To stop an under-sink plumbing leak, start by placing a bucket underneath to catch wastewater, then identify whether the leak originates from loose slip-joint nuts, worn washers on the P-trap, or a corroded tailpiece. Hand-tighten any loose slip-joint nuts. If the leak persists, unscrew the fittings, replace the degraded rubber washers inside the slip joints, wrap Teflon tape around threaded connections if necessary, and reassemble. Callout type="warning" title="Hygiene Warning": Place a bucket under the P-trap before loosening slip-joint nuts to catch stagnant wastewater. Verification: Run the faucet at full pressure to ensure all under-sink connections remain completely dry.
