Taps will leak or drip from the spout if the ceramic cartridge valve does not completely seal the water flow in full. The main cause of failing to seal the water is debris, and lime scale build up inside the cartridge.
The debris and lime scale build up prevents the ceramic cartridge valve from completely sealing and closing the water flow.
A microscopic gap, not usually visible to the human eye can create a leaking or dripping tap from the spout.
Most ceramic cartridge valve taps operate between 0.5 - 2 bar water pressure, which is enough pressure to cause the water to seep through the microscopic gap and travel up your spout and cause the drip. Usually the higher your water pressure the faster you will need to service your tap.
Due to the hard water in most parts of UK and around the world, taps are mostly designed and fitted with ceramic cartridge vales which are now made in a way so that they are easy to replace or service.
To replace or service the ceramic cartridge valve, please follow these simple instructions below:
- Unscrew the lever or if you have a hot/cold symbol remove the symbol
- Unscrew the grub screw located behind the lever or the hot/cold symbol
- Remove the body of the lever from the tap
- Some models have a chrome cover that covers part of the brass holding nut, this cover will need to be unscrewed
- You will now see a brass holding nut that holds the ceramic valve in place, unscrew this holding nut and clean and replace the ceramic valve back in place.
- You will now need to put it all back together, making sure the valve is firmly tightened by the brass holding nut, make sure it is not over tightened.
If you need to purchase a new ceramic cartridge valve, please contact our support centre with details of your tap and they will advise you on the correct valve you require.
