A leaky faucet is a common plumbing issue where water drips or flows from the faucet even when it is turned off. This problem can occur due to worn-out washers, damaged O-rings, or corroded valve seats. Over time, these components can degrade, leading to water waste and increased utility bills. Fixing a leaky faucet typically involves disassembling the faucet, replacing the faulty parts, and reassembling it. Regular maintenance can help prevent leaks and extend the lifespan of the faucet. Addressing leaks promptly is important for conserving water and maintaining a functional plumbing system.
