Safety Information
- Always turn off the main water supply to your property before attempting any plumbing work.

Package Contents
Upon opening the package, please verify that all components are present and undamaged:
- 1 x TML MV01 Ceramic Cold Replacement Tap Cartridge (20 splines)
- Installation Instructions (if provided by manufacturer)
Setup and Installation
Follow these steps carefully to replace your tap cartridge:
- Turn off Water Supply: Locate the main water shut-off valve for your property or the isolation valve for the specific tap and turn it off.
- Drain the Tap: Open the tap to drain any residual water from the pipes.
- Remove Tap Handle: Carefully remove the tap handle. This usually involves unscrewing a small grub screw (often hidden under a decorative cap) or simply pulling the handle off if it's a push-fit design.
- Remove Shroud/Cover: If present, remove any decorative shroud or cover that conceals the cartridge.
- Unscrew Retaining Nut: Using an adjustable spanner or appropriate wrench, carefully unscrew the large brass retaining nut that holds the old cartridge in place. Turn counter-clockwise.
- Remove Old Cartridge: Lift out the old ceramic cartridge. Note its orientation.
- Clean Housing: Clean any debris or limescale from the cartridge housing within the tap body.
- Insert New Cartridge: Place the new TML MV01 cartridge into the tap body, ensuring it is correctly seated and aligned with any locating pins or grooves. This cartridge is specifically for the cold water side.
- Secure New Cartridge: Hand-tighten the retaining nut back onto the tap body, then use the spanner to gently tighten it. Do not overtighten, as this can damage the cartridge or tap body.
- Reassemble Tap: Reattach any shrouds/covers and the tap handle.
- Restore Water Supply: Slowly turn the main water supply back on.
- Check for Leaks: Open the tap and check for any leaks around the base of the tap or where the cartridge is seated.

Operating Instructions
Once installed, the TML MV01 cartridge operates identically to your original cold water cartridge. Simply turn the tap handle to control the flow of cold water. The ceramic disc mechanism ensures smooth operation and a drip-free seal when closed.
Maintenance
The ceramic cartridge is designed for long-lasting performance with minimal maintenance. To ensure its longevity:
- Avoid overtightening the tap handle, as this can put undue stress on the ceramic discs.
- If your water supply has high mineral content, consider installing a water softener to prevent limescale buildup, which can affect cartridge performance over time.
- Periodically check for any signs of dripping or reduced flow, which may indicate wear.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tap is still dripping after installation. | Cartridge not seated correctly, retaining nut not tight enough, or debris in the tap body. | Turn off water, re-check cartridge seating, gently tighten retaining nut, and ensure no debris is present. |
| Reduced water flow. | Aerator clogged, or partial blockage in the water supply line. | Clean or replace the tap aerator. Check water supply valves are fully open. |
| Tap handle feels stiff. | Overtightened retaining nut or mineral buildup. | Slightly loosen the retaining nut. If due to mineral buildup, consider professional cleaning or replacement. |
