Identifying the Cause of the Leak

The first step in fixing a leaky faucet is to determine the source of the leak. Here are the most common culprits:

1. Worn-out Washer: This is the most frequent cause of leaks in older faucets. The washer is a small rubber or plastic disc that seals the water flow. Over time, the washer can wear down, crack, or become brittle, allowing water to escape.
2. Damaged O-ring: O-rings are small rubber seals that prevent water from leaking around the stem or cartridge of the faucet. If the O-ring is damaged, cracked, or missing, water will leak past it.
3. Loose or Worn-out Cartridge: Some faucets use a cartridge, which is a single unit containing the valve and washer. If the cartridge is loose, worn, or damaged, water will leak through the valve.
4. Corrosion: Corrosion can occur in the faucet's internal components, causing leaks. The corrosion can be due to hard water, mineral deposits, or other factors.
5. Loose or Broken Valve Stem: The valve stem is the part that controls the flow of water. If the valve stem is loose or broken, water can leak past it.

Gathering Your Tools and Materials

Once you know the cause of the leak, you can gather the necessary tools and materials. Here's a list of essentials:

• Adjustable Wrench: Used for tightening and loosening nuts and bolts.
• Channel-Lock Pliers: Useful for gripping and turning irregular or oddly shaped parts.
• Phillips Screwdriver: For removing screws on faucet handles and covers.
• Flat-Head Screwdriver: For removing screws and making adjustments.
• Replacement Washer: Choose a washer compatible with your faucet type.
• Replacement O-ring: Select an O-ring that matches the size and material of the existing one.
• Replacement Cartridge (if needed): If you need to replace the cartridge, ensure it's the correct model for your faucet.
• Teflon Tape (optional): Used to seal threads and prevent leaks.
• Work Gloves: Protect your hands from sharp edges and water.
