Common Causes of a Dripping Faucet

Most faucet leaks are caused by worn-out or damaged internal components. Over time, washers, O-rings, and seals inside the faucet can degrade due to friction, mineral buildup, or simple age. In cartridge and ceramic disc faucets, the cartridges or seals may fail and allow water to trickle out even when the handle is off. Corrosion or improper installation can also contribute to persistent dripping.

Worn-out washers and O-rings are the most common culprits
Corroded valve seats can cause leaks at the spout base
Loose or damaged faucet parts lead to inconsistent water shutoff
Mineral buildup and high water pressure accelerate wear

How to Fix a Dripping Faucet

Fixing a dripping faucet usually involves disassembling the fixture, identifying the faulty component, and replacing it with a matching part. For compression faucets, this often means replacing washers or seals. For cartridge or ceramic disc models, you may need to replace the entire cartridge. Make sure to turn off the water supply before beginning any repair work. If you’re unsure of the faucet type or repair method, it’s best to call a professional to prevent further damage.

Identify the faucet type: compression, cartridge, ceramic disc, or ball
Replace worn washers, cartridges, or O-rings with the correct parts

When to Call a Professional

While some faucet repairs can be DIY-friendly, others may require professional attention—especially if the leak persists after replacing parts, or if the faucet is old and corroded. If the leak is tied to water pressure issues, deep corrosion, or faulty plumbing beneath the fixture, a licensed plumber can provide a more permanent solution.

Persistent leaks after DIY repairs may indicate deeper problems
Hard-to-reach fixtures or outdated plumbing may need expert help
Professional repairs prevent water waste and costly damage
Upgrading old faucets can improve efficiency and performance

The Cost of Ignoring a Dripping Faucet

A single dripping faucet can waste up to 3,000 gallons of water per year, according to the EPA. Beyond the impact on your water bill, constant dripping can stain sinks, promote mold or mildew, and wear down fixtures faster. Addressing the issue early can save you money, prevent water damage, and reduce your environmental footprint.
