How to Fix a Leaking Sink

Introduction

A leaking sink can be a significant inconvenience in your home. Not only does it waste water, but it can also lead to costly water damage and mold growth. Fortunately, fixing a leaking sink is not as difficult as it may seem. In this article, we will show you how to fix a leaking sink with easy-to-follow steps.

Step 1: Turn Off the Water Supply

Before you begin fixing the sink, it’s essential to turn off the water supply. The shut-off valve is usually located beneath the sink. Turn off the valve by turning it clockwise until it stops. If you cannot locate the shut-off valve, turn off the main water supply to your home.

Step 2: Remove the Sink Stopper

The sink stopper needs to be removed to access the sink drain. Pull up the stopper and unscrew the pivot rod that holds it in place. Once the stopper is removed, use pliers to remove any hair or debris from the drain.

Step 3: Inspect the Sink Drain

Inspect the sink drain for any signs of damage, such as cracks or corrosion. If the drain is damaged, it may need to be replaced. If the drain is in good condition, move on to the next step.

Step 4: Tighten the Sink Drain

If the sink drain is loose, it may be the cause of the leak. Use pliers to tighten the locknut that holds the drain in place. Be careful not to overtighten the nut, as this can cause damage to the sink.

Step 5: Replace the Sink Gasket

If the sink gasket is worn or damaged, it may be the cause of the leak. Remove the old gasket and replace it with a new one. Be sure to apply plumber’s putty around the gasket to create a watertight seal.

Step 6: Replace the Sink Flange

If the sink flange is damaged, it may need to be replaced. Remove the old flange and replace it with a new one. Be sure to apply plumber’s putty around the flange to create a watertight seal.

Step 7: Inspect the Sink Faucet

Inspect the sink faucet for any signs of damage, such as cracks or corrosion. If the faucet is damaged, it may need to be replaced. If the faucet is in good condition, move on to the next step.

Step 8: Tighten the Faucet Base

If the faucet base is loose, it may be the cause of the leak. Use a wrench to tighten the mounting nuts that hold the faucet in place. Be careful not to overtighten the nuts, as this can cause damage to the sink.

Step 9: Replace the Faucet O-Ring

If the faucet O-ring is worn or damaged, it may be the cause of the leak. Remove the old O-ring and replace it with a new one. Be sure to apply plumber’s grease to the O-ring to ensure a proper seal.

Step 10: Replace the Faucet Cartridge

If the faucet cartridge is worn, it may be the cause of the leak. Remove the old cartridge and replace it with a new one. Be sure to turn off the water supply before replacing the cartridge.

Step 11: Reassemble the Sink

Once you have completed the necessary repairs, reassemble the sink. Replace the sink stopper and pivot rod, and tighten any remaining nuts or bolts.

Step 12: Turn On the Water Supply

Turn on the water supply and check for any leaks. If you notice any leaks, tighten the affected area or repeat the repair process.

Step 13: Clean Up

Clean up any tools or debris and dispose of them properly. Wipe down the sink and surrounding area to remove any excess water or debris.

Conclusion

Fixing a leaking sink is not as difficult as it may seem. By following these easy-to-follow steps, you can save yourself time and money by repairing the sink yourself. Remember to turn off the water supply before beginning any repairs and to check for any leaks once you have completed the repairs.
