A leaky kitchen faucet is more than just an annoyance—it wastes water, increases utility bills, and can even cause damage to surrounding countertops if left untreated. Fixing the issue is usually straightforward once the cause is identified. Below is a professional step-by-step guide.
Worn Out Washer: Over time, washers inside the faucet wear down, creating gaps that allow water to seep through.
Damaged O-Ring: The O-ring provides a seal around moving parts. When cracked or loose, it results in leakage near the handle.
Cartridge Issues: Cartridge-style faucets may leak if the cartridge becomes clogged or damaged.
Corroded Valve Seat: Corrosion at the connection between faucet and spout can lead to persistent dripping.
Locate the shutoff valves under the sink and turn them clockwise to stop water flow. This prevents accidental flooding during the repair.
Remove the decorative cap, then unscrew and lift off the handle. Use the appropriate tool (Allen wrench or screwdriver) depending on your faucet model.
Take out the stem or cartridge. Examine the washer or O-ring for wear, cracks, or deformation. Replace with a new component of the correct size.
If the leak persists, inspect the cartridge or valve seat. Clean away mineral deposits or replace the part if it shows signs of corrosion or damage.
Reinstall the faucet components in reverse order. Slowly turn on the water supply and test the faucet to ensure the leak has been fixed.
Always use manufacturer-recommended replacement parts to ensure compatibility.
Apply plumber’s grease to new O-rings or washers for a secure seal and smoother operation.
If leaks continue after replacement, it may indicate a deeper issue requiring professional inspection.
Fixing a leaky kitchen faucet requires identifying the cause—whether it’s a worn washer, faulty O-ring, or corroded valve seat—and replacing the faulty part. With proper tools and care, most leaks can be resolved quickly, restoring both efficiency and reliability to your kitchen.
