To address a broken household faucet, first locate and close the water shut-off valve beneath the sink or near the main water supply. If the valve is inaccessible, shut off the main water supply to the house. Drain excess water from the pipes using a bucket. Next, disconnect the faucet handle and remove the stem or cartridge to inspect for damage. Replace worn parts like O-rings, washers, or cartridges. If the faucet leaks but turns on normally, adjust the seat washer or stem. Reassemble the faucet and test for functionality. If the issue persists or involves complex components, contact a licensed plumber.

This approach ensures safety by preventing water damage and potential mold growth. According to the Environmental Protection Agency (EPA), fixing a dripping faucet can save up to 10 gallons of water daily, equivalent to 3,650 gallons annually per household. A 2022 study by the National Association of Home Builders found that 70% of faucet leaks can be resolved through DIY repairs, reducing costs by 60% compared to professional service. The average cost of a DIY repair is $50–$100, while professional service ranges from $150–$300. Additionally, the EPA notes that及时 addressing leaks prevents water waste, which accounts for 1% of total U.S. household water use. Proper shut-off valve use minimizes flood risks; the Insurance Institute for Property Loss Prevention reports that 20% of water-related claims stem from unaddressed leaks. Regular maintenance of faucet components, such as O-rings and cartridges, extends appliance lifespan by up to five years. However, complex issues like broken pipes or electrical malfunctions require expert intervention to avoid further damage. Ultimately, combining immediate action with preventive measures ensures efficient and cost-effective resolution of faucet problems.
