A faucet that drips continuously usually signals a worn seal, valve issue, or trapped debris—not something that resolves on its own. Addressing the problem promptly can prevent water waste, reduce wear on plumbing components, and stop the sound that disrupts daily life.

While the exact fix depends on the faucet type, most dripping stems from one of a few failure points inside the handle and valve assembly. With basic tools and careful inspection, many leaks can be repaired without a plumber.

Start with the right diagnosis

Before disassembling anything, confirm where the water is coming from: the spout (most common), the handle area, or the faucet base. Then note whether the drip changes when you slightly turn the handle, or if it runs only when water pressure is applied.

In many cases, a drip that continues even when fully closed points to a damaged washer, O-ring, cartridge seat, or a buildup of mineral deposits. A leak around the handle can indicate a worn stem seal or cartridge seal, while moisture at the base may reflect gasket failure.

Check for simple fixes first

Some drips are caused by debris or mineral scale. Turn off the water supply, then remove the aerator at the tip of the spout (if your model has one). Rinse the screen and soak the aerator in vinegar to dissolve buildup, then reinstall and test.

If the drip persists, the next step is to inspect the valve internals. Make sure the water is fully shut off before proceeding.

Common repair steps by faucet style

For many compression faucets (typically older two-handle designs), the fix often involves replacing the washer. After removing the handle and stem, check the washer for cracks or flattening, replace it if needed, and reassemble. For cartridge or ball faucets (common in newer models), the issue may be a worn cartridge or O-ring; replacing the cartridge is frequently the most reliable solution.

If you have a single-handle faucet, the cartridge or seal is often accessible after removing the handle and retaining clip. Replace any O-rings or seals showing swelling or wear, and ensure the cartridge seats correctly to stop the drip.

Aftercare and preventing repeat drips

Once repaired, turn the water back on slowly and test by cycling the handle several times to confirm the leak is gone. Clean and lubricate only as recommended for your faucet model—over-lubrication can attract debris.

To reduce recurrence, periodically check the aerator for mineral buildup, especially in areas with hard water. If you’re unsure about the faucet model or the parts you need, consult the manufacturer’s guide or match replacement components by the faucet’s brand and serial information.

If the faucet still drips after a proper internal repair, it may be due to damaged seats, a warped valve, or a plumbing leak downstream of the faucet. In that case, a licensed plumber can diagnose the source quickly and prevent further water loss.
