You’re standing at your kitchen sink, ready to tackle a mountain of dishes, when you notice something’s off. The water flow just isn’t what it used to be. Maybe it’s spraying in all directions, or barely trickling out at all. Many people face this frustrating situation. Your kitchen sink aerator might be the culprit, and fortunately, it’s often an easy fix.
Let’s get to the bottom of this annoying problem. We’ll explore why your kitchen sink aerator might be acting up and walk you through some simple solutions you can try at home. You might just save yourself a call to the plumber and feel pretty handy in the process.
Kitchen Sink Aerator Not Working: Common Causes
Before we start fixing your stubborn aerator, let’s take a closer look at what might be causing the trouble in the first place. Understanding the root of the problem can help you tackle it more effectively and even prevent future issues.
1. Mineral Buildup
Have you noticed a white, chalky substance around your faucets? That’s mineral buildup, and it’s one of the most common culprits behind aerator issues. Over time, minerals in your water (especially if you have hard water) can accumulate in the tiny holes of your aerator. This buildup slowly clogs these openings, restricting water flow or causing it to spray erratically.
The tricky thing about mineral buildup is that it happens gradually. You might not notice a problem until the aerator is significantly clogged. Regular cleaning can help prevent this issue, but if you’ve never cleaned your aerator before, there’s a good chance this is what’s causing your troubles.
2. Debris in the Aerator
Your kitchen sink sees a lot of action, and sometimes, small bits of debris can find their way into your aerator. This could be anything from tiny food particles to small pieces of plastic or rubber that have broken off from other items. While the aerator is designed to catch these particles and prevent them from spraying out of your faucet, over time, they can accumulate and cause blockages.
If you’ve recently done any plumbing work or if there’s been construction in your area that affected the water supply, you might notice this problem more acutely. Sometimes, small bits of pipe sediment can get dislodged and end up in your aerator.
3. Worn-out Washer
Inside your aerator, there’s a small rubber washer that helps create a tight seal. Like any rubber component, this washer can wear out over time. When it does, it can affect how water flows through the aerator. A worn-out washer might cause leaks around the edges of the aerator or contribute to uneven water flow.
This issue is more common in older faucets or in homes where the water pressure is particularly high. The constant stress on the washer can cause it to degrade faster than you might expect.
4. Incorrectly Installed Aerator
If you’ve recently replaced your aerator or if someone else has worked on your faucet, there’s a chance the aerator wasn’t installed correctly. An aerator that’s cross-threaded or not screwed on tightly enough can cause all sorts of flow problems.
Sometimes, people make the mistake of installing the aerator upside down. While it might seem like a simple part, aerators are designed to be installed in a specific orientation to work properly.
5. Damaged Aerator
While aerators are generally durable, they’re not indestructible. If your aerator has been bumped hard by a heavy pot or if it’s been subjected to extreme temperatures, it might have sustained some damage. Cracks or warping in the aerator housing can lead to weird spray patterns or reduced flow.
Sometimes, the internal components of the aerator, like the flow restrictor or the mixer, can become damaged. This often results in water flow that’s either too strong or too weak, regardless of how you adjust your faucet handles.
Now that we’ve covered the most likely causes of your aerator woes, let’s move on to how you can fix these issues and get your kitchen sink flowing smoothly again.
Kitchen Sink Aerator Not Working: How to Fix
Alright, now that we know what might be causing your kitchen sink aerator to misbehave, let’s roll up our sleeves and get to work. Don’t worry if you’re not a DIY expert – these fixes are straightforward enough for most homeowners to tackle. Just take it step by step, and you’ll have that sink working like new in no time.
1. Remove and Clean the Aerator
The first and often most effective fix is to give your aerator a good cleaning. Here’s how:
Start by unscrewing the aerator from the faucet. You might be able to do this by hand, but if it’s stubborn, wrap a cloth around it to protect the finish and use pliers to gently loosen it.
Once it’s off, take a good look at it. You’ll probably see some gunk built up in there. Soak the aerator in white vinegar for a few hours or overnight. This will help dissolve any mineral deposits.
After soaking, use an old toothbrush to gently scrub away any remaining debris. Pay special attention to the small holes where the water comes out.
Rinse the aerator thoroughly under running water. If you have a pin or needle handy, you can use it to poke through any holes that still seem clogged.
Once it’s clean, simply screw it back onto your faucet. Make sure it’s on tight, but don’t overdo it – you don’t want to damage the threads.
2. Replace the Washer
If cleaning didn’t do the trick, the problem might be with the washer. Here’s how to replace it:
After removing the aerator as described above, look for a small rubber washer inside. It might be stuck to the aerator or sitting loose inside.
Remove the old washer. You might need tweezers if it’s stubborn.
Take the old washer to a hardware store to find an exact replacement. These washers come in different sizes, so matching it is important.
Place the new washer in the same spot as the old one. Make sure it’s seated properly.
Screw the aerator back onto the faucet, again being careful not to overtighten.
3. Check for Correct Installation
Sometimes, the problem is as simple as the aerator not being installed correctly. Here’s what to check:
Remove the aerator and look at how it’s designed. There’s usually a right way up – the side with more holes typically faces down.
Make sure you’re not cross-threading the aerator when you screw it back on. It should turn easily. If you feel resistance right away, back it off and try again.
Tighten the aerator by hand first. Only use pliers if necessary, and when you do, protect the finish with a cloth.
4. Flush Out the Faucet
Sometimes, debris can be lurking in your faucet, ready to clog your aerator as soon as you clean it. Here’s how to flush it out:
Remove the aerator from your faucet.
Place a clean cloth over the drain to catch any debris.
Turn on both the hot and cold water full blast for about a minute. This should flush out any loose particles in your pipes.
After flushing, clean your aerator again (following the steps in fix #1) before reinstalling it.
5. Replace the Aerator
If none of the above fixes work, it might be time to replace the entire aerator. Don’t worry, this is still a simple and inexpensive fix:
Remove the old aerator as described earlier.
Take it to a hardware store to find a matching replacement. Aerators come in different sizes and styles, so having the old one with you ensures you get the right fit.
Screw the new aerator onto your faucet, again being careful not to overtighten.
If you’re unsure about the size or type of aerator you need, many hardware stores have knowledgeable staff who can help you find the right match.
If you’ve tried all these fixes and you’re still having issues, or if you run into any problems you’re not comfortable handling, it’s time to call in a professional plumber. They have the tools and expertise to diagnose and fix more complicated issues that might be affecting your sink’s performance.

FAQs
How often should I clean my kitchen sink aerator?
It’s a good idea to clean your kitchen sink aerator every 3-6 months. If you have hard water, you might need to do it more frequently to prevent mineral buildup.
Can a faulty aerator cause low water pressure in my whole house?
No, a faulty aerator only affects the faucet it’s attached to. If you’re experiencing low water pressure throughout your house, you likely have a different issue that requires professional attention.
Is it normal for water to spray out the sides of the aerator?
No, water spraying out the sides usually indicates the aerator isn’t properly installed or the washer is worn out. Try reinstalling it or replacing the washer.
Can I use CLR or other chemical cleaners on my aerator?
While CLR and similar products can be effective, they can also be harsh. It’s best to start with vinegar, which is gentler. If that doesn’t work, you can try stronger cleaners, but be sure to rinse thoroughly afterwards.
My faucet doesn’t have a visible aerator. Does this mean it doesn’t have one?
Some modern faucets have hidden or integrated aerators. If you can’t see one, check your faucet’s manual or contact the manufacturer to learn how to access and clean it.
