Repairing leaky faucets involves turning off the water supply, identifying the type of faucet, inspecting the faucet for visible damage or wear, replacing the washer, and possibly replacing other parts like the O-ring, cartridge or valve seat. After reassembling the faucet and turning the water supply back on, test the faucet for leaks. If the problem persists, it’s best to seek the advice of a professional plumber.
