Plumbing issues are some of the most common—and most frustrating—problems homeowners face. A small leak or slow drain may seem harmless at first, but ignoring early signs can lead to costly repairs, water damage, mold growth, and structural issues. Whether you’re dealing with a clogged drain, dripping faucet, or a major pipe burst, knowing what to look for can save you time and money.

In this guide, we break down the 10 most common plumbing problems and the best ways to fix them, as well as when it’s time to call a professional plumber.

1. Leaky Faucets

A dripping faucet can waste more than 3,000 gallons of water per year. Most leaky faucets are caused by:

• Worn-out O-rings
• Damaged cartridges
• Loose parts

Fix: Replacing the worn components usually solves the issue. If your faucet is older than 10 years, consider a full replacement to avoid recurring problems.

2. Slow or Clogged Drains

Food debris, grease, soap scum, hair, and mineral buildup are the most common culprits.

Fix:

• Use a drain snake to remove blockages
• Avoid chemical drain cleaners—they damage pipes
• Install drain screens to prevent future clogs

SEO Tip: Homeowners often search “drain cleaning near me,” so include this keyword if your website represents a plumbing company.

3. Running Toilets

A running toilet can waste hundreds of gallons per day. Common causes include:

• Faulty flappers

• Improper float level

Fix: Replace the flapper or flush valve assembly. These parts are inexpensive and easy to install.

4. Low Water Pressure

If water trickles instead of flowing, you might have:

• Mineral buildup in aerators
• Pipe corrosion
• Hidden leaks
• Water supply issues

Fix:
Clean faucet aerators or showerheads with vinegar. If pressure is low throughout the home, call a plumber to check for leaks or damaged piping.

5. Leaking Pipes

Pipe leaks can lead to mold, foundation damage, and high water bills. Common causes include:

• Rust
• Frozen pipes
• High water pressure
• Pipe joint failures

Fix:
Temporary fixes include pipe tape or clamps, but you should call a plumber for a permanent solution, especially if the leak is inside a wall or ceiling.

6. Water Heater Problems

Signs your water heater needs attention:

• No hot water
• Strange noises
• Rust-colored water
• Water pooling around the heater

Fix:
Flush your water heater annually to remove sediment. If it’s more than 10–12 years old, replacement is often the best option.

7. Sump Pump Failure

Basement flooding often occurs because of:

• Power outages
• Clogged intake
• Old or failing pumps

Fix:
Test your sump pump regularly and replace it every 7–10 years.

8. Burst Pipes

This is one of the most serious plumbing emergencies, especially during winter.

Fix:
Shut off your water immediately and call an emergency plumber. A burst pipe can cause thousands of dollars in damage if not handled quickly.

9. Sewer Line Backup

Warning signs include:

• Multiple drains clogging at once
• Gurgling sounds
• Sewage odors
• Water backing up into tubs or toilets

Fix:
A camera inspection can identify root intrusions, collapsed pipes, or blockages. Sewer repair or replacement may be required.

10. Dripping Water Hose Bibb

Outdoor spigots often leak after winter due to frozen pipes.

Fix:
Install frost-free hose bibbs to prevent future damage.
