Understanding the Common Causes of a Leaky Faucet

Before you start repairs, it is important to understand what causes faucet leaks. The most common issues include:

  • Worn-Out Washers or O-Rings
  • Corroded Valve Seats
  • Damaged Cartridges or Ceramic Disks
  • Loose Faucet Components

Identifying the correct cause saves time and ensures a lasting fix.

How to Fix a Leaky Faucet: Step-by-Step Guide

1. Shut Off the Water Supply

Locate the water supply valves under the sink and turn them off completely. Open the faucet to release any remaining water.

2. Identify Your Faucet Type

Check whether you have a:

  • Compression Faucet
  • Ball Faucet
  • Cartridge Faucet
  • Ceramic Disk Faucet

Each type has a slightly different repair method. Knowing this helps you get the right parts.

3. Disassemble the Faucet

  • Use an adjustable wrench or screwdriver to remove the handle.
  • Take off the decorative cap if there is one.
  • Unscrew and remove internal components carefully, noting their order.

4. Inspect and Replace Worn Parts

  • Check Washers, O-Rings, and Seals for wear, cracks, or hardening.
  • Look at Cartridges or Ball Assemblies for signs of damage.
  • Clean Valve Seats with white vinegar to remove mineral buildup.

Always replace worn parts with exact matches. Sparrow Supply offers Faucet Repair Kits to simplify the process.

5. Reassemble and Test

  • Reassemble the faucet carefully in reverse order.
  • Turn the water supply back on slowly.
  • Test the faucet for leaks by running both hot and cold water.

If leaks persist, double-check the installation or consider replacing the entire cartridge or valve seat.
