation tab before removal.
- 4 Insert the replacement cartridge, aligning the orientation tab. Hand-tighten the retaining nut, then torque to 20 Nm.
- 5 Refit the handle, restore supply, and verify temperature set point before returning to service.
