How to Fix a Dripping Faucet: A Simple Step-by-Step Guide

A dripping faucet is more than just an annoying sound; it is a waste of water and money. Whether it’s a steady stream or a slow drip, learning how to fix a dripping faucet is a vital DIY skill that can save you a significant amount on your monthly water bill.

In most cases, you don’t need a plumber. Most leaks are caused by a worn-out washer, O-ring, or cartridge. Here is how you can fix it yourself in four easy stages.

1. Prepare Your Tools and Turn Off the Water

Before you begin, gather the following tools:

  • An adjustable wrench
  • Phillips and flat-head screwdrivers
  • Replacement washers and O-rings (or a new cartridge)
  • Plumber’s grease (optional)

Crucial Step: Turn off the water supply. Look under the sink for the shut-off valves and turn them clockwise. Then, turn on the faucet to drain any remaining water in the pipes.

2. Disassemble the Faucet Handles

To get to the source of the leak, you must take the faucet apart:

  • Remove the decorative caps on the handles (usually labeled “H” or “C”).
  • Unscrew the handle screw and pull the handle off.
  • Use your wrench to unscrew the packing nut, revealing the stem or the cartridge.

3. Identify and Replace the Damaged Part

Once the faucet is disassembled, inspect the internal components:

  • Compression Faucets: These usually have a rubber washer that gets worn down. Replace the old washer with a new one of the exact same size.
  • Cartridge Faucets: If you have a single-handle faucet, you likely have a cartridge. It is often easier to simply pull the old cartridge out and insert a new one from the hardware store.
  • O-Rings: If the leak is coming from the base of the handle, the O-ring is likely the culprit. Replace it and apply a little plumber’s grease for a better seal.

4. Reassemble and Test

Put the parts back together in the reverse order you took them out. Tighten the packing nut, replace the handle, and screw the decorative cap back on.

Slowly turn the water supply back on and check for any leaks. Your faucet should now be silent and dry!

Conclusion

Knowing how to fix a dripping faucet not only preserves your home’s plumbing but also contributes to environmental conservation. If the leak persists after replacing the parts, it may be time to replace the entire fixture or call a professional.
