Anything that is moved frequently, regardless of its makeup, relaxes over time. Metals, plastics, composites will wear out a bit with routine use. This is true for kitchen faucets, for example. A loose faucet can be caused by a worn-out O-ring or a wobbly faucet base. Whether it’s cold or hot water you need, the knobs will become a bit loose over time. In this informative article, we will take a look at loose kitchen faucets, which have a dual function, so to speak, and then give you instructions on how to tighten kitchen faucets.

There are usually two types of problems affecting the faucet when it is loose. The base of your faucet may have loosened over time as water circulates through it and this is to deal with water pressure. Another problem is with the handle. It loosens on overuse. Every time you flip the handle to control the water flow, there will be a little loss of tightness. For this reason, our guide will be divided into two sections: tightening the base and the handle.
