How Does a Simple Tap Work
If you want to know how to repair a leaking kitchen tap, then understanding how your tap operates is key to resolving issues more efficiently. Household taps primarily consist of a valve controlling water flow and a washer or ceramic disk. Some taps use washers, while others opt for ceramic disks. A quarter or half-turn rotation often indicates the use of ceramic disks. When you turn on the tap, it lifts the washer from the valve, allowing water to flow; turning it off tightens the washer, stopping water flow. This grasp of the operation empowers you to diagnose and address issues, ensuring your kitchen tap works smoothly. While tap designs may vary, the fundamental principles remain consistent. Design differences mainly pertain to aesthetics and style.
- Handle or Knob: The tap has a handle or knob that you can turn to control the flow of water. When you turn the handle, you are essentially adjusting the internal components that allow water to flow or stop.
- Valve: Inside the tap, there is a valve that controls the flow of water. When the handle is turned, it either lifts or lowers the valve. There are different types of valves, such as rubber washers or ceramic disks, used in various taps.
- Water Supply: Behind the wall or under the sink, there are water supply pipes that connect to the tap. These pipes carry water to the tap when it is turned on.
- Spout: The spout is the part of the tap from which the water flows. When the valve is opened, water is allowed to pass through the spout and exit into the sink or basin.

How to Repair a Leaking Monoblock Kitchen Tap
What is a Monoblock Kitchen Tap
Monobloc taps are a popular choice. They feature a single spout and a single lever or two separate handles to control both hot and cold water. They are easy to install and provide a streamlined, contemporary look.

Leakage from Monoblock Tap Spout
Spotting a leak in your monoblock kitchen tap is quite easy – you’ll likely hear that annoying, constant dripping sound into your sink. It can be pretty frustrating. If you see your tap still dripping when it’s supposed to be fully closed or if it makes a strange vibrating noise when you turn it on, the problem is often because the ceramic disk cartridge inside is worn out. If you don’t fix it soon, the issue can get worse over time.
To deal with this problem, you must first turn off the water supply at the stopcock or the closest shut-off valve before you start any repairs. To get to the ceramic disk, you’ll need to take your tap apart carefully. When you put in new parts, make sure they’re the same size as the old ones to ensure a proper fit.
Also, be on the lookout for worn O-rings, as they can also cause leaks. If you spot one that’s worn out during your inspection, it’s a good idea to replace it promptly. This will help keep your monoblock kitchen tap working well and prevent any more leaks.
Leakage from Monoblock Tap Handle
