How to Fix a Leaky Faucet Without Calling a Plumber
A dripping faucet may seem like a minor annoyance, but over time it can waste gallons of water and increase your utility bill. The good news? Fixing a leaky faucet is one of the easiest DIY plumbing tasks you can tackle—no expensive service call required. Whether you live in a townhouse in Waldorf or a condo in DC, this step-by-step guide will help you stop that leak quickly and safely.
What You'll Need:
Adjustable wrench
Flathead and Phillips screwdrivers
Replacement washers or cartridges (available at hardware stores)
Plumber’s grease or petroleum jelly
Towel or rag
Bowl or container to catch water
Step 1: Turn Off the Water Supply
Look under the sink and locate the shut-off valves. Turn them clockwise to stop the flow of water to the faucet. Then, turn the faucet on to drain any remaining water in the line.
Step 2: Plug the Drain
Use a sink plug or place a towel in the drain to prevent small parts from falling in while you work.
Step 3: Disassemble the Faucet Handle
Use a flathead screwdriver to remove the decorative cap from the top of the faucet handle. Underneath, you’ll find a screw—remove it with a screwdriver, then gently pull off the handle.
Step 4: Identify Your Faucet Type
There are several types of faucets—compression, cartridge, ball, and ceramic disc. The most common for residential homes are compression and cartridge faucets. Compression faucets typically have two separate handles, while cartridge faucets often have a single handle.
Step 5: Remove and Inspect the Internal Parts
For a compression faucet:
Use a wrench to loosen the packing nut.
Remove the stem and inspect the rubber washer at the bottom. If it’s worn, cracked, or stiff, replace it.
For a cartridge faucet:
Pull out the cartridge using pliers if necessary.
Check for cracks or mineral buildup. Replace it if damaged.
Take the old washer or cartridge to your local hardware store to ensure you buy an exact match.
Step 6: Apply Plumber’s Grease
Before reassembling, apply a small amount of plumber’s grease to the new washer or cartridge to help it seat properly and prevent future leaks.
Step 7: Reassemble the Faucet
Reinsert the stem or cartridge, tighten any nuts, and reattach the handle and screw. Finish by snapping the decorative cap back into place.
Step 8: Turn the Water Supply Back On
Slowly turn the shut-off valves counterclockwise to restore water. Turn on the faucet to check for leaks—your fix should be complete.
When to Call a Plumber
If your faucet continues to leak after replacing the washer or cartridge, or if you're dealing with a more complex faucet type (like a ceramic disc model), it may be time to consult a professional.
Save Water, Save Money
Fixing a leaky faucet is a simple task that can make a noticeable difference in your home’s efficiency. Small maintenance jobs like these not only reduce waste but also add to your property’s long-term value.
