A leaky faucet is a common household issue that can waste water and increase utility bills if ignored. In most cases, the problem is caused by worn-out washers, O-rings, or loose internal parts.
To fix it, first turn off the water supply. Then disassemble the faucet handle carefully and inspect the internal components. Replace any damaged washer or O-ring, clean the parts, and reassemble the faucet tightly. After turning the water back on, check for any remaining leaks.
With basic tools and a little patience, this simple repair can usually be done at home without needing a professional.
