Ball Faucet Parts: How a Ball Faucet Works

Faucets parts of a sink unit come in quite a few varieties. Among all of these options is the humble but brilliant ball faucet. A ball faucet is part of a mixer faucet and the ’ball’ is the main way the faucet operates.

Closer Look

Let’s take a closer inspection of how a ball faucet works. Across the top of your sink will be the holding base which attaches under the sink unit to keep the faucet tight and steady. Attached to this is the spout pipe which flows directly to the faucet's aerator. The parts you don’t see from the outside are the springs and seats upon which the metal ball sits. The metal ball is a rotational device which allows you to set the direction, pressure and temperature of the water by rotating the handle on which it is fixed. The metal ball is located and fixed in place by a cam, to which the handle screw attaches.

How does it work?

Think of it as a ball joint like your shoulder or hip. When you want to turn on your faucet you first decide whether you need cold or hot water. So, you grab the handle and pull it in the right direction toward hot or cold. After you do this you won’t want the water to come rushing straight out and shower you, so you tip the handle down a wee bit to lower the pressure of exiting water. This is where the ball faucet comes into play. The ball regulates the amount of water according to the way you position the handle.
