Steps to Repair a Leaky Faucet

To repair a leaky faucet, first turn off the water supply by locating the shut-off valves under the sink and closing them clockwise. Place a bucket beneath to catch drips, then use an adjustable wrench to remove the faucet handle by loosening the screw and lifting it off. Inspect the internal components, such as the washer or O-ring, which are often the cause of leaks due to wear.

Key Components and Common Causes

Faucets typically consist of a handle, cartridge or stem, washer, O-ring, and aerator. Leaks commonly result from worn-out washers, corroded seats, or loose connections. For compression faucets, replace the rubber washer; for cartridge types, swap the entire cartridge. Always clean mineral buildup with vinegar to prevent recurring issues.

Practical Example: Fixing a Kitchen Faucet

Consider a standard kitchen compression faucet dripping from the spout. After shutting off the water, remove the handle and unscrew the packing nut to access the valve seat. Use pliers to pull out the old stem, replace the worn washer with a new one matching the size (usually 1/2-inch), and reassemble tightly. Test by turning the water back on; the drip should stop if the seal is proper.

Importance of Timely Repairs

Repairing a leaky faucet conserves water, potentially saving hundreds of gallons annually and reducing utility bills. It prevents mold growth and structural damage from constant moisture. Regular maintenance extends fixture lifespan and promotes sustainable home care practices.
