Leaky faucets are one of the most common household plumbing issues, and knowing how to fix a leaky faucet can save you money and prevent water waste. In fact, according to the U.S. Environmental Protection Agency, household leaks can waste nearly 1 trillion gallons of water annually in the United States alone (EPA). In this guide, we’ll walk you through how to fix a leaky faucet, when to tackle the repair yourself, and when it’s best to call a professional plumber like Beis Plumbing in St. Louis.
Why Is My Faucet Leaking?
Understanding the cause is the first step in learning how to fix a leaky faucet. Common reasons include:
- Worn-out washers or gaskets
- Corroded valve seats
- Loose or broken parts
- High water pressure
Ignoring a leaky faucet can lead to higher water bills and even water damage over time.
Tools and Materials You’ll Need
Before you start, gather these supplies:
- Adjustable wrench
- Screwdriver (flathead and Phillips)
- Replacement washers or O-rings
- Plumber’s grease
- Cloth or towel
Step-by-Step: How to Fix a Leaky Faucet
1. Turn Off the Water Supply
Locate the shutoff valves under the sink and turn them clockwise to stop the water flow. Open the faucet to drain any remaining water.
2. Remove the Faucet Handle
Use a screwdriver to remove the handle. Some handles have decorative caps that need to be pried off first.
3. Take Apart the Faucet
Carefully unscrew the packing nut with an adjustable wrench. Remove the stem or cartridge, depending on your faucet type.
4. Inspect and Replace Parts
Check washers, O-rings, and seals for wear. Replace any damaged parts. This is a crucial step in how to fix a leaky faucet.
5. Reassemble and Test
Reassemble the faucet in reverse order. Turn the water supply back on and check for leaks.
When Should You Call a Plumber?
While many homeowners can handle minor leaks, there are times when calling a professional is the best option:
- The leak persists after replacing washers and O-rings
- You notice water pooling under the sink or signs of water damage
