The Franke Doric kitchen tap is known for its elegant design and durable construction. However, like many mixer taps, its performance can diminish over time, particularly due to worn-out cartridges. A faulty cartridge can lead to issues like dripping, poor temperature control, or stiff operation. Replacing the cartridge in a Franke Doric tap is a straightforward task for most homeowners and can restore your tap to smooth working condition. This guide explores the process of Franke Doric cartridge replacement, offers practical advice, and highlights key points for those seeking long-term performance from their kitchen fixtures.
Understanding the Franke Doric Tap
Key Features of the Doric Model
The Franke Doric tap is a traditional-style mixer tap commonly found in both classic and contemporary kitchens. Its distinguishing features include:
- High-arching spout for enhanced sink accessibility
- Dual-handle control for hot and cold water
- Chrome or brushed steel finish
- Durable ceramic disc cartridge system
Over time, the internal ceramic cartridges can become worn due to limescale buildup or general usage, necessitating a replacement to maintain performance and prevent leaks.
Signs You Need a Cartridge Replacement
Identifying when it’s time to replace the Franke Doric cartridge is essential. Below are some of the most common signs:
- Water dripping from the spout even when the tap is off
- Difficulty turning the handle or jerky movement
- Unbalanced water temperature control
- Reduced water pressure from one or both sides
If your tap exhibits any of these symptoms, replacing the cartridge may resolve the problem efficiently without the need for a complete tap replacement.
Tools and Materials Needed
Before starting the Franke Doric cartridge replacement process, gather the following tools and supplies:
- Replacement Franke Doric cartridge (make sure it matches your tap model)
- Allen key (usually 2.5mm or 3mm)
- Adjustable spanner
- Flat-head screwdriver
- Soft cloth or towel
- Silicone grease (optional)
Ensuring you have the correct replacement cartridge is crucial. Check the tap’s model number or consult Franke’s official product catalog for compatible parts.
Step-by-Step Replacement Guide
1. Turn Off the Water Supply
Start by turning off the water supply to the kitchen tap. You’ll usually find isolation valves under the sink. Turn them clockwise to shut off the flow. Then, open the tap to release any remaining water in the system.
2. Remove the Tap Handles
The Franke Doric tap has two handles hot and cold. Use an Allen key to unscrew the small grub screw located beneath each handle. Once the screws are loose, gently pull the handles off the body.
3. Expose the Cartridge Housing
With the handles removed, use a flat-head screwdriver to lift off the chrome cover or collar surrounding the cartridge housing. Be gentle to avoid scratching the finish.
4. Unscrew and Remove the Cartridge
Use an adjustable spanner to loosen the retaining nut holding the cartridge in place. Once the nut is removed, you can pull out the cartridge. If the cartridge is stuck due to scale buildup, carefully wiggle it out or use a descaling solution to loosen it.
5. Install the New Cartridge
Take the new Franke Doric cartridge and align it properly with the grooves inside the tap body. Gently press it in until it’s seated. Then, screw the retaining nut back into place and tighten with the spanner. Avoid over-tightening to prevent damaging the cartridge.
6. Reassemble the Tap
Place the chrome collar or cover back on the tap. Reattach the handles and tighten the grub screws using the Allen key. Make sure the handles turn smoothly without resistance.
7. Turn On the Water Supply
Turn the isolation valves counterclockwise to restore water flow. Open the tap and test both hot and cold functions. Check for any leaks around the handles or base. If the tap operates smoothly and there are no drips, the replacement was successful.
Maintenance Tips for Long-Term Performance
To extend the life of your new Franke Doric cartridge, follow these simple maintenance tips:
- Regularly clean the tap with a soft cloth to avoid mineral deposits
- Use descaling agents occasionally if you live in a hard water area
- Avoid excessive force when turning handles
- Lubricate internal parts lightly with silicone grease if stiffness returns
Preventative maintenance ensures your tap remains efficient and helps delay future cartridge replacements.
Why Choose Original Franke Cartridges
While there are many third-party cartridges on the market, using genuine Franke parts is highly recommended. They are engineered to match the original specifications of your tap, ensuring a better fit, smoother operation, and longer service life.
Non-original cartridges may be cheaper, but they can wear out faster or fail to seal properly, leading to further issues like leaks or uneven temperature control. For peace of mind, always opt for authentic Franke Doric replacements.
Common Mistakes to Avoid
During a Franke Doric cartridge replacement, avoid these common errors:
- Forgetting to turn off the water supply before starting
- Using excessive force when removing or installing parts
- Mixing up hot and cold cartridges make sure to match each side correctly
- Skipping lubrication, which can lead to stiff operation later
- Not tightening the retaining nut securely, which may cause leaks
Being patient and methodical during the process helps avoid damaging the tap or the new cartridge.
Replacing the cartridge in a Franke Doric tap is a manageable DIY project that can save time and money compared to hiring a plumber or replacing the entire fixture. With the right tools, a compatible cartridge, and a bit of care, your tap can be restored to perfect working order in less than an hour. Regular upkeep and using genuine parts will ensure your Franke Doric tap continues to deliver both functionality and style for years to come.
