How to Fix a Faucet That Drips After Turning Off

A faucet that drips after you turn it off usually has a worn seal, washer, cartridge, or seat inside the faucet, not a supply-line problem. First, check whether you’re seeing leftover water in the spout or a drip that keeps coming back after shutoff. Then match the repair to the faucet type before you take anything apart.

Is it just leftover water or a real drip?

A few drops right after shutoff can be trapped water draining from the spout or aerator. That’s usually not the same as a leak.

A real drip keeps coming after the handle is fully closed, especially if it starts again after a short pause or continues minutes later. If the faucet stops quickly and doesn’t return, you may only have residual water. If it keeps dripping, the problem is usually inside the faucet rather than at the spout.

Look at the pattern before you open anything. If the drip is tied to one handle position, the handle feels loose, gritty, or unusually stiff, or the faucet only stops leaking when you wiggle the handle, that points to an internal seal or cartridge issue.

Identify your faucet type in under a minute

The repair depends on the faucet style, so identify that first. One handle or two helps, but the handle feel and body shape matter too.

• Compression faucet: Usually has separate hot and cold handles. The handle often turns with noticeable resistance and keeps turning as it closes.
• Cartridge faucet: Often has one handle, though some have two. The handle usually moves up and down or side to side on a cartridge.
• Ball faucet: Common in single-handle kitchen sinks. The handle moves over a rounded cap, and the faucet often has more small internal parts.
• Ceramic disk faucet: Often a single-handle design with a very smooth feel. These usually use a ceramic disk cartridge inside.

If you can’t tell by looking, remove the handle trim and inspect the stem or cartridge shape before buying parts. That’s usually faster than guessing and ending up with the wrong repair kit.

Before you take anything apart

Start with the reversible checks first. Fully close the faucet, then watch whether the drip stops after a minute or two. If the flow changes when you move the handle a little, that’s another sign the problem is inside the faucet.

Check the shutoff valves under the sink and make sure they turn normally. If they don’t close, or if you need to disassemble the faucet, shut off the water at the supply shutoff first. Open the faucet briefly after shutting the supply off to bleed off trapped pressure, then close it again before you start removing parts.

Protect the sink with a towel or stopper, and plug the drain so small screws, springs, or seals don’t disappear.

What usually fails in each faucet type

Here’s the quick match between faucet style and the part that usually causes a drip after shutoff.

A compression faucet often drips because the washer no longer seals against the seat. A cartridge faucet often needs a new cartridge or O-rings. A ball faucet commonly needs seat and spring parts, and a ceramic disk faucet usually points to a damaged or dirty cartridge rather than a simple washer.

Mineral buildup can make a good-looking part fail by keeping it from seating fully.

Clean, reseat, or replace the worn part

Start with the least invasive fix. If the part is only dirty or lightly mineral-coated, clean it and reseat it. If the rubber, plastic, or sealing surface is worn, torn, flattened, cracked, or hardened, replace it instead of trying to save it.

For a compression faucet, remove the handle and stem, then inspect the washer and seat. Portland’s repair steps show removing the handle, then loosening the packing nut to reach the stem. iFixit notes that many leaky compression faucets need new seat washers and that the water supply should be cut off before disassembly. If the washer is damaged or loose, replace it. If the seat is rough or pitted, clean it lightly or replace it if your faucet design allows that.

For a cartridge faucet, remove the handle and take out the cartridge. Check for grit, mineral scale, and damaged O-rings. Clean the cartridge and body if debris is the only problem. If the cartridge still drips after cleaning, replace it rather than trying to patch the seals.

For a ball faucet, inspect the seats and springs first. Those small parts are common failure points, and debris or scale can keep the ball from sealing. Clean the ball and body carefully, then replace the seat and spring set if the sealing surfaces look worn.

For a ceramic disk faucet, clean away mineral buildup around the cartridge and inspect the seals. If the faucet still drips after cleaning, replace the disk cartridge as a unit if that is how your model is built.

Keep the parts in the order they came out, especially if you’re working on a cartridge or stem assembly. Reversed parts or a missed seal can create a new drip or make the handle feel wrong when you put it back together.

Put it back together and test for a clean stop

Reassemble in the reverse order you took it apart, and seat each part gently. Thread screws and nuts by hand first so you don’t cross-thread them, then tighten only enough to secure the parts. If the packing nut or trim is overtightened, the handle can bind or the seal can distort.

Restore water slowly at the supply shutoff. Open the faucet carefully and watch the stem, handle base, and spout for leaks before you fully open the water. Portland’s repair steps end with turning the water back on and watching for leaks.

Let the faucet run briefly, then shut it off and watch the spout. A clean repair should stop dripping at once or after only a small amount of trapped water clears. If the faucet stops for a few seconds and then starts again, debris may still be inside the valve body or the wrong part may have been replaced. Check the handle area too; a new leak at the base usually means a seal, nut, or cartridge was not seated correctly.

When the faucet is past repair

If the valve body is badly corroded, the seats are pitted beyond cleanup, or the same faucet keeps failing after fresh parts, replacement is usually the better answer. Repeated drips after correct repairs often mean the body itself is worn, not just the washer or cartridge.

Replace the faucet if the stem is stripped, the cartridge won’t stay seated, or the trim and internal parts no longer match a repair kit. Call a plumber if the shutoff valve won’t close, a supply line starts leaking, or the faucet body is too damaged to reassemble without forcing parts. At that point, another patch usually costs more time than it saves.
