Dripping Faucet: What It Costs to Fix and Why It's Worth Doing Now

A dripping faucet seems minor, but it wastes real money over a year. Here's what causes it and what fixing it costs.

What's actually leaking

Most faucets leak from a worn rubber washer, O-ring, or internal cartridge, depending on whether you have a compression, ball, cartridge, or ceramic-disc faucet.

Why it costs you more than you think

A faucet dripping once per second can waste thousands of gallons a year — real money on your water bill for a five-dollar part.

The DIY fix

Shut off the water supply under the sink, identify your faucet type, and swap the matching washer or cartridge. Most repair kits include everything needed.

When it's not DIY

If the leak is inside the wall, or replacing the cartridge doesn't stop it, the valve body itself may need professional attention.

A quick cost guide

Simple faucet repairs typically run at the lower end of a plumber's service call; full faucet replacement costs more but solves recurring issues for good.
