How to Fix a Leaky Sink

Fixing That Annoying Leaky Sink: A DIY Guide

A leaky sink? Ugh, right? It's more than just annoying; it wastes water and could even cause expensive damage. But guess what? You can probably fix it yourself! This guide will show you how.

Finding the Leak: Where's the Drip Coming From?

Before you grab your tools, you need to find the source of the leak. This tells you how to fix it. Common culprits are:

• Worn-out faucet washers: This is super common, especially around the handles. You'll see drips when the faucet is off.
• Damaged O-rings or cartridges: These rubber bits create a watertight seal. If they're worn, you'll have leaks.
• Cracked faucet body: A crack or loose connection in the faucet itself can cause constant leaks.
• Leaks under the sink: These are often from loose connections on the pipes, a broken drain, or a problem with the P-trap (that curved pipe).
• Mineral buildup: Over time, mineral deposits can damage things, causing leaks. Think limescale buildup in your kettle.

Look carefully at the faucet and under the sink. Look for wet spots. Turn the faucet on and off, watching closely to see where the water is leaking.

What You'll Need: Gather Your Supplies

The exact tools depend on the problem, but here’s a good starting point:

• Adjustable wrench: For tightening and loosening nuts and bolts.
• Basin wrench: A special wrench for those hard-to-reach nuts under the sink.
• Screwdrivers (Phillips and flathead): For removing screws on the faucet handles.
• Pliers (needle-nose and channel-lock): For gripping small parts and tightening things.
• Putty knife: To remove old sealant.
• Caulk (silicone or plumber's putty): For sealing.
• Replacement parts (washers, O-rings, cartridges): Get these that match your faucet. Take a broken part to the hardware store if you're not sure.
• Bucket or towels: To catch spilled water.
• Safety glasses: Always protect your eyes!

Fixing Common Leaks: Let's Get This Done!

Scenario 1: Replacing Worn Washers

1. Turn off the water: Find the shut-off valves under the sink and turn them clockwise.
2. Remove the handles: Use a screwdriver to remove the screws holding the handles. Some handles might just pull off.
3. Remove the packing nut: This is under the handle. Use the adjustable wrench to carefully loosen it.
4. Remove the stem: This is the part that controls the water. Gently pull it out.
5. Replace the washer: Check the washer at the bottom. If it's bad, replace it with a new one.
6. Reassemble: Put everything back together, tightening things snugly.
7. Turn the water back on: Turn the valves counterclockwise. Check for leaks!

Scenario 2: Replacing O-rings or Cartridges

This is similar to replacing washers, but you'll take apart more. Check your faucet's instructions or look up a repair guide online for your specific faucet model. You might need to remove the whole cartridge or stem.

Scenario 3: Fixing Leaks Under the Sink

Leaks under the sink usually mean loose connections or broken parts. Check:

• Supply lines: Check for cracks or loose connections. Tighten anything loose with a wrench.
• P-trap: Check for loose connections or cracks. Tighten or replace if needed.
• Drain assembly: Check for loose or worn parts. Tighten or replace as needed.

Preventing Future Leaks: A Little Prevention Goes a Long Way

• Regular checks: Look for leaks often.
• Keep it clean: Clean the faucet and remove mineral deposits.
• Don't force it: Don't force the handles; you might break something.
• Fix small problems quickly: A small drip can become a big problem.

When to Call a Pro: Know Your Limits

Sometimes, you need a plumber. Call one if:

• You're not comfortable fixing it yourself.
• You can't find the leak.
• The leak is big or causing damage.
• You've tried and it's still leaking.
• You have an old or complicated plumbing system.

Fixing a leaky sink is satisfying! You'll save money and prevent bigger problems. Remember to turn off the water first! Good luck!
