Most of these repairs can be done at home in less than an hour. You don’t need to be a plumber, just someone willing to grab a wrench and follow a few simple steps. Let’s go through each problem and fix it one at a time.

1. How To Fix A Dripping Or Leaking Faucet

A faucet that keeps dripping is more than just annoying. It can waste gallons of water every day and slowly drive up your water bill. In most cases, the cause is a worn-out washer, O-ring, or cartridge. But if your faucet drips only at night, you might be dealing with fluctuating pressure, as explained in this fix for a faucet that drips at night but not during the day.

Here are the steps to fix a dripping or leaking faucet:

• Shut off the water supply under the sink using the valves.
• Remove the handle by popping off the top cap and unscrewing the handle screw.
• Take off the retaining nut to expose the cartridge or stem.
• Inspect the washer and O-ring. If they’re cracked, flattened, or brittle, swap them out for new ones.
• If your faucet uses a cartridge, pull it out and replace it with the same model.
• Reassemble the faucet and turn the water back on to test for leaks.

If it’s still dripping, the valve seat might be worn or corroded. You may need to clean or replace it using a valve seat tool.

2. How To Fix Low Water Pressure From Your Faucet

When your faucet barely lets out a stream, it’s usually because the aerator is clogged with mineral buildup or debris. This is especially common in homes with hard water, which is why many people prefer using kitchen faucets for hard water to reduce clogging and mineral buildup.

Here are the steps to fix low water pressure:

• Unscrew the aerator at the tip of the faucet. If it won’t budge, wrap it in a cloth and use pliers.
• Soak the aerator in vinegar for about 30 minutes to dissolve any buildup.
• Scrub it with an old toothbrush to remove leftover debris.
• Rinse and reattach the aerator, then test your faucet.

If the pressure is still low, check that the shut-off valves under the sink are fully open. If that doesn’t help, you might have a clogged supply line or an issue with the cartridge.

3. How To Fix A Handle That’s Hard To Turn

If your faucet handle feels stiff or grinds when you try to turn it, there’s likely mineral buildup inside the moving parts, an issue often avoided by using high-end kitchen faucets that resist wear over time.

Here are the steps to fix a hard-to-turn handle:

• Turn off the water supply before taking anything apart.
• Remove the handle by unscrewing the top and pulling it off.
• Take out the stem or cartridge underneath the handle.
• Soak the parts in vinegar to dissolve any mineral deposits.
• Apply plumber’s grease to the cleaned parts to help everything move smoothly.
• Replace the cartridge if it looks worn or corroded.
• Put the faucet back together and turn the water on to test the movement.

Once cleaned and lubed, the handle should turn smoothly without sticking.

4. What To Do If No Water Is Coming Out Of The Faucet

If nothing comes out when you turn on the faucet, don’t panic. It’s often caused by a blocked aerator, closed valve, or sediment stuck inside the faucet, especially if you’re using models with a metering cycle faucet mechanism, which controls water flow duration.

Here are the steps to fix a faucet with no water flow:

• Check the shut-off valves under the sink and make sure they are fully open.
• Unscrew the aerator and inspect it for blockages or buildup.
• Clean the aerator with vinegar, scrub it, and rinse it thoroughly.
• Disassemble the faucet body to check for sediment buildup inside the cartridge or valve.
• Soak any clogged parts in vinegar, rinse well, and reinstall them.
• Turn the faucet back on and test the flow.

If water still doesn’t flow, the problem may be with the supply lines or pipes, and you might need to call a plumber.

5. How To Fix A Faucet Leaking Around The Handle Or Base

If water is pooling around the handle or dripping from the base instead of the spout, it could be due to a failed seal or cartridge, like what’s explained in this case of a faucet leaking from the handle.

Here are the steps to fix a leaking faucet base or handle:

• Turn off the water supply before taking anything apart.
• Remove the handle and escutcheon (the decorative cover at the base).
• Inspect the O-rings and seals for cracks or wear.
• Replace any damaged O-rings with new ones of the same size.
• Check the mounting nuts under the sink and tighten them with a basin wrench.
• Wipe the area dry, reassemble the faucet, and test for leaks.

Leaks around the base can go unnoticed for a while, so fixing them early can prevent cabinet damage later.

6. How To Stop Strange Noises Coming From Your Faucet

Faucets shouldn’t make noise. If you hear whistling, banging, or screeching, it could be due to loose washers or high water pressure, a common reason why a faucet makes a loud humming noise.

Here are the steps to fix a noisy faucet:

• Turn on all faucets in your home for a few minutes to flush air from the pipes.
• Turn off the water and remove the faucet handle.
• Inspect and tighten any washers that seem loose or worn.
• Check the connections under the sink and tighten any loose pipe fittings.
• If you hear loud bangs when turning off the faucet, you might need to install a water hammer arrestor.

A noisy faucet may sound funny, but it could be a sign of pressure issues or loose parts that need attention.

7. How To Fix A Sprayer That’s Not Working

If your kitchen faucet sprayer won’t spray or has a weak stream, there might be a clog in the hose or the diverter valve isn’t working right.

Here are the steps to fix a faulty faucet sprayer:

• Unscrew the sprayer head and soak it in vinegar to remove buildup.
• Inspect the hose for kinks, cracks, or clogs, and clear or replace it if needed.
• Check the diverter valve (located inside the faucet body) and clean or replace it.
• Tighten any hose connections under the sink.
• Reassemble the sprayer and turn the water on to test.

If the sprayer still isn’t working after all that, replacing the entire sprayer unit might be the easiest solution.

8. How To Fix A Loose Or Wobbly Faucet

A faucet that wobbles every time you use it might seem harmless, but it can loosen more over time and eventually leak.

Here are the steps to fix a loose or wobbly faucet:

• Clear out the space under your sink so you can access the mounting hardware.
• Use a flashlight to find the mounting nuts that hold the faucet in place.
• Use a basin wrench to tighten those nuts carefully without overtightening.
• If the faucet still moves, apply a thin layer of silicone sealant around the base for extra support.
• Recheck the mounting after a day to make sure it’s still secure. If you’re installing a new faucet, it’s worth reviewing whether your sink setup is better suited for a widespread or centerset faucet and whether you need a 4-inch or 8-inch faucet configuration to match the mounting holes.

A stable faucet not only looks better but also helps prevent future leaks from loose connections.

Tools And Parts You’ll Need For DIY Faucet Repairs

You don’t need a garage full of tools to fix most faucet problems. A few common items from your toolbox (and maybe a quick trip to the hardware store) can take care of the job.

• Adjustable Wrench: Perfect for loosening or tightening faucet nuts without damaging the finish.
• Allen Wrenches: These come in handy for removing set screws from faucet handles, especially on modern models.
• Screwdrivers (Flathead and Phillips): You’ll need both types to remove screws, handles, and other parts.
• Replacement Washers and O-Rings: These are often the reason for drips and leaks. Keep a few common sizes on hand.
• Cartridges or Valve Stems: If your faucet uses a cartridge and it’s worn, replacing it can solve many stubborn issues.
• Plumber’s Grease: This helps lubricate moving parts and prevents squeaks or stiffness.
• White Vinegar: Great for soaking and removing mineral buildup from aerators and internal parts.
• Basin Wrench: Not always necessary, but very helpful when tightening nuts in hard-to-reach spots under the sink.

How To Know When It’s Time To Replace Your Faucet Instead

Some faucet problems just aren’t worth fixing over and over again. Here are signs it might be smarter to swap it out.

• Frequent Leaks: If you’ve replaced parts multiple times and it still leaks, the body might be cracked or worn.
• Rust or Corrosion: When you see rust or flakes inside or around the faucet, it’s likely breaking down inside too.
• Old and Outdated Design: Older faucets may not be compatible with modern cartridges or parts.
• Poor Water Pressure Despite Cleaning: If you’ve cleaned everything and still get poor flow, the issue could be internal corrosion.
• Loose or Wobbly No Matter What You Do: Some mounting points or faucet bases get too worn to fix properly.

Maintenance Tips To Prevent Faucet Problems Before They Start

A few small habits can help you avoid most faucet headaches down the road.

• Clean Aerators Every Month: Unscrew them and give them a vinegar soak to prevent clogs and mineral buildup.
• Turn Handles Gently: Yanking them can wear out washers and loosen parts faster.
• Check for Leaks Regularly: A quick look under the sink or around the faucet base once a month can help catch small drips before they cause bigger problems.
• Use a Water Softener If You Have Hard Water: Use a water softener if you have hard water. Hard water leaves behind mineral deposits that clog parts and reduce pressure. According to the U.S. Geological Survey, nearly 85% of homes in the U.S. have hard water, which can shorten the lifespan of your faucets and plumbing.
• Lubricate Moving Parts Once or Twice a Year: A little plumber’s grease goes a long way in keeping things moving smoothly.

When Should You Call A Professional Plumber?

Not every faucet issue needs a pro, but some definitely do. If you’ve tried the usual fixes and the problem keeps coming back, it may be time to get help.

A plumber can also catch issues that aren’t visible to the eye, like pipe corrosion or water pressure problems inside the wall. If your faucet is leaking into your cabinet or making loud banging noises when turned off, don’t wait too long. These can lead to water damage or expensive repairs.

And if you’re replacing an old faucet and run into odd fittings, shut-off valve problems, or just feel stuck, calling a professional can save you hours of frustration and extra trips to the store. Sometimes peace of mind is worth it.

Conclusion

Faucets don’t need to be a mystery. Drips, weak flow, stiff handles, or noisy parts usually come down to just a few common issues. With some patience, the right tools, and a little guidance, you can handle most repairs yourself.

Keep an eye on your faucet’s performance and take care of small problems before they grow. Regular cleaning and gentle use also go a long way. And remember, when things feel over your head, calling a professional is always a smart move.
