The single-handle faucet is one of the most popular types of faucets today. The single-lever mixer is easy to install and use. It combines a hot and cold water tap. The hot and cold water outlet pipe is controlled by changing the direction of rotation of the handle. And the water temperature is controlled by the angle of rotation. This type of faucet is commonly installed in private households today. A single lever faucet can have one of three different types of valve mechanisms, but the maintenance steps between them are not very different. When the faucet leaks, the rubber seal or O-ring is usually worn out, although you may need to remove the faucet for easy replacement. The temperature adjustment problem is more common with cartridge taps and sometimes means you need a new cartridge.

Different types of valves

When repairing a mixer tap, it is helpful to know which machine you are using. Usually, a cursory glance at the tap is enough to get this information. If the bottom of the lever is round or hemispherical, then there is a ball valve on the faucet. However, if the lever is directly connected to the valve stem and there is a round neck around the valve, it can be a ceramic disc. If the valve body is straight and cylindrical and the bottom of the lever pulls the valve up when the lever is lifted, the faucet can contain an ink cartridge.


No matter what type of faucet you want to fix, you need to turn off the water supply and remove the faucet handle. It is usually secured by a hex head screw under the lever. You may have to pry open the decorative cover to find it. After separating the handle, loosen the collar to loosen the ball valve, then remove two or three screws to remove the ceramic disc. The ink cartridge may be more difficult to remove. After pulling out the mounting pin with pliers you should be able to pull it out, but it will often get stuck and you may need to find a cartridge puller to remove it.

Replace the gasket

The seal that causes the leak is usually in the water inlet port at the bottom of the valve seat. You can usually lure them out with a flathead screwdriver, and if they are spring-loaded, the spring comes with them. Most hardware stores have options for repairs to seals and springs, so you should find alternatives. Ceramic discs, ball valves, and coils usually come with external O-rings and can leak even when worn. Use a utility knife to cut off the worn grease, sprinkle the grease on the new grease, and roll the grease to improve the tightness.

Ink cartridge problem

Older ink cartridges can be clogged with mineral deposits. In this case, it can be difficult to adjust the temperature. If you can't scrape off the minerals with a knife or small wire brush, the most common way to dissolve the minerals is to soak the cartridge in white vinegar overnight. However, sometimes the best solution is to simply buy a new ink cartridge, especially if the ink cartridge has cracks or grooves that will cause leaks. Before disassembling the faucet to improve the flow of hot water, don't forget to check the temperature limiter, which is usually a plastic plate under the handle. May need to be adjusted.
