What Are the Causes of a Loose or Wobbly Faucet?

It can be very annoying to work with a wobbly kitchen faucet. Even after carefully adjusting the handle, the water can still come loose. There are several reasons why this happens.

Loose Screws

The head and base of a kitchen sink are held in place using a loose bolt under the sink. When the nuts that hold the bolt come loose, the faucets will become wobbly.

Loose Faucet Base

Excessive use can cause the handles of the faucets to loose, which can cause a loose base and a leaky tap. It can also cause the water lines to break.

Worn-out- O-rings

The O-rings are to secure the kitchen sink handles in their proper position. After a while, these O-rings can start to wear out, and this can cause the tap to become wobbly.
