Why Is My Kitchen Faucet Making A Humming Noise?

A kitchen faucet is a type of water faucet typically installed in the kitchen sink. It fills pots and pans with water, washes dishes and food, prepares raw meats for cooking, and rinses fruits and vegetables.

Your kitchen faucet is making a humming noise because of a leaking piping system, a loose handle that is letting water escape around the edges of the cartridge, causing an annoying sound. To fix this, check your entire piping system to prevent more leaks and tighten the nut at the base of your faucet.

If none of these conditions apply to you, then there’s a higher chance that the humming noise results from something else, like a loose handle or a worn-out washer.

To fix a humming faucet, you must first determine the cause of the leak. After doing this, you can proceed to fix the problem. Here’s how to do it:

  1. Tighten the Nut

First, tighten the nut at the base of your faucet. Don’t over-tighten it; snug it up until it’s tight enough to stop water from leaking. Then, use a wrench to tighten it again, this time to the proper amount.

  1. Install A New Faucet Cartridge

Perform this step only if you don’t already have a new cartridge installed. Use pliers to remove the old cartridge and install a new one – This will prevent water from coming out from around the edges of your faucet valve.

  1. Replace the Sparking

To stop the humming noise:

  • Replace your old washer with a new one.
  • If you can’t get the old washer out – or it’s rusted, use a hammer to remove the faucet handle. Use a screwdriver for this part.
  • Remove the nut and pull it out, releasing the cartridge.
  • Remove the water from your faucet, remove the cartridge and replace it with a new one.
  1. Replace the Faucet Handle

Finally, replace the faucet handle to stop the noise. Use pliers to remove the old handle, then use a screwdriver to remove and nut. This will release the faucet from the wall.

You can replace the faucet handle with a new one if you have one that’s better quality; otherwise, stick with the original design.

  1. Buy A New Valve

If replacing the handle doesn’t work, you’ll need to replace the whole faucet. These are available at home improvement and department stores.

Once you install your replacement, ensure the leak has completely stopped before using it again. If it leaks again, you should look at ordering a new faucet.

  1. Repair All Leaks

Check your entire piping system to prevent more leaks. If you think it’s leaking because of a bent hose, then you should contact an expert to repair this – but first, let it dry out for a few days.

If your pipes are loose or not installed correctly, this can also cause leaks. You can get this fixed by contacting a plumber.

  1. Check the Pipes

Check the pipes behind your faucet for signs of leaks. If you find that there are leaks, then you should repair them. You can do this yourself or call a plumber if you think that the leak is significant enough not to fix it easily.

  1. Repair the Leaks

If you have many leaks, fix them immediately. You can do this by repairing the leaking pipes and condense – meaning that you can remove the pipes from the wall and drier them out.

You will have to remove your faucet, but this should not be difficult – it may take several people. Depending on the major repair, paying a plumber could be cheaper than doing all these repairs yourself.

  1. Drip Repair

If you’re not at a point where you’re comfortable taking on the repairs yourself, then you can choose to hire a professional to replace the pipes and fix the leaks.

Someone who knows what they are doing should be the one to do this- so if you don’t know anyone, then this will probably not be for you.

Just remember: You should never attempt to repair your plumbing system. A professional should take care of it. If you don’t, you might have more problems than when you started.

7 Reasons why Kitchen Faucets Makes a Humming Noise (How to Fix)

Worn Out or Loose Faucet WashersAs water passes through the faucet on a kitchen sink, it rests momentarily in the space between the washer and spout.

If the washers get worn out or loose in their seats, it will cause a humming noise. Solution: Replace washers with replacement parts designed to fix this issue.

Worn Out or Loose Faucet Mounting HardwareIf the washers or mounting hardware on the faucet get worn out and loose, it will cause a humming noise.
Solution: Tighten the hardware with replacement parts.
Clogged Water Systems or ToiletsIf your kitchen sink water system clogs up frequently or your toilet runs continuously, you can hear a hum in your faucets caused by low water pressure.

Solution: Check the master water valve in your house and see if it needs replacement.

Low Water PressureWater pressure gets measured in GPM; therefore, the humming noise will be audible if your faucet produces less than twenty-five inches of water pressure.

Solution: Get a new main water line.

High Water PressureIf your kitchen faucet produces more than sixty-five inches of water pressure, it can cause a humming noise in the faucet.

Solution: Get a new main water line. This should solve the matter. You might need to have an additional water pressure regulator installed on your main water line.

Stuck Or Broken Centerset FaucetsCenterset faucets often have a humming noise and a stuck or broken center drive. The fix: replace the center drive.
Damaged Water FilterA damaged water filter can cause a humming noise that you can hear in the faucet in your kitchen sink. The fix: Replace or repair the damaged filter.

Should Faucets Be Open When Turning the Water Back On?

Yes! You should open all faucets before turning on the main water in the house. This allows any trapped air to get purged from the system and eliminates any ‘banging’ in the pipes.

This also is a way to flush out any dirt in the system since its last use. Leaving the faucets open while the main water supply is on will allow any gas in the pipes to escape.

Turning off the water and re-opening it also helps to clear away any sediment that has built up in your pipes. This is especially important if you have well-watered or other non-municipal water supplies.

Finally, Turning on the water before all your faucets, tubs and showers are open means you risk getting a strange rush of air in the pipes.

Why Is My Kitchen Faucet Making A Humming Noise?

This can damage your appliances, especially if you have a gas stove. Leaving the faucet open while the water is on will eliminate this risk.

This will also help to prevent any damage from the water pressure in your pipes. You want to allow your pipes to fill up with water at a gentle pace so no cracks or breaks occur.

So, when you turn on the water this weekend, remember the reasons above and open all the faucets ahead of time. Your home will be safe and secure, and you’ll know that all the air has been purged from your system.

Why Is My Sink Making a High-Pitched Noise When Off?

High water pressure at home is a common problem that leads to a high-pitched leaky noise from your sink. The problem usually occurs when the water pressure is too low in the lines at the house and between your faucets, so water can’t flow through them.

The air builds up until it’s forced out of the faucet by pumping water. This can happen in the faucet lines and the drain pipe directly below them.

This is most likely a problem at the main water shutoff valve on your home’s distribution system, probably in your garage.

If you have a well, this is usually where the main water shutoff valve is.

In older homes with two- or three-bedroom homes with a central kitchen, there often was a separate sink in the kitchen and usually not connected to any pipes or fixtures like a bathtub or shower.

You can remove the sock or debris from the drain to see if there’s a restrictor. This is a small piece of metal or plastic (like a pebble) that restricts the drain and causes a water hammer.

If there is a restrictor, you must remove it for proper drainage. Usually, you find one of these devices on bathroom sinks, but rarely in the kitchen sinks.

The devices typically look like a round-ended tube in the center of the drain with water flowing around it; if you see anything that could restrict the flow, remove it.

How Does Air Get Trapped in Water Pipes?

Air gets trapped in water pipes when the pressure on one end of the pipe is lower than the pressure on the other. For example, if water runs out slower than pumping, air can become trapped in stagnant pockets of water.

We call this process cavitation, which can cause significant problems with pipelines after you install them.

The most common place for air trapped in water pipes is the transition between a wall-mounted stop valve and a horizontal pipe.

Why Is My Kitchen Faucet Making A Humming Noise?

I normally use wall-mounted stop valves for sinks, laundry machines, utility sinks, and other floor-mounted utilities. They generally have one straight 90-degree arm and one angled arm.

The angled arm is the filling port, and the straight arm is for shutoff. When you turn on the water at these valves, the pressure in the pipe builds up rapidly, causing a void in the water column behind the valve, which often collapses.

This collapse causes a series of tiny bubbles (cavitation) to form rapidly, collapsing into air pockets.

You can solve this by simply modifying the stop valve, a compression stop valve. This is an easy modification that will virtually eliminate air trapping issues.

Take a nylon washer about half the thickness of the existing washer and slide it behind the valve stem. This is best done when you perform maintenance on the valve or pipe, so you unscrew the existing brass washer and replace it with the nylon one.

Why Does My Plumbing Sound Like a Foghorn?

A foghorn sound in your plumbing could be several things.

Faulty Ballcock – This could result from the ballcock mechanism not working properly, which is often due to mineral buildup from hard water deposits or from a buildup of lime and other deposits over time.

The plunger has to work harder to push the water out so that you can use your water again for flushing purposes. Hearing a foghorn-type sound usually requires the flushing cycle to finish and start up again.

Mineral Buildup in The Pipes – Hard water deposits can also cause mineral buildup from softened water from the prolonged operation of your faucet without flushing.

If you are not flushing regularly, this can cause mineral/hard water deposits to build up in your pipes and cause the sound of a foghorn. It can also result from a combination of the downside of #1 and #3.

Toilet, Sink, Or Tub Overflow – A foghorn sound could also result from your toilet, sink, or tub overflow. If it’s overflowing, the toilet flapper is not closing properly, allowing the water to spill into your bowl.

The same applies to sinks and tubs as well. The flapper can become worn or damaged, causing it not to close properly. If this is the case, you will hear a foghorn-like sound when you flush your toilet or turn on the tap in your sink or tub.

Flush the toilet or turn on the water in your sink or tub to see if it’s overflowing, and fixing that issue will usually fix this problem.

Your Toilet, Sink, Or Tub Is Empty – If your toilet is empty and you have a foghorn-type sound in your plumbing, you probably did not run the flushing cycle after you finished your business.

You will only hear this if you turn off the water in your bowl or sink before it reaches the end of its flushing cycle.

Your Toilet, Sink, Or Tub Is Full- The same thing with #4 applies when the handle on your toilet tank is up, and the water levels in the bowl is high.

If you have a foghorn-like sound in your plumbing when your toilet tank is full, you probably did not run the flushing cycle after you finished up your business.

You will only hear this if you turn off the water in your bowl or sink before it reaches the end of its flushing cycle.

Why Is My Sink Faucet Squealing? (4 Reasons and Solutions)

Binding Metal ThreadWater pressure can bind the metal thread onto the faucet and cause a squealing sound.  

-Lubricate the threads with Vaseline or WD-40 to free up any binding.

-Adjust the water pressure to less than 40 PSI.

-Keep a safer distance from running water and air vents when cleaning handrails or ventilation grates under sinks.

A Bad-Fitting StrainerThe strainer may rub against its base and cause a squealing sound.

  -Use a strainer with larger openings or a new one.

-Adjust the water pressure to less than 40 PSI.

-Clean the faucet’s threads with WD40 or Vaseline to remove any dirt and debris which may make them too tight for the faucet. Note: If this problem persists, have your parts replaced.
A Bad Faucet AssemblyThis could result from a loose or damaged washer, which allows too much water into the faucet assembly.

-Fix the problem by replacing the faucet with a new one. You may consider buying a new washer with a spring mechanism to lessen the risk of breaking by tightening them too much.

-Check your other faucets for leaks and problems. If this problem persists, replace your faucet.

NOTE: If you have never replaced a faucet, take it to a professional water faucet repair shop. 4. Loose mounting screws

These can loosen while tightening and cause the unit to fall off its mounting bracket.

-Replace the screws with new ones of the same size. Ensure the washer is tight for each hole before tightening the two screw points.

-Take the old faucet off the hole and tighten the new screws. Use a screwdriver to make sure you put in all the fasteners.

-Use anti-seize on all mounting screws before putting them back on your faucet, so they don’t come off while tightening down.

A Bad Faucet WasherThese can become loose or damaged, which can cause water to leak into the sink trap, where it never drains out.


-Replace the washer if it’s loose or damaged. Regular cleaning with a brass wire brush will help keep these in good condition.

-A washer will also come off occasionally, especially if the sink is not draining properly.

In cases like this, it’s better to replace the whole faucet assembly than to go through the back and forth of trying to fix it.

Water damage can occur while you are trying to fix the faucet.

-Check your other faucets for leaks and problems. If this problem persists, replace your faucet.

How Much Does It Cost to Fix Water Hammer

Checking on the water hammer problem would be a good idea, especially if the problem is located in a small area.

To check your water hammer, get out your measuring tape and measure the distance between where the water enters and leaves your plumbing line.

Take note of this measurement and what you think it should be. Then test an area near this valve for any trouble spots.

If there is a problem, you should go back to the location where water enters or leaves the pipe and place a device that lets air through. This will reduce the knock.

You can buy these devices at most hardware stores or make one yourself. Air chambers and air gaps are perfect for this job if you can access them on your plumbing lines.

1.     Steam-Flow-Driven water hammer·       Usually around $78 but always less than $300
2.     Condensate-Induced water hammer·       Usually around $78 but always less than $300

What Are the Three Valves Under the Kitchen Sink? And Their Functions.

Hot Water supply valveThe main purpose of this valve is to provide you with hot water whenever you need it. The hot water supply valve allows cold water drainage from the faucet into the drain.  

When water travels through a pipe, it gets warmed up, and to prevent further heating and corrosion of your pipes, it’s necessary to have a heater at the destination point.

This heater warms up the incoming cold water and produces hot water as required in our daily life.
Cold Water supply valveThe cold-water supply valve has the same function as the hot water supply valve, except that it provides you with cold potable (drinkable) water instead of connecting to a heater.


You need this when you want to get a glass of ice-cold water or when hot tap water diverts to another destination, such as a sink or bathtub, via another source.

The cold-water supply valve also allows the drainage of cold water into the drain.

Drain ValveThe purpose of the drain valve is to allow you to divert soaking water into your city garbage disposal or sink.


Whichever way you choose, your plumber must be able to come up with a way to provide you with hot or cold water.

A good plumber would know how to solve this problem to meet your needs and expectations.

Are All Faucet Supply Lines the Same?

No! There are several different kinds of faucet supply lines. Some of the features you may see on these supply lines include the following:

The ceramic disc valve is the most popular style of the faucet supply line. The ceramic disc valve supply lines comprise ceramic and metal.

The ceramic disc valve supply lines offer great durability and reliability over the metal stem fitting and the plastic push-fit connection.

Why Is My Kitchen Faucet Making A Humming Noise?

These faucet supply lines are ideal for high-pressure applications, as they have a higher resistance to leaks than the metal stem fitting or plastic push-fit connection.

The metal stem fitting, often called the “mushroom” fitting, connects directly to the faucet body. The opening on these supply lines is larger than the ceramic disc valve line.

Using these lines on high-pressure applications or in areas where common freezing temperatures are not suitable.

They are also common as an alternative when you need a repair or replacement on existing faucets.

Plastic push-fit connection faucet supply lines comprise ABS Plastic. I often use these lines as an alternative to the metal stem fitting or ceramic disc valve line when you need a repair or replacement on existing faucets.

These lines are not for high-pressure applications and do not have the same resistance to leaks as the metal stem fitting or ceramic disc valve supply line.

You can also use plastic push-fit connection faucet supply lines when installing new faucets in areas where freezing temperatures are common.

These supply lines are also called Flexible Supply Lines or Metal Braided Hoses.

You should not confuse the ceramic disc valve or metal stem fitting faucet supply lines with the flexible supply lines, which you’ll find sold under other names such as Flexible Water Lines, Metal Braided Hoses, or Plastic Push Fit Connection Supply Lines.

The flexible supply lines differ from the “Metal Braided Hoses” or “Metal Push Fit Connection Supply Lines.”

These flexible supply lines do not have the same resistance to leaks; you should not use them on high-pressure applications or in freezing temperatures. It’s also best to avoid these flexible supply lines when you are replacing existing faucets.


Faucets boast essential parts of the cooking process. Deciding on what style of faucet to use is a matter of personal preference, but finding a good quality one is vital.

Many companies manufacture kitchen faucets today, but purchasing one from a reputable company is best.
