10 Reasons Your Kitchen Faucet Isn’t Working (And How to Fix It)

You wake up on a Tuesday morning in your Clarksville, TN home and head straight for the coffee pot. You reach for the kitchen faucet handle to fill the carafe and you get nothing. Maybe it is just a tiny trickle. Maybe it is a loud thumping sound that feels like it is shaking the whole sink. It is a frustrating way to start the day. Kitchen faucet repair in Clarksville is one of those things people put off until the water stops flowing entirely. I have seen it happen in Sango and over in St. Bethlehem more times than I can count. Most people think they need a brand new fixture. Sometimes you do. But often it is just a small part that has given up the ghost.

What is actually happening with your faucet

When a faucet stops working, it is usually a sign that one specific component has failed. Faucets look simple on the outside but they have a lot of small parts working together. There are seals, springs, and valves that handle the constant pressure of the water in your Clarksville home. If one of those gets a hairline crack or a bit of grit in it, the whole system shuts down. I once went to a house near Fort Campbell where the homeowner was convinced a ghost was messing with his pipes because the water only trickled on certain days. It turns out he had a loose rubber washer that was acting like a swinging door inside the pipe. It was a five minute fix.

1. The shut off valves are closed

This sounds too simple to be true. You would be surprised how often a cleaning bucket or a box of trash bags slides around under the sink and bumps a valve handle. These are the two silver or plastic knobs located right against the wall under your cabinet. If they are turned even halfway, you will lose a ton of pressure.

Here is the deal. You should check these first. Make sure both the hot and cold valves are turned all the way counterclockwise. If they feel stuck, do not force them. I have seen people snap the stems off old valves and turn a small problem into a flooded kitchen in seconds. If it does not move with light finger pressure, leave it alone.

2. A clogged aerator is the main culprit

The aerator is that little screw on piece at the very tip of your faucet spout. It has a tiny screen inside that mixes air with the water to keep it from splashing. In Montgomery County, we deal with a lot of mineral buildup. Over time, those minerals create a white crust on the screen.

Quick tip. You can usually unscrew the aerator with your bare hands. If it is stuck, use a pair of pliers with a rag wrapped around the metal so you do not scratch the finish. Once it is off, look at the screen. If it looks like it is covered in salt, soak it in a cup of white vinegar for an hour. It will usually work like brand new after that.

3. The faucet cartridge has worn out

Inside the handle of your faucet is a piece called a cartridge. This is the brain of the faucet. It controls how much hot and cold water gets mixed together. These are almost always made of plastic or ceramic. Over time, the plastic can develop a hairline crack that allows water to bypass the seals.

If your handle feels "mushy" or if it is leaking from the base of the handle, the cartridge is likely shot. Every brand uses a different cartridge. A Moen cartridge won't fit a Delta faucet. You usually have to take the handle off to find the model number. It is a bit of a puzzle but it is a very common repair.

4. Worn out O-rings and seals

O-rings are tiny rubber loops that create a watertight seal between the moving parts of the faucet. If you see water pooling around the base of the faucet on top of the counter, your O-rings are probably toast. Rubber dries out and cracks over time. When that happens, water takes the path of least resistance. That path usually leads right onto your granite or laminate counters.

5. Kinked supply lines under the sink

Take a look under your sink. Most modern faucets use flexible braided steel or plastic lines to connect the faucet to the wall. If you have a lot of heavy cleaning supplies shoved under there, you might have accidentally kinked a line. It is just like a garden hose. If there is a sharp bend in the line, the water cannot get through. I have seen homeowners spend hundreds on a plumber only to find out a gallon of bleach was leaning against the hose.

6. Mineral buildup in the mixing valve

This is different from the aerator. The mixing valve is where the hot and cold lines meet. If you only get cold water but no hot water, or vice versa, sediment might be clogging one side of the valve. This happens a lot if you have recently had work done on your water heater. Bits of calcium can break loose and travel straight to your kitchen sink.

7. Frozen pipes during a Clarksville winter

If it is twenty degrees outside and your sink is on an exterior wall, your pipes might be frozen. This is a common issue in some of the older homes in Clarksville. If you turn the handle and nothing happens, check the other faucets in the house. If they work but the kitchen doesn't, you have a localized freeze.

What I would do first is open the cabinet doors. Let the warm air from the house get back there. You can even use a hairdryer on low heat to gently warm the pipes. Never use a torch or an open flame. You will end up calling the fire department instead of a handyman.

8. Blocked internal water lines

Some high end faucets have very narrow internal copper or plastic lines. If a piece of rust or a bit of solder from a recent pipe repair gets in there, it can block the flow entirely. These are hard to fix because you often cannot get to the blockage. You might have to disconnect the faucet and try to blow air through it backwards to clear the debris.

9. A damaged sprayer diverter

If you have a faucet with a pull out sprayer, there is a small part called a diverter. Its job is to stop the flow to the main spout when you trigger the sprayer. If this part gets stuck, you might get a weak flow from both or nothing at all. You can usually tell this is the problem if the sprayer works fine but the main spout does not.

10. The handle set screw is loose

Sometimes the faucet is fine but the handle is just spinning on the stem. There is a tiny screw, usually an Allen head, that holds the handle to the cartridge. If that screw backs out, you can turn the handle all day and the water will never come on. It feels like a broken faucet but it is really just a thirty second fix with a small wrench.

What you can safely try yourself

I am all for homeowners saving a buck. You can check your shut off valves and clean your aerator without any special training. Those two things fix about half of the calls I get. You can also clear out the space under your sink to make sure nothing is pinching the hoses.

If you decide to take the handle off, make sure you turn the water off at the wall first. If you don't, you are going to get a face full of water and a very wet kitchen. Also, put a rag over the drain. Those tiny screws love to jump right into the garbage disposal the second you loosen them.

When it is time to call a professional

If you have checked the easy stuff and the water still isn't flowing, it is time to call for help. Replacing a cartridge or a mixing valve can be tricky. If you use the wrong tool, you can strip the brass fittings. Once those are stripped, you are looking at a much more expensive repair.

If you see a soft spot on the floor of your cabinet or split caulk around the sink, you might have a slow leak that is damaging your home. That is not something to ignore.

Kitchen Faucet FAQs

How long should a kitchen faucet last?
Most mid-range faucets last about 15 to 20 years. If you have very hard water in Clarksville, that lifespan might be shorter due to mineral buildup. If yours is over 10 years old and starts leaking in multiple places, it is usually better to replace it than to keep repairing small parts.

Why does my faucet make a whistling sound?
That sound is usually caused by a worn out washer or a loose part inside the cartridge. The water is vibrating the loose part as it passes by. It is annoying but usually an easy fix by replacing the internal seals.

Can I use Drano to fix low water pressure?
No. Drano is for clogged drains, not for water supply lines. Never put chemicals into your water supply lines. If you have low pressure, it is a mechanical issue with the faucet or a blockage in the pipes, not something a liquid cleaner can solve.

Do I need a plumber to change a faucet?
Not necessarily. A skilled handyman can handle almost any faucet installation or repair. We are licensed and insured to handle these types of home improvements. If it involves moving major pipes behind the wall, a plumber might be needed, but for the fixture itself, we have you covered.

Why is my hot water pressure lower than the cold?
This is often a sign of sediment buildup in the hot water line or the water heater itself. Since hot water sits in a tank, minerals settle at the bottom and eventually find their way into your faucet's mixing valve.
