Faucet handles can loosen over time due to use and wear. Sometimes, you may not even notice that the faucet has slipped off its track until it’s too late. The water isn’t flowing properly and you could end up with a flooded bathroom, which is an expensive repair.

When tightening a loose faucet handle, you should tighten the set screw or the handle screw. The set screw is located inside the handle and holds it securely in place. If a set screw is loose, turn it counter-clockwise to tighten it. If there is no set screw, tighten the faucet handle by turning its knurled knob to tighten it.

The Retaining Nut Is Loose

A loose retaining nut is the reason that a faucet won’t be able to turn or will leak. The retaining nut is one of the most important parts of a faucet because it holds the faucet handle in place. It can also be called a set screw and is usually located on the underside of the handle.

If you notice that your faucet isn’t turning, it could be because there is no retaining nut holding it in place. Make sure to check for this problem frequently, especially if you use your water frequently or have small children around.
