Is your faucet making strange squeaking or squealing noises every time you turn it on? A squeaky faucet can drive you crazy with its high-pitched screeching. Luckily, fixing a noisy faucet is usually a quick and easy DIY job that doesn’t require any fancy tools.
In this comprehensive guide, you’ll learn why faucets squeak, how to diagnose the problem, and step-by-step instructions for lubricating the faucet to stop the annoying squeak for good.
What Causes a Faucet to Squeak?
A squeaky faucet is usually caused by friction from a lack of lubrication around the faucet handle stem. This metal stem is located inside the faucet body and sits under the handle you turn. It controls the on/off function and water flow.
When the faucet is turned on, the handle pulls up the stem, which lifts the washer at the bottom of the stem to allow water to flow. A lack of lubrication around the stem allows metal parts to rub together, creating that irritating squeaking noise.
Other potential causes of a noisy faucet include:
- Worn out rubber washers or O-rings that need replacing
- Mineral buildup and corrosion around the stem from hard water
- A loose handle that needs tightening
But in most cases, a good lubrication is all that’s needed to fix a squeaky faucet.
How to Diagnose the Problem
Before you can fix the squeak, you need to confirm it’s caused by a lack of lubrication rather than a larger underlying issue.
Here are two easy ways to diagnose the problem:
1. Remove the Faucet Aerator
The first step is to unscrew and remove the aerator. This is the small screen-like piece located at the tip of the faucet spout.
Examine the aerator to make sure it’s not clogged with mineral deposits. A clogged aerator can restrict water flow and potentially cause squeaking noises.
If it’s clogged, soak the aerator in vinegar to dissolve any buildup, then rinse and reattach. Turn the faucet back on to see if removing any clog fixed the squeak.
2. Wiggle the Handle
With the aerator removed, turn the faucet handle on and wiggle it from side to side.
If the squeak disappears briefly while wiggling, the noise is likely due to friction around the faucet stem and just needs lubrication.
If the squeak persists while wiggling, the issue may be more complex, like worn washers or O-rings that need replacing.
How to Fix a Squeaky Faucet
Once you’ve confirmed the squeak is coming from lack of lubrication, fixing it is a breeze. Here are the steps:
Things You’ll Need
- Rag
- Needle-nose pliers
- Screwdriver
- Plumber’s grease
Step 1: Turn Off Water Supply
Start by shutting off the water supply valves under the sink. Turning the knob clockwise until it stops will prevent water from spurting out when you remove the faucet handle.
Step 2: Pry Off the Faucet Cap
The cap is the decorative cover that sits on top of the handle and conceals the screw. Insert a flat head screwdriver under the edge of the cap and gently pry it off.
This may require some force, but take care not to damage the cap.
Step 3: Remove the Faucet Handle
With the cap removed, use a screwdriver to loosen the screw holding the handle in place. Turn it counterclockwise to unscrew.
This will allow you to lift off the faucet handle and access the stem.
Step 4: Clean and Lubricate the Stem
Use a rag to wipe away any dirt or buildup on the stem and inside the faucet body.
Then apply a small amount of plumber’s grease or petroleum jelly to the stem and the rubber O-ring near the base. This lubrication will allow the components to glide smoothly rather than squeak.
Step 5: Reattach Handle and Turn Water Back On
Place the faucet handle back over the stem and tighten the screw to hold it in place.
Put the decorative cap back on top of the handle. Turn the water supply back on and give the faucet a test turn. It should now operate quietly without any squeaking!
When to Call a Plumber
While a lack of lubrication is the most common cause of a noisy faucet, there are times when the problem requires a professional plumber:
- If the squeak persists after lubricating the stem
- If you can’t remove the handle due to a stripped screw
- If the leak is accompanied by low water pressure
- If you notice signs of cracks, corrosion, or damage
A plumber has specialized tools and expertise to fully diagnose the problem and make repairs beyond just lubrication.
Preventing Future Squeaks
Lubricating the faucet stem is only a temporary fix for squeaks. The grease will eventually wear off, and you’ll need to repeat the lubrication process every 6-12 months.
To prevent frequent squeaking, upgrade to new faucet washers and O-rings when you notice them becoming worn out. Use a water softener if you have hard water, which can accelerate wear and tear.
And give your faucets a regular once-over to spot potential problems before they turn into annoying squeaks. A little preventive maintenance goes a long way!
FAQs About Noisy Faucets
Here are answers to some frequently asked questions about fixing squeaky faucets:
What type of lubricant should I use?
Plumber’s grease works best since it’s designed for faucet valves. Petroleum jelly is a good alternative. Avoid using regular greases or oils.
How do I remove the handle if the screw is stuck?
Try gripping it tightly with pliers or locking pliers. If it won’t budge, you may need to drill it out or use a screw extractor.
Why does my faucet still leak after lubricating?
The leaks likely mean worn out washers or O-rings. These rubber seals will need to be replaced to fully fix the drip.
What should I do if the handle is stuck in place?
Spray lubricant around the base of the handle and let it soak in for 5-10 minutes. Then try gently tapping the handle with a hammer or mallet while turning it.
Can I just replace the whole faucet?
Yes, if lubrication and new washers don’t fix the squeak, replacing the entire faucet may be your best option.
In Summary
Dealing with a constantly squeaky faucet can make you feel like you’re losing your mind. Luckily, a little DIY troubleshooting combined with some simple lubrication in most cases can get your faucet back to quietly functioning in no time.
To recap, follow this process:
- Remove the aerator and check for clogs
- Wiggle the handle while water is running to isolate the source
- Shut off water supply and pry off the decorative cap
- Unscrew the handle and lubricate the stem and washers
- Reattach handle and turn water back on to test
Knowing how to fix a squeaky faucet yourself will save you the hassle and expense of multiple plumber visits. Just be sure to lubricate regularly to prevent future squeaks. And replace worn parts promptly when needed to keep your faucets in tip-top shape.
