## Description

Review: Solid build, fits well, and no more water dripping - This is the third time I purchased this item over years therefore I am a repeated buyer. The cold side of the water tap start dripping which shows a signal that it is time to replace the valve cartridge. Due to previous experience, it is easy to replace and only takes me 15 minutes to complete it. The valve cartridge is solid build and the size I ordered is compatible with my water tap. Price is reasonable.
Review: Good quality Item(please note these are handed for rotation/position, pls read my review details ) - Very good item, works perfectly with no drips nor leaks. the rubber seals can withstand the cold water tap pressure here so I am quite happy. Pleased with the quality and the price and it was easier than having to go to howdens in person for a replacement - delivered to the door - I believe this should be noted in the review as a positive point as it is a factor in the purchase of this product I would advise that these are handed so they come in a set and you can't swap them from hot and cold to cold and hot - as the rotation of the tap design means the cold one turns anti clockwise to turn on and the hot turns clockwise. I dont believe that the seals alone can be replaced so buying these was the best option to stop the very annoying drip drip drip of the old one LoL

## Questions & Answers

**Q: How do I know if this cartridge fits my kitchen tap?**
A: Please count the number of teeth on the spline (the top part that fits into the handle). Our cartridge is designed to be a compatible replacement for various premium kitchen taps that require this specific 28-teeth configuration.

**Q: Is this compatible with high-end European brand taps like the Ascona series?**
A: This valve is specifically engineered to be compatible with 28-teeth spline models often found in high-end kitchen tap series. We recommend checking your original part's dimensions and tooth count to ensure a great fit before ordering.

**Q: What is the material of this replacement valve?**
A: Our cartridges are made of high-quality solid brass and ceramic, ensuring durability and a leak-free experience. The 28-teeth design provides a precise and secure connection for your tap handle.

**Q: Does it come with the necessary screws for installation?**
A: Yes, each 28-teeth cartridge comes with a matching M4 screw to ensure you have everything needed for a quick and easy replacement process.

**Q: What should I do if the handle is still loose after installation?**
A: A loose handle usually means the tooth count doesn't match. Please double-check that your tap requires a 28-teeth spline. If you have the correct 28-teeth handle, our precision-machined spline will provide a tight, wobble-free fit.
