5 Common Causes of Leaking Faucets

A leaking faucet may appear to be a minor issue. However, if it isn’t repaired, it can create a number of problems in your home. Plumbing leaks waste water, increase your water bill, and can cause water damage to your home if left unaddressed. That’s why it’s important to fix a leaking faucet before it becomes a bigger, more expensive plumbing repair. Common causes of leaking faucets include:

5 Common Causes of Leaking Faucets



A faucet’s handle is typically attached with a stem screw. The rubber O-ring attaches to the screw to prevent leaks. O-rings will wear out over time. An old, worn-out O-ring will cause the faucet to leak near its handle. Replacing the O-ring should eliminate the leak.


Like O-rings, metal washers prevent leaks by sealing gaps between your faucet and your pipes. Washers will also become worn out over time. When your washers become worn, your faucet will leak. Incorrectly installing a washer, or using a washer that is not the correct size, will also cause a leak.

Broken Fittings and Pipes

If you have a leak underneath your sink, it may be caused by a broken fitting or a broken pipe. You will probably need help from a professional plumber to repair the leak.

Corroded Valve Seat

The valve seat is the connection between your sink’s spout and faucet in the compression mechanism. Sediments can build up over time and cause the valve seat to become corroded, which creates leaks. Have a plumber clean your valve seat regularly to prevent corrosion.

Water Pressure

If your faucet only leaks at certain times of the day or when the handles are in a specific position, it could be the water pressure that’s causing the problem. Have your plumbing system inspected by a DFW plumber if you’re concerned about your water pressure.
