10 Reasons Your Faucet Won’t Stop Dripping (And How to Fix It)
It is 2:00 AM in Clarksville, TN, and the house is finally quiet. Then you hear it. Drip. Drip. Drip. That rhythmic tapping coming from the kitchen or bathroom isn't just annoying; it is the sound of money leaking out of your wallet. A dripping faucet can waste hundreds of gallons of water a month, and if you live in Montgomery County, you know those utility bills add up fast. Most people think they can just crank the handle tighter to make it stop, but usually, that just makes the problem worse.
I’ve seen this a thousand times. A homeowner calls me because their sink has a steady leak that started as a tiny annoyance and turned into a puddle under the cabinet. Often, it starts with something simple like a worn washer or a bit of crusty mineral buildup from our local hard water. If you are dealing with a faucet that won't quit, here is what is actually going on behind the scenes and how we can get it fixed.
What is happening when your faucet drips?
A faucet is basically a gatekeeper for your home’s water pressure. When you turn the handle, you are opening a valve to let water through. When you close it, you are creating a seal that has to hold back a lot of force. If any part of that seal is compromised, water finds a way out.
I remember a client over in Sango who had a tiny drip in her guest bathroom. She ignored it for three months because "it wasn't that bad." By the time she called Fix It Quick Handyman Service LLC, the constant moisture had caused a soft spot in the floor joist and some nasty split caulk around the base of the sink. A ten-minute fix turned into a much bigger job because that little drip never takes a day off.
1. The classic worn-out washer
This is the number one reason faucets leak. Inside your faucet, there is a little rubber or silicone washer that gets pressed down to stop the water flow. Over time, the friction and the pressure wear that rubber down. It might get a hairline crack or just get thin and brittle. When that happens, the seal isn't tight anymore, and the water starts sneaking past.
If you have an older compression-style faucet (the kind with two handles), this is almost always the culprit. Replacing a washer is a cheap fix, but you have to make sure you get the exact right size. A washer that is even a tiny bit too small will still let water through.
2. A damaged or worn O-ring
If you notice water leaking specifically from the base of the handle when you turn the water on, the O-ring is likely to blame. This is a small rubber ring that sits on the valve stem to keep water from coming up the handle. In my experience, these wear out faster if you have a lot of sediment in your water.

3. Corrosion in the valve seat
The valve seat is the part of the faucet that the washer actually presses against. Think of it like a door frame. If the frame is warped or rotted, the door won't shut right no matter how good the lock is. In Clarksville, our water can be a bit hard on plumbing. Minerals build up on the valve seat and cause it to corrode. Once that surface is no longer smooth, the washer can't make a watertight seal. I can sometimes grind these smooth again, but often it is better to just replace the seat or the whole unit.
4. Cartridge failure
Most modern faucets use a cartridge instead of a bunch of separate washers and screws. It is a self-contained unit that handles the mixing of hot and cold water. If the internal seals of the cartridge fail, the whole thing needs to be swapped out. You'll know it's a cartridge issue if the handle feels "mushy" or if it is getting harder to turn.
5. Worn-out seals and springs
In "ball-type" faucets, the ones with the single lever handle, there are small springs and rubber seals that hold everything in place. These parts are constantly moving. Over time, the springs lose their tension or the seals get flattened. It is usually best to buy a "rebuild kit" and replace all these small parts at once rather than trying to figure out which specific one is the problem.
6. High water pressure issues
Sometimes the faucet is fine, but your home’s water pressure is too high. If you notice that your faucet only drips at night when no one is using water, or if multiple faucets in your Clarksville home start dripping at the same time, this might be the reason. High pressure forces water past seals that would otherwise be perfectly fine. This is a bigger issue that usually requires checking your pressure-reducing valve (PRV).
7. Loose parts from daily use
We use our sinks dozens of times a day. All that twisting and pulling can vibrate internal screws loose. I’ve gone into jobs where the "leak" was actually just a packing nut that had backed off a quarter turn. Tightening things up is the easiest fix there is, but you have to be careful not to over-tighten and crack the housing.
8. Hard water mineral buildup
Clarksville residents deal with mineral deposits quite a bit. These minerals act like sandpaper inside your faucet. They scratch up the smooth surfaces of the valves and prevent them from closing all the way. You might see white, crusty stuff around the aerator or the base of the faucet. If it's inside the valve, it's doing damage every time you turn the handle.
9. Deteriorated packing nuts
The packing nut is what holds the stem of the faucet in place. Inside that nut is "packing" material that keeps water from leaking out around the stem. If this nut gets loose or the packing material dries out and crumbles, you'll see water pooling on top of the sink every time you wash your hands.
10. Hot water line stress
Heat makes things expand. The rubber components on your hot water side take a much bigger beating than the ones on the cold side. If you notice that only the hot handle is dripping, it is likely that the heat has finally cooked the seals. Keeping your water heater at a reasonable temperature can actually help your faucets last longer.
What you can safely try yourself
If you are handy and want to take a crack at it, here is what I’d do first. First, turn off the water supply under the sink. You don't want a geyser in your kitchen. Open the faucet to drain the remaining water. You can try taking the handle off to see if there is any obvious debris or a loose screw.
Quick tip: Put a rag over the drain hole before you start taking things apart. There is nothing worse than watching a tiny, irreplaceable screw bounce once and disappear down the pipe. If you see a lot of white buildup, you can try soaking the parts in white vinegar to dissolve the minerals.
When it is time to call a pro
If you’ve replaced the washer and it’s still dripping, or if you see water spraying from a weird spot, it is time to stop. I've seen homeowners try to force a stuck cartridge out and end up breaking the entire copper manifold behind the wall. That turns a simple repair into a massive plumbing bill.
If your faucet is old or if you see a hairline crack in the metal body, it is usually cheaper and better to just replace the whole thing. I can help you pick out a reliable model that will actually last in our Montgomery County climate.

FAQs About Dripping Faucets
How much water does a dripping faucet actually waste?
A faucet that drips once per second can waste over 3,000 gallons of water a year. That is enough for about 180 showers. In Clarksville, that can easily add $20 to $50 to your annual water bill for a single leak.
Can I just use WD-40 to stop a squeaky or leaky handle?
No. WD-40 is not a lubricant for plumbing seals. It can actually degrade rubber washers and O-rings over time. If things are sticking, you need specialized plumber's grease, which is waterproof and safe for your drinking water.
Why does my faucet drip more at night?
Water usage in Clarksville drops significantly at night when people are sleeping. This causes the pressure in the city lines to rise. If you have a weak seal or a failing pressure regulator, that extra nighttime pressure will force a drip that you might not see during the day.
Is it better to repair an old faucet or just buy a new one?
If the faucet is more than 10-15 years old and has significant mineral buildup, I usually recommend replacement. The cost of labor and multiple repair parts often gets close to the price of a brand-new, more efficient model that will give you another decade of service.
