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

By Chris Childs

It usually starts around 2:00 AM. You’re lying in bed, the house is quiet, and then you hear it. Drip. Pause. Drip. It is one of the most annoying sounds in the world. Beyond the noise, that tiny leak is wasting gallons of water and running up your bill every single day.

If you have a kitchen faucet dripping in your Clarksville, TN home, you aren’t alone. I see this all the time across Montgomery County. Whether it is a kitchen sink in Sango or a rental property near Fort Campbell, faucets eventually give out. Most people think they need to replace the whole thing immediately, but that isn't always the case. Usually, it is just one small part that has reached the end of its life.

Here’s the deal: modern faucets are a bit like puzzles. They look simple on the outside, but inside they have O-rings, cartridges, and seals that all have to work perfectly to keep the water back.

What’s Actually Happening Inside Your Faucet?

When you turn the handle, you are moving a valve. Over time, friction and hard water take a toll on those moving parts. In Clarksville, our water can be a bit tough on plumbing. I often find a thick, white hard water crust or a worn-out rubber washer that has started to crumble inside the assembly. Once that seal is broken, gravity does the rest.

10 Common Reasons for a Dripping Kitchen Faucet

If you’re staring at that leak and wondering why it won't stop, here are the 10 most likely culprits.

  1. Worn Out O-Ring
    The O-ring is a small rubber disc that helps create a seal around the handle. If you see water leaking from the base of the handle when you turn the faucet on, this is usually the reason.
  2. Corroded Valve Seat
    The valve seat connects the faucet to the spout. Sediment can build up here and cause corrosion, which prevents the faucet from closing all the way.
  3. Worn Out Washer
    This is the classic reason for a drip. Every time you turn the water off, the washer is pressed against the valve seat. Eventually, it just wears thin or splits.
  4. Improper Washer Installation
    If you recently tried to fix the leak yourself and it got worse, the washer might be the wrong size or sitting at a slight angle. Even a hairline gap will let water through.
  5. Loose Parts
    With how often we use our kitchen sinks, the internal retaining nut can vibrate loose over time. Sometimes, just tightening things up stops the drip.
  6. Damaged Cartridge
    Most modern single-handle faucets use a cartridge. If the plastic or ceramic inside the cartridge cracks, the whole unit needs to be swapped out.
  7. Broken Seals
    Inlet and outlet seals can wear down due to constant water pressure. When these fail, you might notice water seeping out even when the faucet is off.
  8. Hard Water Buildup
    In Clarksville, mineral deposits are a huge issue. These deposits can get stuck in the aerator or the internal valves, keeping them from sealing properly.
  9. High Water Pressure
    If your faucet only drips at night when no one is using water, your home's water pressure might be too high. This forces water past perfectly good seals.
  10. Worn Out Diverter
    If you have a pull-out sprayer, the diverter is the part that switches the water between the spout and the hose. If it gets clogged or worn, it can cause a back-flow drip.

A Quick Story from the Job Site

I recently went to a house in St. Bethlehem where the homeowner tried to tackle a leaky faucet on his own. He followed a video online, but while he was taking the handle off, the tiny set screw fell out and took a bounce right down the open drain. He didn't have the drain plugged, and that $0.50 screw turned into a much bigger headache. It's a small detail, but it’s the kind of thing that happens when you're rushing.

What You Can Safely Try Yourself

If you're feeling handy, there are a couple of things you can do before you call me.

First, try cleaning the aerator. That’s the little screen at the tip of the spout. You can usually unscrew it by hand. If it’s covered in white gunk, soak it in white vinegar for an hour. It might not stop a "valve leak," but it will fix an uneven spray.

Second, check the shut-off valves under the sink. Make sure they are turned all the way on. If you see a split caulk line around the base of the faucet, that’s a sign water has been sitting there for a while. Dry it off and see if you can spot exactly where the water is coming from: the spout tip or the handle base.

When It’s Time to Call a Professional

I’m all for DIY, but some things aren't worth the stress. If you’ve replaced the washer and it’s still dripping, or if you can’t get the handle off without feeling like you’re going to snap the pipe, stop.

I’ve seen plenty of "quick fixes" turn into flooded kitchens because a pipe snapped under the sink. If you aren't comfortable working with the shut-off valves or identifying a specific cartridge model, it’s better to have someone who does this every day take a look.

Frequently Asked Questions

How long does it take to fix a leaky faucet?
Most faucet repairs take about an hour. If we have to replace the whole unit, it might take a bit longer depending on the plumbing under your sink, but I usually have you back in business pretty quickly.

Is a dripping faucet a plumbing emergency?
Not usually, but it shouldn't be ignored. A slow drip can waste over 3,000 gallons of water a year. Plus, if the leak is under the sink, it can rot your cabinets and cause mold before you even notice it.

Can I just tighten the handle to stop the leak?
If the leak is coming from the handle base, tightening the packing nut might help. But if it’s dripping from the spout, tightening the handle usually just damages the internal seals further.

Do I need to buy the parts before you arrive?
You don't have to. If we are doing a full replacement, most folks like to pick out a faucet that matches their style. If it's just a repair, I can usually source the specific cartridges or washers needed for your brand.

What brands of faucets do you repair?
I work on all the major brands like Delta, Moen, Kohler, and Pfister. If parts are available, I can fix it.
