• Faucet Base or Spout: Worn-out O-rings, loose mounting nuts, or a cracked internal cartridge.

• Drain Strainer: Failed plumber’s putty or a loose large nut right under the sink basin.

• P-Trap and Pipes: Loose slip nuts, misaligned plastic connections, or split rubber washers.

• Supply Lines: Old shut-off valves or worn gaskets on flexible water hoses.

Quick Fix Steps

• Turn off water: Locate the shut-off valves under the sink and turn them clockwise if the leak is from the faucet or supply lines.

• Dry the area: Wipe all pipes and surfaces completely dry with a towel, then place dry paper towels underneath to easily spot where new water drips first.

• Tighten loose parts: Hand-tighten slip nuts on plastic drain pipes or use pliers very gently for a quarter-turn if they drip.

• Replace worn seals: Swap out flat rubber washers, split O-rings, or re-apply plumber’s putty under the basket strainer if tightening fails.
