How to fix a dripping tap
If you don’t repair a leaky tap, it can waste over 4 litres of water per day. In this post, learn how to fix a dripping mixer tap, an environmentally-friendly and cost-effective process.
If one drop were to fall every second, this would waste 4.32 litres of water per day, or 1,577 litres per year. Leaks and drips from our bathroom taps can waste water but are easy to avoid, simply by ensuring good tap maintenance.
One of the main problems is when our taps start to drip. And to fix a leaky mixer tap, whether it’s in the bathroom or kitchen, you will probably need to replace the ceramic cartridge inside with a new one.
Noken cartridges work using ceramic disks which collect water, open and close the supply, regulate flow and temperature. They are found inside the tap and supply mixed water.
To change a mixer tap cartridge and fix a leak, you will need…
- An adjustable wrench
- An Allen key
- A new cartridge
How to fix a dripping tap, step by step: Firstly, you should shut off the water supply
- Remove the tap’s decorative cover by hand, which hides the hole through which we can access the screw to remove the single handle.
- Loosen the handle set screw with an Allen key and remove the tap’s handle.
- Remove the mixer tap cartridge's decorative cover.
- Loosen the cartridge locknut using a large adjustable wrench, and finish loosening it by hand.
- Remove the old cartridge, paying attention to the position. Install a new ceramic tap cartridge, lining up the water outlets correctly and checking that it is properly fastened.
- Replace the locknut and tighten it by hand. Finish by tightening it with the wrench.
- Replace the cartridge's decorative cover and the tap handle. Tighten the set screw to fasten it and replace the decorative cover.
- You can now switch the water supply back on, and check that you have fixed the dripping tap.
If the water flow is irregular, you might also need to clean and change the tap aerator. As we explained in this post, aerators are easy to install and no professional assistance is required. They are simply screwed into or unscrewed from the opening of the spout. To remove particles of dirt, grit or limescale that may obstruct the flow of water and reduce the tap’s efficiency, you just need to remove it and immerse it in vinegar.
