2. Installation Guide
Before beginning installation, ensure you have the correct cartridge for your tap model. The cartridge should have "BS5412 XZ 20" marked on it, and feature a threaded collar with a 32-spline handle adaptor (10mm diameter, 32 teeth).
Required Tools (Not Included):
- Adjustable wrench or spanner
- Screwdriver (flathead or Phillips, depending on tap handle)
- Cloth or towel
Installation Steps:
- Turn Off Water Supply: Locate the main water shut-off valve for your home or the isolation valves under the sink and turn them off. Turn on the tap to drain any remaining water and relieve pressure.
- Remove Tap Handle: Carefully remove the decorative cap (if present) on the tap handle. Use a screwdriver to loosen and remove the screw holding the handle in place. Lift the handle off.
- Remove Shroud/Cover: Unscrew or lift off any decorative shroud or cover that conceals the cartridge. This may require an adjustable wrench if it's tightly secured.
- Remove Old Cartridge: Using an adjustable wrench, carefully unscrew the old tap cartridge. Turn counter-clockwise. Be prepared for a small amount of residual water.
- Clean Cartridge Housing: Wipe the cartridge housing clean with a cloth to remove any debris or mineral deposits.
- Insert New Cartridge: Place the new TML BS5412 XZ 20 cartridge into the housing. Ensure it is seated correctly and the locating pins (if present) align with the slots in the tap body.
- Secure New Cartridge: Hand-tighten the cartridge into place, then use an adjustable wrench to gently tighten it until snug. Do not overtighten, as this can damage the cartridge or tap body.
- Reassemble Tap: Replace the shroud/cover, then reattach the tap handle, securing it with the M4 screw provided. Replace the decorative cap.
- Restore Water Supply: Slowly turn the main water supply or isolation valves back on. Check for any leaks around the tap base and cartridge area.
- Test Operation: Turn the tap on and off several times to ensure smooth operation and proper water flow.
3. Operation
Once correctly installed, the TML BS5412 XZ 20 ceramic disc cartridge provides reliable quarter-turn control for your tap. Turning the handle a quarter of a turn will fully open or close the water flow. For mixer taps, the cartridge facilitates the mixing of hot and cold water to achieve the desired temperature.
4. Maintenance
The TML BS5412 XZ 20 tap cartridge is designed for a long life cycle with minimal maintenance. To ensure optimal performance and longevity:
- Regular Cleaning: Periodically clean the exterior of your tap with a soft cloth and mild soap. Avoid abrasive cleaners or harsh chemicals, as these can damage the tap finish and potentially affect internal components.
- Check for Leaks: Routinely inspect the base of your tap and under the sink for any signs of water leaks. Early detection can prevent further damage.
- Water Quality: In areas with hard water, mineral deposits can accumulate over time. While ceramic discs are resistant, extreme build-up might affect performance. Consider water softening solutions if this is a persistent issue.
5. Troubleshooting
If you encounter issues with your tap after installing the TML BS5412 XZ 20 cartridge, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tap is leaking from the spout or handle base. | Cartridge not seated correctly, damaged O-rings, or overtightened cartridge. | Turn off water supply. Re-check cartridge seating. Ensure O-rings are intact and properly positioned. Avoid overtightening. |
| Tap handle is stiff or difficult to turn. | Cartridge overtightened, mineral deposits, or incorrect handle alignment. | Loosen cartridge slightly (if overtightened). Clean around the cartridge and handle mechanism. Realign handle. |
| No water flow or reduced flow. | Water supply not fully restored, aerator clogged, or cartridge not fully open. | Ensure water supply valves are fully open. Clean or replace the tap aerator. Check if the cartridge is correctly installed and allows full flow. |
| Cartridge does not fit my tap. | Incorrect cartridge model for your specific tap. | Verify your tap requires a BS5412 XZ 20 cartridge with a threaded collar and 32-spline adaptor. Contact the seller for compatibility assistance before purchase. |
