A leaky faucet can quickly become a huge annoyance as well as lead to higher water bills and potential water damage if ignored.
While the persistent drip-drip-drip may tempt you to call a plumber right away, many common faucet leaks can be fixed by DIYers with a little know-how.
Don’t be intimidated by basic faucet repair - you can likely handle it yourself. With the right techniques and tools, you can diagnose problems, fix leaks, and get your faucets working like new again.
Read on to learn how to repair a leaky faucet like a pro.
1. Identify the Leak Source

The first step in any faucet leak repair is determining where exactly the drip or seepage is coming from. Analyzing the leak pattern will point you to the faulty part.
- Drips at the faucet spout outlet: This indicates an issue with the aerator or cartridge/valve seals inside the faucet body allowing water through.
- Leaks around the base of the faucet spout: Check the spout connection to the faucet body and any O-rings/gaskets sealing the two components.
- Moisture at the point where the faucet mounts to the sink: Look at the nuts and bolts anchoring the faucet as well as any gaskets meant to seal the faucet-to-sink junction.
- Water under the handle: Worn O-rings around the cartridge stem are likely allowing water through the handle-to-valve connection.
Once you’ve identified the source, you can narrow down the repair process.
2. Clean or Replace the Aerator
If you're experiencing drips directly from the faucet spout itself, an inexpensive aerator replacement or cleaning may solve your problem. Start by unscrewing the aerator from the faucet spout tip. Inspect the screen and flow restrictor inside for any debris or mineral deposits that could be obstructing proper water flow and causing drips.
Soak the entire aerator in white vinegar overnight to dissolve any built-up limescale or hard water deposits. Gently scrub with an old toothbrush if needed to loosen clogs. Ensure none of the fine screen mesh is damaged before reinstalling the aerator. Also examine any O-rings or gaskets and replace them if worn. When reattaching the aerator, make sure to seat it properly to create a tight seal. Solve many frustrating drips this way at a fraction of the cost of a full faucet repair.
3. Replace Worn Washers and O-Rings

If drip problems persist after cleaning the aerator, the next step is replacing any worn rubber O-rings or seals farther inside the faucet assembly. Both cartridge and compression faucets rely on small O-rings and washers to create water-tight seals between moving components. Over time, these rubber pieces flatten and crack, leading to drips and leakage.
Replacement kits with new pre-sized O-rings and washers are available at any hardware store for a few dollars. Start by shutting off hot and cold water supply valves and then disassembling the handles and valve components according to manufacturer instructions (repair manuals can often be found online).
Look for worn O-rings around the cartridge cylinder or flattened washers inside valve seats. Apply a small amount of plumber’s grease or petroleum jelly to new O-rings and washers before inserting to allow smooth motion and tight seal.
Reassemble properly and test water flow. With this simple repair, you can stop leaks at the source.
4. Tighten Faucet Mounting Connections
If you see water dripping around the base of the faucet spout where it connects to the sink or countertop, the problem is likely loose mounting nuts and bolts. These connections can gradually loosen over time from vibrations and temperature fluctuations, especially with plastic (rather than metal) nuts.
Tightening mounting hardware restores a secure faucet-to-sink connection and watertight seal. Start by fully disconnecting supply lines and shutting off water valves. Examine any rubber gaskets around the faucet base and replace if visibly warped or worn.
Use an adjustable wrench or basin wrench to tighten the nuts around the faucet shank underneath in a crossing “X” pattern. Reconnect supply lines and turn water back on to test for leaks before reinstalling sink plumbing covers. Calling a plumber can be avoided with this easy DIY fix in minutes.
5. Adjust or Replace Supply Hoses

Faulty supply hoses connecting the faucet to your water supply valves under the sink are another potential culprit for leaks. The most reliable and durable faucet supply tubes are made of braided stainless steel. Plastic supply tubes are prone to cracking and bursting over time.
Inspect your supply hoses for any bulging or cracks indicating damage. Also look for corrosion around ends. Replace damaged plastic supply tubes with higher quality braided stainless steel hoses.
Ensure any rubber gasket washers inside the female hose ends are in good shape to prevent leaks - replace if worn. Use pliers to tighten connections an extra quarter turn past hand tight. Keep supply hoses in top shape to avoid leakage at water inlets.
6. Update Interior Faucet Components
If you’ve cleaned and replaced all the gaskets and seals but your faucet still drips, the interior faucet components themselves may need replacement due to wear, sediment buildup, or corrosion. Cartridges, valve seats, stems, and supply tubes wear out over years of use. A full interior faucet component replacement kit runs about $35-$50 and comes with all necessary parts.
Follow the manufacturer repair guide when removing old valves and cartridges. Soak any scaled parts in vinegar solution but don’t scrape surfaces.
Lubricate new seals and O-rings with plumber’s grease and reinstall components in the proper order. Taking apart the faucet interior is a more advanced project but allows you to restore everything to like-new condition.
7. Troubleshoot Specialty Faucet Types

Some more complex faucet systems like pull-out or touch-activated models require specialized repair techniques.
Pull-out/pull-down sprayer faucets
- Clean lime and sediment from the pull-out nozzle using vinegar and small brushes. Ensure interior check valves are seated properly and not damaged.
- Replace any torn or worn supply line hoses connecting the sprayer spout.
- Adjust the docking collar if the spray head doesn’t retract fully and seal into spout.
Touch-activated faucets
- Clean sensor “eye” window of any water deposits or dirt buildup interfering with motion activation.
- Replace leaky solenoid valves inside the faucet body.
- Reboot touch activation system by shutting off hot/cold water lines briefly to reset.
Knowing the right repairs for specialty faucets prevents having to replace the entire high-tech fixture for a minor issue.
8. When to Call a Plumber for Faucet Repairs
While the majority of basic faucet leak repairs are manageable as DIY projects for homeowners, more complex issues should be left to professional plumbers -
- Faucet leaks requiring full sink or countertop removal to access interior components
- Major scale buildup necessitating complete faucet disassembly or acid bath
- Centralized leaks inside bathroom or kitchen walls requiring internal pipe access
- Whole home water pressure issues unrelated to a single faucet
- Major damage from frozen burst pipes, floods, etc.
- Installation of brand new faucet fixtures
Know your limits and when to call the pros! But for most standard kitchen and bathroom faucet leaks, implementing these DIY repair techniques will have you solving those dripping problems in no time and save you money. Learn to fix faucets like a seasoned pro!

Repairing a current faucet leak is one thing, but preventing leaks in the first place should be your goal. Applying these simple maintenance principles will maximize your faucet’s lifespan and minimize repair frequency:
- Inspect regularly for early signs of wear, corrosion, cracking on parts. Address promptly!
- Disassemble and lubricate inner valves/stems annually using plumber's grease. Keeps o-rings supple.
- Clean faucet exterior and aerator screens monthly using vinegar solution and small brushes. Prevent mineral scale buildup.
- Follow manufacturer directions for replacing cartridges, washers, O-rings on schedule. Don't wait for failure.
- Ensure sink/countertop mount connections stay tight. Tighten mounting nuts/screws if any drips.
- Replace plastic supply tubes with braided stainless steel hoses to prevent cracking/leaks.
- Insulate pipes and interior valves in very cold climates to avoid freeze damage.
With diligent preventative maintenance on your faucets, you can avoid the annoyance and cost of unexpected leaks for years to come. An ounce of prevention is truly worth a pound of cure when it comes to plumbing! Implement a routine faucet care regimen to maximize their lifespan.
10. High Quality Faucets Reduce Leak Risk
Another component of leak prevention is investing in higher quality faucets in the first place, like those from top brands such as Moen, Kohler, Delta, American Standard, Grohe, and Jaquar. Here are material and design factors that increase faucet durability and leak resistance:
- All brass or stainless steel bodies rather than lower grade metals. Avoid plastic parts.
- Ceramic disc valve cartridges over older compression style valves. Lasts 5x longer.
- Reinforced PVD coatings on finishes resist corrosion and scratches.
- Silicone/EPDM washers, gaskets and O-rings rather than cheap rubber. Maintain suppleness longer.
