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

It is 2 AM. You are trying to sleep in your home in Clarksville, TN, but you hear it. The rhythmic sound of water hitting the sink basin. Drip. Drip. Drip. It is not just annoying. It is literally money going down the drain. Whether you are in St. Bethlehem or over in Sango, a leaky faucet is one of those common plumbing maintenance issues that seems small until your water bill arrives. Most folks ignore it for a few weeks. Then they notice the green mineral buildup or a tiny hairline crack in the handle and realize they should have called a professional sooner. I have spent years helping homeowners in Montgomery County handle these exact headaches.

If you are dealing with a faucet dripping in Clarksville, TN, I want to help you understand why it is happening and what you can do about it. Here is the deal. Most faucet leaks come down to a few cheap parts that have simply reached the end of their life.

Why that small drip is a big deal

You might think a tiny drip does not matter much. I once had a client in Sango who thought the same thing about a guest bathroom sink. They left it dripping for three months because they rarely used that room. By the time they called me, the constant moisture had caused a soft spot in the vanity cabinet and some split caulk around the backsplash. That simple ten dollar fix turned into a much larger repair job.

Beyond the damage to your cabinets, a dripping faucet can waste hundreds of gallons of water a year. In Clarksville, our water can be a bit hard, which means those drips leave behind nasty white scales that are tough to scrub off. It is better to handle it now before the mineral buildup ruins the finish on your expensive fixtures.

1. Worn out washers are the usual suspects

In older compression faucets, a rubber washer is what actually stops the water. Every time you turn the handle off, you are squishing that rubber against a metal seat to create a seal. Over time, that friction wears the rubber down. It gets flattened or brittle. When that happens, the seal is not tight anymore. Water finds the path of least resistance and starts leaking out. Replacing a washer is one of the most common leaky faucet repair tasks I handle.

2. Damaged or dirty O-rings

If you notice water leaking around the base of the faucet handle rather than just the spout, the O-ring is likely the problem. This is a small rubber ring that sits on the valve stem to keep water from pushing upward toward the handle. In my experience, these wear out quickly if the faucet is used frequently. A quick tip is to check the O-ring whenever you have the faucet apart for any other reason. It is a cheap part to replace while you are already in there.

3. A corroded valve seat

The valve seat is the connection between the faucet and the spout. In compression faucets, the washer presses against this seat. If you have hard water in Clarksville, minerals can build up on this seat and cause it to corrode. Even if you put in a brand new washer, a corroded valve seat will still allow water to seep through because the surface is not smooth. You can sometimes clean these with vinegar, but if the corrosion is deep, the seat needs to be replaced or resurfaced.

4. Problems with the faucet cartridge

Many modern faucets do not use washers. They use a cartridge. This is a plastic or metal piece inside the handle that regulates the flow. If the cartridge gets a crack or the internal seals fail, the faucet will drip. Cartridges are specific to the brand and model of your faucet. What I'd do first is find the model number of your sink before heading to the hardware store because there are hundreds of different versions that all look similar.

5. High water pressure issues

Sometimes the faucet is fine, but your home's water pressure is just too high. If you notice several faucets dripping at once or if the drip only happens at certain times of the day, this might be the culprit. High pressure puts a lot of stress on your valves and seals. I often recommend installing a water pressure regulator if I see signs that the plumbing is being pushed too hard. It protects your faucets, your dishwasher, and your water heater.

6. Loose internal parts

Think about how many times a day you turn your kitchen faucet on and off. All that movement can cause internal screws and nuts to vibrate loose. If the packing nut or the stem screw gets loose, the seal becomes inconsistent. Sometimes just taking the handle off and tightening the internal components is enough to stop a minor leak. It does not always require new parts.

7. Mineral buildup from Clarksville hard water

We have plenty of minerals in our water here in Montgomery County. These minerals love to settle inside your faucet. They can get stuck in the aerator or inside the valve itself. When sediment gets trapped between a seal and the valve, it creates a gap. That gap is all water needs to start a drip. Regular plumbing maintenance like soaking your aerator in vinegar can prevent some of these issues from starting.

8. Worn out seals in disc faucets

Disc faucets use two ceramic discs to control water flow. These are usually very reliable, but the rubber seals at the bottom of the discs can fail. If these seals get pinched or worn, water will bypass the discs and leak out of the spout. Ceramic discs are tough, but they can still be damaged if a piece of grit or metal gets stuck between them.

9. Issues with the hot water line

I have seen cases where only the hot water side of a faucet drips. This can happen if your water heater is set too high or if there is a problem with the thermal expansion in your pipes. The heat can cause rubber washers and O-rings to degrade much faster than they would on the cold side. If you are constantly replacing the hot water washer, it might be time to look at your water heater settings.

10. A broken or loose packing nut

The packing nut is what holds the stem of the faucet in place. If this nut is cracked or just loose, you will see water bubbling up from under the handle. I have seen homeowners try to over-tighten these, which usually just cracks the nut and makes the leak worse. A gentle snugging is usually all it takes if the part is still in good shape.

What you can safely try yourself

If you are feeling handy, there are a few things you can try before calling me. First, always turn off the water supply valves under the sink. You do not want a geyser in your kitchen. You can try unscrewing the aerator at the tip of the spout and cleaning out any grit. Sometimes that is the only issue. You can also try tightening the handle screws if they feel wobbly. If the leak persists after basic tightening, it is usually time to look deeper.

When it is time to call a professional

I tell my neighbors in Clarksville that if you are worried about stripping a screw or if you cannot get the water to shut off completely, give me a call. I have the right tools to remove stubborn, corroded parts without damaging your expensive sink. If you see water pooling inside your cabinet or notice a soft spot in the wood, that is an emergency. You do not want mold growing under there. It is much cheaper to fix a leak than it is to replace a subfloor.

Common Questions About Faucet Repairs

How much water does a dripping faucet actually waste?
A faucet that drips once per second can waste over 3,000 gallons of water in a year. That is enough to take more than 180 showers. It adds up on your monthly bill faster than you might think.

Do I need to replace the whole faucet if it is dripping?
Usually, you do not. Most leaks are caused by small internal parts like washers or cartridges that cost a fraction of a new faucet. I only recommend a full replacement if the faucet body itself is corroded or if you just want a new look.

Why does my faucet drip more at night?
Water pressure in city lines often increases at night when fewer people are using water. If your faucet has a weak seal, that extra pressure can force water through, making the drip more noticeable while you are trying to sleep.

Can I use any washer to fix my leak?
No. Washers come in many different thicknesses and diameters. Using the wrong size might stop the leak for a day, but it will quickly fail or even damage the valve seat. It is best to take the old part with you to the store to match it exactly.
