10 Reasons Your Kitchen Faucet Won’t Stop Dripping (And How to Fix It)

You know that sound. It’s 11 PM, the house is quiet, and then you hear it from the kitchen. Drip. Drip. Drip. It doesn't sound like much at first, but that tiny rhythm can drive you crazy and waste gallons of water. If you live in Clarksville, TN, you know our local water can be a bit tough on fixtures. Over time, those minerals build up and turn a smooth-running faucet into a leaky mess.

Here’s the deal. A dripping faucet isn’t just annoying. It can lead to a damp cabinet or even a hairline crack in your sink's finish if left long enough. Most people think they need a brand-new faucet the second they see a leak. Most of the time, you don't. You just need to fix the small part that gave up. I’ve seen this all over Montgomery County, from brand-new builds in Sango to older homes near Fort Campbell.

1. Worn-out rubber washers are usually the culprit

In older, two-handle faucets, a rubber washer is what actually stops the water. Every time you turn the handle, that washer gets squeezed against a metal seat. Eventually, the rubber gets hard, cracks, or just wears thin. When that happens, water finds its way through.

What I’d do first is check if you have a compression-style faucet. If you have to physically "tighten" the handle to stop the water, it’s probably a washer issue. Replacing a washer is a cheap fix, but if you don't get the exact right size, it won’t seal. I always tell folks to take the old washer to the hardware store with them. It saves you three trips.

2. A damaged or loose O-ring

If you see water seeping out around the base of the handle instead of just dripping from the spout, you’re likely looking at a bad O-ring. These are small rubber loops that keep the water inside the faucet body. Over time, they get brittle.

In a kitchen in St. Bethlehem last week, a homeowner thought their entire sink was leaking. It turned out to be a $2 O-ring that had finally snapped. We swapped it out, cleaned up the base, and the leak vanished. It’s a simple part, but it does a big job.

3. The valve seat has corroded

The valve seat is the connection between the faucet and the spout. In compression faucets, water carries minerals that can eat away at the metal seat. If the seat is pitted or rough, even a brand-new washer won't stop the leak because the surface isn't flat anymore.

Quick tip. If you replace the washer and it still drips, run your finger (carefully) over the valve seat. If it feels like sandpaper, it needs to be resurfaced or replaced. This is a common issue for Clarksville area homes with older plumbing. It takes a specific tool to smooth it out, so don't try to force it with a screwdriver.

4. Your cartridge has seen better days

Most modern single-handle faucets use a cartridge. This is a plastic or metal cylinder inside the faucet that controls the flow and temperature. They are great until they aren't. A tiny bit of grit or a hairline crack in the ceramic disc inside the cartridge is all it takes to start a drip.

Replacing a cartridge is usually straightforward, but every brand is different. You have to pull a clip, wiggle the old one out, and slide the new one in. If it’s stuck, don't yank it. You can snap the copper lines underneath if you aren't careful.

5. High water pressure is pushing through

Sometimes the faucet is fine, but your home’s water pressure is too high. If you notice the drip mostly at night or if your pipes "thump" when you turn the water off, your pressure might be set too high.

High pressure puts a lot of stress on every seal in your house. If the pressure is over 80 PSI, your faucet seals will fail much faster than they should. I usually recommend checking the pressure regulator near your main water shut-off if you’re seeing leaks at multiple faucets in your Montgomery County home.

6. Worn out springs and seats

If you have a "ball-type" faucet (usually the ones with the round, dome-shaped handle base), there are small metal springs and rubber seats inside. These work together to hold back the water.

These parts are tiny and easy to lose. If one spring gets weak, the rubber seat won't stay tight against the ball, and you’ll get a constant drip. I usually suggest just buying a full rebuild kit for these rather than trying to find one single spring.

7. Mineral buildup on the aerator

This one is sneaky. Sometimes the faucet isn't leaking from the valves; water is just getting backed up. If your aerator (the little screen at the end of the spout) is clogged with white crusty stuff, it can cause water to "weep" back out of the handle or joints.

You can usually unscrew the aerator by hand. Soak it in white vinegar for an hour, and those minerals will dissolve. It’s one of those Clarksville maintenance tasks that pays off. If the aerator is totally blocked, it can even cause a split caulk line where the faucet meets the sink because of the backpressure.

8. Loose packing nuts

Under the handle, there’s a nut that holds the stem in place. If this gets loose, water will travel up the stem and leak out from under the handle every time you turn the faucet on.

A quick turn with a wrench can often fix this. But don't go crazy. If you over-tighten it, the handle will be hard to turn and you might crack the housing. Just a snug fit is all it needs.

9. Failed seals in the spout

If your faucet has a pull-down sprayer or a swivel spout, there are seals where the spout connects to the body. If you see water pooling on the counter around the back of the sink, these seals are usually the problem.

Replacing these often involves taking the whole spout off. It’s a bit more work, but it’s better than letting water rot out your subfloor. I’ve seen many Clarksville area kitchens where a small spout leak turned into a major cabinet repair because nobody noticed the water creeping under the sink.

10. The faucet is just plain old

Sometimes, internal parts just wear out to the point where "fixing" it costs as much as a new one. If the metal body is corroded or the finish is peeling, it might be time for a faucet replacement.

New faucets are more efficient and can really update the look of your kitchen. If you're planning on listing your home soon, a fresh faucet is a small detail that Realtors in Clarksville always appreciate. It shows the house has been cared for.

What you can safely try yourself

If you’re feeling handy, you can start by shutting off the water under the sink. Turn the handles to let the pressure out. Try cleaning the aerator first, it’s the easiest win. If that doesn't work, you can try to take the handle off and look for a worn O-ring.

If you get stuck or if you see water spraying from a pipe, turn the water off at the main valve and give me a call. I’ve stepped in many times when a "five-minute fix" turned into a long afternoon.

FAQs About Kitchen Faucet Repairs

How much does a dripping faucet cost me in water bills?
A faucet that drips once per second can waste over 3,000 gallons of water a year. That’s enough for about 180 showers. It’s definitely cheaper to fix the leak than to pay the utility company for water you aren't using.

Do I have to turn off the main water to fix a faucet?
Usually, no. Most Clarksville homes have individual shut-off valves under the kitchen sink. You just turn them clockwise to stop the water to that specific faucet. If those valves are stuck or missing, then you’ll need to use the main shut-off for the whole house.

Why does my faucet only drip at night?
This is often due to water pressure. During the day, everyone is using water, so the pressure stays lower. At night, when usage stops, the pressure in the city lines can spike. If your seals are weak, that extra pressure pushes water past them.

Is it better to repair or replace a faucet?
If the faucet is less than 5–8 years old and in good physical shape, a repair is usually the way to go. If it’s an older model with a lot of mineral buildup or a damaged finish, replacing it is often a better long-term investment for your home.
