Leaky Sink Repair: Two Common Fixes
Case 1: The Dripping Faucet (Step-by-Step Faucet Repair)
This is the most common type of leak, usually caused by a worn-out washer or O-ring inside the faucet handle. Here’s how to fix a leaky sink in this situation.
Phase 1: Preparation
Preparation: Turn off the water supply to the sink. This is a critical first step for any leaky sink repair. You can find the shut-off valves under the sink. Turn them clockwise until they are tight. If you don’t have valves, you’ll need to shut off the main water supply to your home.
Phase 2: Disassembly
Open the faucet to drain any remaining water. Use a screwdriver to remove the faucet handle. You’ll likely see a screw hidden under a decorative cap. Once the screw is removed, you can lift off the handle to expose the valve stem and O-ring.
Phase 3: The Repair
Use your adjustable wrench to unscrew the valve stem. Inside, you’ll find the worn-out washer or O-ring. Remove it and replace it with a new one of the exact same size. Take the old one to the hardware store if you’re not sure which size to buy.
Phase 4: Reassembly and Testing
Screw the valve stem back into place. Reattach the handle and turn the water supply back on. Test the faucet by turning it on and off a few times to ensure the drip has stopped. If you notice a leak around the base, you may need to apply a small amount of plumber’s tape to the threads.
Case 2: The Under-Sink Leak (Fixing Pipes and Connections)
Leaks under the sink are often more serious, as they can cause water damage and mold. They are usually caused by a loose connection or a corroded pipe. Fixing an under-sink leaky sink repair requires careful diagnosis.
Phase 1: Diagnosis
First, place a bucket under the leak. Use a flashlight to trace the leak to its source. The leak may be coming from a loose nut, a compromised P-trap, or a damaged section of pipe.
Phase 2: Disassembly and Repair
Use an adjustable wrench to tighten any loose connections. If the pipe itself is damaged, you will need to replace the damaged section. This may require cutting the pipe with a saw and using a new connector.
Phase 3: Reassembly and Testing
Hand-tighten all connections first, then use your wrench for a final quarter-turn. Test the connections by running water through the sink. If the leak persists, you may need to call a professional plumber to prevent extensive water damage and mold growth.
