A dripping faucet may seem like a small problem, but over time it can waste a surprising amount of water and become increasingly annoying. In many cases, the cause is a worn or damaged part inside the faucet.
Before attempting a repair, first determine where the water is coming from and whether you can safely access the faucet components.
1. Make Sure the Faucet Is Completely Off
Turn the faucet handle to its normal off position without forcing it.
If water continues to drip from the spout, an internal component may no longer be creating a proper seal.
Do not overtighten the handle in an attempt to stop the leak, as this can damage the faucet.
2. Check Around the Faucet
Not every faucet leak comes from the spout.
Look for water around:
- The base of the faucet
- The handles
- Under the sink
- Supply line connections
Water appearing around these areas may indicate a different problem than a dripping spout.
3. A Worn Washer or Seal May Be the Cause
Many faucets contain washers, seals, cartridges, or other components that control the flow of water.
These parts can wear out with regular use. When they no longer seal properly, a small amount of water can continue passing through even when the faucet is turned off.
Replacing the worn component often solves the problem.
4. Mineral Buildup Can Affect Faucet Parts
Minerals and debris in the water can accumulate inside a faucet over time.
This buildup may prevent internal components from closing properly and can contribute to dripping or inconsistent water flow.
Cleaning accessible faucet components may help, depending on the faucet design.
5. Turn Off the Water Before Taking the Faucet Apart
If you decide to inspect or replace an internal faucet component, shut off the water supply first.
The shutoff valves are commonly located underneath the sink.
After closing them, turn on the faucet briefly to make sure the water supply has actually stopped before disassembling anything.
When Should You Call a Plumber?
Consider calling a licensed plumber if:
- You cannot identify the source of the leak
- The shutoff valves do not work properly
- Water is leaking underneath the sink
- The faucet or plumbing connections are corroded
- Replacing a simple component does not stop the dripping
- You are uncomfortable taking the faucet apart
A dripping faucet is often caused by a relatively small worn component, but ignoring it can waste water and allow the problem to worsen. Fixing the cause early can prevent a minor annoyance from becoming a larger plumbing repair.
