A faucet that drips once per second wastes 3,000 gallons of water per year. The fix depends on the faucet type. Here's how to identify and repair each.
Before you start: shut off the water supply
Turn the shut-off valves under the sink clockwise to close. If valves are absent or seized, shut off the main. Turn on the faucet to release remaining pressure before disassembling.
Cartridge faucets (most common)
Most single-handle kitchen and bathroom faucets use a cartridge. Remove the handle screw (usually under a decorative cap), pull the handle off, unscrew the cartridge retainer, and pull the cartridge straight up. Take it to a hardware store to match the replacement. Installation is the reverse process.
Ball-style faucets (single-handle with a ball inside)
These have a rotating ball that controls hot/cold mixing. They wear faster and require a repair kit ($15–$20) that includes a new ball, springs, seats, and O-rings. Remove the handle and cap, extract all worn components, and install the full kit.
Compression faucets (older two-handle)
Each handle has a rubber washer at the bottom of the stem that presses against a seat to stop flow. Remove the handle, unscrew the packing nut, and pull the stem. Replace the rubber washer at the bottom ($1) and reassemble.
When to call a handyman
If the shut-off valve won't close, the valves are corroded, or cartridge matching is unclear, it's faster to call a pro. Faucet repair and replacement starts at $65 at The Toolbox Pro.
Frequently Asked Questions
How do I stop a dripping faucet?
Identify the faucet type (cartridge, ball, or compression), shut off the water supply, disassemble the handle, and replace the worn cartridge or washer. Most repairs take 30–60 minutes.
What causes a faucet to drip?
Worn internal components — cartridges, washers, O-rings, and ball valves — degrade over time. Hard water accelerates wear. Most faucets need service every 10–15 years.
How much does faucet repair cost?
Faucet repair or replacement at The Toolbox Pro starts at $65. If the faucet itself is damaged beyond simple repair, full replacement is often the same price.
Can I fix a dripping faucet myself?
Yes, if you're comfortable shutting off water and disassembling a handle. Cartridge faucets are the easiest. Ball-style faucets require a repair kit.
Is it cheaper to repair or replace a leaky faucet?
Repair is cheaper if the faucet body is in good shape. If the faucet is 15+ years old or the finish is worn, replacement with a new model often makes more sense economically.
