What is a mixer tap?

Mostly you might just know it as a tap, but mixer taps are standard features in countless renovated houses and new homes.

In general, mixer taps possess one faucet with one tap handle. There is one handle to control both the cold and hot water, and it shares the same spout. A mixer might be something with one spout and two handles.

The mixer taps are versatile, like a single lever, pull-out or monobloc, and wall mounted. The mixers are regularly found in the bathroom and kitchen sink, including the shower, bathtub, and basin.

Rather than the traditional tap washer, there is a ceramic cartridge with two discs present inside. The upper disc moves with the handle, whereas the bottom disc is fixed, letting the flow of water.

As compared to rubber washers, ceramic disc cartridges are long-lasting; however, they are susceptible to leaks and cracks.

Where is the Tap washer located?

In general, a tap comprises two main parts, the tap washer and the seat. The washer is moved towards the seat and creates pressure when the tap is turned on.

Unluckily, the tap washers are not durable and cause a leaky tap. Due to wear and tear, if the washer is unable to build an airtight seal, a very little amount of water will be permitted to move in and out of the spout.

The change of washer will help you to avoid any sort of leakage.
