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

You’re laying in bed, trying to drift off, but there it is. That rhythmic, annoying "plink… plink… plink" coming from the kitchen. A dripping kitchen faucet isn’t just a sound that drives you crazy; it’s a waste of water and a sign that something inside your sink is giving up.

I’ve seen this a lot in homes across Clarksville, TN. Most people think they can just crank the handle tighter to make it stop. Here’s the deal: that usually just makes the problem worse by crushing the seals inside. Whether you live in Sango, St. Bethlehem, or near Fort Campbell, the hard water in Montgomery County is often the hidden culprit behind these leaks. Mineral buildup eats away at the guts of your faucet until it just can’t hold back the pressure anymore.

I remember a client over in Sango who ignored a tiny drip for months. She figured it was just a nuisance. By the time she called me, that slow drip had followed the neck of the faucet down under the sink. It sat there so long it caused a soft spot in the cabinet floor and some nasty split caulk around the sink base. We fixed the faucet, but we had to address the wood damage, too. It’s always better to catch these things early.

1. Worn Out O-Ring

The O-ring is a small rubber disc that sits on the stem to create a seal. Over time, as you turn the handle back and forth, the friction wears it down. This is usually why you see water leaking around the base of the handle every time you turn the water on.

2. A Corroded Valve Seat

The valve seat connects the faucet and the spout. If minerals from our Clarksville water build up here, the seat starts to corrode. When that happens, the seal won't fit perfectly anymore, and water will sneak through even when the handle is totally off.

3. Dirty or Damaged Aerator

Sometimes the leak isn't actually a leak, it’s just trapped water. If the aerator (the little screen at the tip) is full of grit or white crusty minerals, it holds water back. When you turn the faucet off, that trapped water slowly dribbles out for a few minutes. Cleaning it is a quick fix that saves a lot of headaches.

4. Worn Cartridge

Most modern faucets use a cartridge. It’s a plastic or brass piece inside the handle that controls the flow. If the internal seals on that cartridge get a hairline crack or just get brittle with age, the faucet will drip constantly from the spout.

5. High Water Pressure

If your faucet only drips at night or when no other water is running, your house pressure might be too high. When the pressure spikes, it can force its way past even a healthy seal. This is something I see occasionally in newer developments in Montgomery County where the pressure-reducing valve might need a tweak.

6. Old Washers

If you have an older style faucet with two handles that you have to turn several times to open, you’ve got washers. These rubber bits get flattened or hard over time. Once they lose their "squish," they can't stop the water.

7. Loose Parts

It sounds simple, but sometimes the nuts and bolts inside the handle assembly just vibrate loose over years of use. I’ve seen cases where a slightly loose packing nut was the only thing causing a steady stream to run down the back of the sink.

8. Damaged Seals

Every faucet has various seals and gaskets. If one of these gets a tiny tear, maybe from a piece of sediment passing through the line, it creates a path for water to follow. Even a microscopic nick is enough to cause a persistent drip.

9. Cracked Plastic Nuts

Underneath the sink, there are plastic nuts that hold the faucet assembly tight to the countertop. I’ve found a hairline crack in a plastic nut more than once. When that nut fails, the faucet can shift slightly, breaking the internal alignment and causing a leak that looks like it's coming from the spout.

10. Improper Installation

If the faucet was recently replaced and it’s already dripping, a seal might have been pinched during the install. It doesn't take much to ruin a new cartridge if it isn't seated perfectly in the housing.

What You Can Safely Try Yourself

If you’re feeling handy, you can usually tackle the aerator first. Just unscrew it from the tip of the spout. If it’s stuck, wrap a rag around it before using pliers so you don't scratch the finish. Soak it in white vinegar for an hour, scrub it with a toothbrush, and put it back.

You can also check the shut-off valves under the sink. If you see a damp spot or a slow drip there, try tightening the nut just a fraction of a turn. Don't go crazy, over-tightening is a recipe for a bigger flood.

When It’s Time to Call a Pro

Plumbing is one of those things where a five-minute fix can turn into a four-hour disaster if a rusted bolt snaps or a pipe cracks. If you find yourself staring at a cartridge that won't budge or if you see water damage inside your cabinets, stop what you're doing.

I tell people all the time: if you aren't comfortable shutting off the main water to your house, don't take the faucet apart. You don't want to be stuck with a geyser in your kitchen while you're hunting for the curb key.

FAQs About Dripping Faucets

Can a dripping faucet increase my water bill?
Yes. A faucet that drips just 10 times a minute can waste hundreds of gallons a year. If it's a steady stream, you’re literally pouring money down the drain.

Is it cheaper to fix a faucet or replace it?
Usually, fixing a high-quality faucet with a new $20 cartridge is better. However, if the metal body is corroded or the faucet is a cheap "builder-grade" model, I often recommend just replacing the whole unit with something that will last another ten years.

Why does my faucet leak only when I turn it on?
That’s usually a worn-out O-ring or a loose packing nut. The seal is fine when the water is off, but as soon as the internal pressure builds up, water finds the path of least resistance through the worn seal.

Does Clarksville's hard water affect my faucets?
Absolutely. The minerals in our water build up like concrete inside your fixtures. This "scale" acts like sandpaper on rubber seals, wearing them out much faster than in areas with soft water.
