Review: Be careful to measure your old fittings. - There is a warning just below the description on the item that they are a frequently returned item. Careful measurement is required to make sure they will fit. Luckily, I have a vernier gauge that allowed me to get the exact measurements of the old fittings. Thankfully, the measurements were correct and these fit like a glove. My old taps could not be fully turned off and these solve that problem. The is very little travel when turning but they work as expected. Would recommend.
Review: Affordable price - Good quality material fast delivery good affordable price

- Hot and Cold Pair - Supplied as a pair for hot and cold tap repairs; confirm the opening direction and handle fit against your removed cartridge before installation.
- Brass and Ceramic Build - Brass valve body with ceramic discs for everyday sink and basin repairs, suitable for hot or cold water when the dimensions match your tap.

## Questions & Answers

**Q: WHICH TAPS IS THIS VALVE COMPATIBLE WITH?**
A: This valve is compatible with many taps, such as Franke Zurich, Franke Corinthian Filterflow, Franke Athena, Franke Danube, Franke Filterflow Zurich, Franke Helena, Franke Lugano, Franke Moselle, Franke Rialto, Franke Verona and so on.

**Q: HOW DO I KNOW IF I NEED REPLACEMENT VALVES OR A SEAL KIT FOR MY TAP?**
A: If your tap is leaking from the spout (where the water flows out), you’ll need replacement valves. However, if the leak is around the body of the tap, it’s likely the seals (also called O-rings or washers) that need replacing.

**Q: ARE SEALS AND O-RINGS THE SAME THING?**
A: Yes, they are. These components sit between the tap's spout and its body. Over time, they wear out, which is why your tap might leak around the body.

**Q: IF I KNOW WHICH VALVE NEEDS REPLACING, CAN I BUY A SINGLE HOT OR COLD VALVE?**
A: Absolutely! We offer valves as individual units, as well as in pairs.

**Q: ARE THERE ANY TIPS FOR ENSURING A SMOOTH INSTALLATION WHEN REPLACING TAP VALVES?**
A: Yes! One useful tip is to keep a dry paintbrush nearby. Before installing, use the brush to clean the handle cavity and body of the tap. This helps remove debris like limescale, which could otherwise interfere with the handle fitting properly.

### ⭐⭐⭐⭐⭐ Check direction before fitting!
*by P***T on 6 April 2026*

I replaced my cold tap, reassembled everything and only then discovered that the cold one of this pair is anti-clockwise and I needed clockwise. Fine, I took everything apart again and used the hot one from this pair instead - which is clockwise-opening. I wish I had checked first rather than assuming that cold always equals clockwise. Other than that, these did the job. No more drips from the cold tap.
