Leaks is one of the most common faucet faults. It occurs when water escapes from the faucet, usually due to a worn out washer or seal. Clogs are another common faucet fault, which occur when debris or sediment builds up in the faucet and prevents water from flowing properly. Drips are also a common faucet fault, which occur when the faucet is not completely shut off, allowing water to slowly drip out. Finally, corrosion is another faucet fault, which occurs when the metal parts of the faucet become corroded and no longer function properly.
