Why Do Faucets Squeal When Turned On? 3 Home Remedies

Why Does My Faucet Squeal When I Turn It On?

Is your faucet making an annoying squeal every time you turn it on? You’re not alone! Many people experience this issue, and it can be quite a nuisance.

The sound you’re hearing, often described as a high-pitched squeal or whistling, is typically caused by an issue within the faucet or the pipes supplying it.

While it may seem like a minor annoyance, it could potentially indicate a more significant problem.

There are several common causes, ranging from a loose component in the faucet to a water pressure issue.

This article will explore these causes in detail and provide some simple fixes you can try at home.

1. Water Pressure Problems

High water pressure

I was clueless the first time I noticed a squeal from my faucet. After researching, I discovered that extraordinarily high water pressure could be the culprit.

High water pressure, while great for a refreshing shower, can damage your plumbing system.

High water pressure forces your faucet and pipes to work harder than necessary. The intense pressure can cause the water to rush through your pipes too quickly, generating the unpleasant squeal you hear.

How to measure water pressure

I found out that measuring water pressure can be a DIY task. All you need is a pressure gauge that can easily be screwed onto a hose bib or washing machine bib.

If the reading is above 80 psi (pound per square inch), that’s a sign of high water pressure.

Low water pressure

On the flip side, low water pressure can also cause your faucet to make that annoying squealing sound.

I’ve noticed this, especially when using the faucet simultaneously with another water-consuming appliance like the washing machine or dishwasher.

Consequences of low pressure

Low pressure affects your faucet’s performance and can cause a pipe vibration that results in a squealing or whistling sound.

Solutions and fixes

There are a few ways to fix this. You could adjust the pressure-reducing valve if your system has one or consult a professional plumber for the best solution.

Remember, even a simple task can have complexities, so it’s always best to seek professional advice when unsure.

2. Sediment Buildup

One of the more surprising discoveries I made during my quest to quell my squealing faucet was the role of sediment buildup.

Sediment Accumulation

Sediment buildup is the collection of minerals such as calcium and magnesium that get deposited over time.

These minerals are naturally present in water. When I first moved into my home, I didn’t think much about the water quality or its potential impact on my pipes.

However, I soon learned that hard water with high mineral content can accumulate sediment in the pipes and faucet, causing many problems.

How It Affects Faucet Operation

The accumulation of sediment can severely affect the operation of your faucet. One day, I woke up to find that my faucet was trickling water instead of its usual steady flow.

I was initially puzzled, but when I took the faucet apart, I found a grimy buildup of hardened minerals. These deposits blocked the water flow, causing it to squeal as it squeezed through the small openings.

DIY Cleaning Methods

The good news is that you can often resolve sediment buildup with simple DIY cleaning methods. I found that white vinegar, a common household item, works wonders.

I disassembled my faucet and soaked the affected parts in vinegar overnight. The acid in the vinegar dissolved the mineral deposits, and after a thorough rinse and reassembly, my faucet was back to running smoothly – and quietly!

Remember, always handle plumbing parts carefully during disassembly and reassembly. It’s okay to ask for help or hire a professional if you’re unsure.

3. Faulty Faucet Washer

When I thought I had addressed all my faucet woes, another hurdle came – a faulty faucet washer.

The washer in a faucet is a small, typically rubber or silicone disc that acts as a sealant.

Washer’s Role in Faucet Operation

In my experience, I’ve realized that the washer plays a surprisingly significant role in the smooth operation of a faucet.

It’s designed to seal the waterway when the faucet is turned off, preventing water from dripping from the tap.

When you turn the faucet on, the washer moves away, opening the waterway and allowing the water to flow freely.

Signs of a Faulty Washer

One of the telltale signs of a faulty washer is a faucet that constantly drips, even when it’s purportedly turned off.

I faced this exact situation: the slow, continuous drip, drip, drip that became an annoying background rhythm in my kitchen.

It was not just the noise; this also pointed to a waste of water, which I wanted to fix immediately.

Replacing the Washer

Replacing the washer became my next project. I armed myself with a new washer (of the correct size!) and my trusty toolkit.

Remember, ensure the water supply is turned off before you do anything. Then, I carefully disassembled the faucet, following an online tutorial, and replaced the worn-out washer.

Once everything was reassembled, I hesitantly turned the water back on. To my relief, the drip had stopped!

And that’s how I learned that sometimes, the small things – like a worn-out washer – can cause the biggest headaches.

4. Air in Water Line

When I thought I was a faucet-fixing pro, I stumbled on a new issue: Air in the water line. This can happen when the water supply is interrupted, causing air to seep into the pipes.

A common cause might be plumbing work or an empty city water tower.

How Air Gets into the Water Line

I first realized there was air in my water line when my faucets started to sputter and spit. It was like they were choking on something, and then it hit me – air.

Air can enter the water line in various ways: through a break in the pipe, during repairs or installation, or even when the water supply is temporarily turned off.

Effects Of Air On Faucet Noises

The effects of air in the water line were immediately noticeable. Whenever I turned on the faucet, it would make a series of loud, annoying gurgling noises.

I could hear the air being forced out with the water. It was not only startling but also embarrassing when guests were over.

Bleeding the Air from the Lines

Thankfully, bleeding the air from the lines is not a Herculean task. I started by opening all the faucets in my house and then turned on the main water supply.

As the water filled the pipes, it forced the air out. I let the water run until it flowed smoothly without sputtering, signaling that all the air had been expelled.

This simple procedure saved me from the embarrassing gurgling noises and brought back the peace in my house.

And there you have it, my journey with air in the water line. It’s these little adventures that keep my relationship with plumbing interesting!

5. Loose Parts

Identifying Loose Components

My adventures in plumbing took an exciting turn when I discovered loose parts contributing to the faucet noises.

One day, I noticed an odd rattling sound whenever I turned on the water. Upon investigation, I realized that specific components within the faucet assembly had become loose over time.

It felt like a detective story, where each little clue was leading me to the source of the mysterious sound.

The Impact on Faucet Noise

The impact of these loose parts on the faucet noise was surprisingly significant. Every time I turned on the tap, it was like someone was shaking a box of rocks.

The loose components would rattle and vibrate, causing a noticeable noise that was quite jarring. Even my cat noticed, as she always perked up her ears whenever I turned on the faucet.

Tightening and Securing Loose Parts

Armed with a wrench and a newfound determination, I tightened the loose parts. It was a delicate task, requiring a careful hand and an eye for detail.

I could feel the parts coming together, each turn of the wrench bringing a sense of satisfaction. Once all the components were secured, I turned on the faucet, holding my breath in anticipation.

To my delight, the faucet ran smoothly with barely a whisper, the rattling noise vanishing as if it had never been there. It was a small victory, but a victory nonetheless in my ongoing relationship with plumbing.

6. Water Hammer

Ah, my first encounter with the water hammer phenomenon! This was undoubtedly a game-changer for me in my journey with plumbing.

For those not in the know, a water hammer is a shock wave that travels through the pipes, typically created by a sudden stop in water flow.

Imagine a train abruptly halting on its tracks, with all the energy having nowhere to go but to jolt through the train itself—that’s precisely what happens in the pipes.

This was an entirely new concept, and learning about it felt like I had unlocked a secret level in my plumbing adventures.

Its Impact on Faucet Noises

When it comes to faucet noises, the impact of a water hammer can be pretty startling. I remember the first time I heard it.

I was enjoying a quiet evening when suddenly, I heard this loud thud coming from my faucet. At first, I thought maybe it was just a one-time thing.

But then it started happening frequently. Every time I’d quickly shut off the water, there was this resounding noise that echoed through the house. It was like my pipes were complaining about my abrupt actions!

Methods to Reduce or Eliminate Water Hammer

As you can imagine, this constant clanging wasn’t music to my ears. So, I decided to dive in and figure out how to reduce or eliminate this water hammer.

It turns out that installing a water hammer arrestor—a device that absorbs the shock wave—can help resolve this issue.

So, equipped with my trusty tools and a newfound determination, I installed one myself. It was challenging, but the sound of a quiet, peaceful faucet afterward was well worth the effort.

Now, whenever I shut off the water, it’s just…silence. Ah, the sweet sound of plumbing success!

7. Worn Out Cartridge or Valve

You might not know this, but behind every reliable faucet, there’s a hardworking cartridge or valve. These small, often overlooked components are the unsung heroes of our plumbing system.

They control water flow and temperature by opening or closing in response to the movement of the faucet handle. I like to think of them as the gatekeepers, holding back the flood and letting it loose when needed.

Signs of Wear and Tear

Over time, as with many things, these cartridges or valves can wear out. How did I know? Well, my faucet started acting up – dripping, no matter how hard I turned the handle.

Then, there was a sudden change in water pressure, and it took forever to get hot water. It was like hosting a guest who overstays their welcome – quite inconvenient and frustrating.

Replacing the Cartridge or Valve

Replacing a worn-out cartridge or valve might seem daunting, but trust me, it’s doable! I remember the first time I did it.

After watching many YouTube tutorials and making a quick trip to the hardware store, I rolled up my sleeves and got to work.

It took some fiddling, a few choice words, and a lot of patience, but eventually, I had a brand-new cartridge installed.

The result? A faucet that worked like a charm without any drips or strange noises. And let me tell you, the sense of accomplishment I felt was second to none! So don’t be afraid to plunge and get your hands dirty. It’s worth it.

Home Remedy Fixes

After tackling the challenge of replacing a cartridge, I’ve understood the significance of DIY fixes in the plumbing world.

Sure, hiring a professional plumber is an option, but there’s something quite empowering about solving minor issues on your own. Let me share some home remedies I’ve learned over the years.

DIY Fixes for Common Issues

Like every home has its quirks, so does every plumbing system. But fret not! There are a few common issues that you can quickly fix with the right approach and tools.

Step-by-Step Instructions for Each Remedy

1. Sediment Buildup Removal

Sediment build-up in faucets can be a real headache. It slows down the flow of water and can even cause blockages. Here’s how I dealt with this:

  1. First, I turned off the water supply and opened the faucet to drain the remaining water.
  2. I unscrewed the faucet and removed the aerator (the part where the water comes out).
  3. I soaked the aerator in vinegar overnight to dissolve the sediment.
  4. The following day, I rinsed the aerator, screwed it back in, and voila! The water flowed like a dream.

2. Washer Replacement

When I first noticed my faucet leaking, I discovered the problem was a worn-out washer. Here’s how I replaced it:

  1. I started by shutting off the water supply.
  2. I then removed the faucet handle and packing nut, revealing the stem.
  3. I removed the stem, which allowed me to see the washer.
  4. After replacing the worn-out washer with a new one, I reassembled the faucet. No more leaks!

3. Air Bleeding Techniques

Air trapped in your pipes can cause some unsettling noises. One time, it sounded like my pipes were haunted! Here’s how I got rid of the air:

  1. I began at the highest faucet in my house and opened it along with the lowest faucet (usually found outside or in the basement).
  2. I then shut off the water supply.
  3. When water stopped flowing from the lowest faucet, I turned the water supply back on.
  4. I closed both faucets once the water started flowing out of the highest faucet.

Now, it’s your turn! Don’t be discouraged if you don’t get it right first. Remember, every master was once a beginner. Happy plumbing!

Preventative Maintenance

In my experience, prevention is better than cure, which is true for preventing faucet squealing.

I learned early on that regularly unscrewing and thoroughly cleaning the aerator keeps sediment at bay, helping prevent any whistling or squealing noises.

Applying food-grade silicone grease on moving parts also aids in smoother operation and noise reduction.

Creating a routine for regular faucet maintenance has been a game-changer for me. Every month, I dedicate time to checking all faucets for signs of wear and tear, cleaning aerators, and replacing worn-out washers.

This not only helps to prevent squealing but also extends the lifespan of my faucets.


In my plumbing adventures, I’ve discovered that the leading causes of faucet squealing are usually sediment build-up, worn-out washers, and air stuck in pipes.

These issues might sound intimidating, but trust me, they’re manageable at home with a bit of patience and elbow grease.

From soaking aerators in vinegar to replacing washers and bleeding off air, I’ve found that these simple home remedies are incredibly effective.

They’ve helped me fix the issues and saved me considerable money that would have otherwise gone to professional help.

While these DIY solutions have served me well, I strongly advocate for regular maintenance, as prevention is always easier than fixing.

Don’t hesitate to contact a professional if things seem out of your comfort zone. After all, there’s no harm in seeking help when it’s needed.

Keep learning, keep fixing, and remember every effort you put in contributes to your growth as a DIY enthusiast. Happy DIY-ing!
