Top 10 Plumbing Problems in Homes: How to Fix Them (And When to Call a Pro)

Plumbing problems are every homeowner’s nightmare. Whether it's a dripping faucet or a backed-up sewer line, these issues can lead to expensive repairs if ignored. The good news? Many common plumbing problems can be fixed with a little know-how and the right tools. But there are also times when it's best to leave it to the professionals.

In this blog, we’ll cover the top 10 most common plumbing problems in homes, how you can fix them yourself, and the red flags that mean it's time to call in a licensed plumber.

1. Leaky Faucets

The Problem:

That constant “drip…drip…drip” doesn’t just annoy you—it wastes hundreds of gallons of water every year.

DIY Fix:

·         Turn off the water supply.

·         Remove the faucet handle and replace the washer or O-ring.

·         Reassemble and test.

Call a Pro If:

·         The leak persists after replacing washers.

·         Corrosion or structural damage is found inside the faucet.

2. Clogged Drains

The Problem:

Slow-draining sinks or showers are usually caused by hair, soap scum, or grease buildup.

DIY Fix:

·         Pour boiling water down the drain.

·         Use a plunger or a drain snake.

·         Try a baking soda and vinegar solution.

Call a Pro If:

·         Multiple drains are clogged at once (a sign of a main line blockage).

·         There’s a foul odor or gurgling noise.

3. Running Toilets

The Problem:

A toilet that keeps running wastes up to 200 gallons of water a day!

DIY Fix:

·         Open the tank and check the flapper—it may need to be replaced.

·         Adjust the float to stop water from rising too high.

·         Check for a loose fill valve.

Call a Pro If:

·         You’ve replaced the flapper and adjusted the float but it’s still running.

·         You suspect a hidden leak between the tank and bowl.

4. Low Water Pressure

The Problem:

Weak water flow can make showers and sink use frustrating.

DIY Fix:

·         Clean faucet aerators and showerheads (mineral buildup is a common cause).

·         Check for closed shut-off valves.

Call a Pro If:

·         The issue is affecting the entire house.

·         You suspect a leak in the supply line or corroded pipes.

5. Dripping or Leaky Pipes

The Problem:

Leaky pipes can cause water damage, mold, and higher utility bills.

DIY Fix:

·         Use pipe clamps or epoxy putty for temporary fixes.

·         Insulate pipes to prevent freezing in winter.

Call a Pro If:

·         Leaks are recurring or in hard-to-access areas.

·         There’s visible water damage or mold.

6. Water Heater Issues

The Problem:

No hot water? Discolored water? Your water heater may be to blame.

DIY Fix:

·         Check the pilot light (for gas heaters) or breaker (for electric heaters).

·         Flush the tank to remove sediment buildup.

Call a Pro If:

·         The water smells like rotten eggs or is rusty.

·         The tank is leaking or over 10 years old.

7. Clogged Toilets

The Problem:

Toilet clogs are usually caused by excessive toilet paper or non-flushable items.

DIY Fix:

·         Use a flange plunger to create a strong seal and push the blockage through.

·         Try a toilet auger for stubborn clogs.

Call a Pro If:

·         The toilet overflows repeatedly.

·         Other drains are backing up, suggesting a deeper blockage.

8. Sewer System Backup

The Problem:

This is one of the most serious plumbing issues—a sewer backup can flood your home with hazardous waste.

Warning Signs:

·         Multiple drain clogs.

·         Bad sewage smells.

·         Water backing up from floor drains.

DIY Fix:

Don’t attempt DIY for sewer backups—this is a job for professionals only.

Call a Pro Immediately:

·         If you notice sewage backup or suspect tree root intrusion.

·         If water backs up when using appliances or fixtures.

9. Burst Pipes

The Problem:

Usually caused by freezing temperatures, burst pipes can flood your home in minutes.

Immediate DIY Action:

·         Shut off your main water supply.

·         Drain faucets to reduce pressure.

Call a Pro If:

·         Any pipe has burst or cracked.

·         You notice water spots on walls, ceilings, or floors.

10. Noisy Pipes

The Problem:

Rattling or banging pipes (also known as “water hammer”) can indicate unsecured lines or high water pressure.

DIY Fix:

·         Secure loose pipes with brackets or insulation.

·         Install a water hammer arrestor.

Call a Pro If:

·         The noise persists after securing pipes.

·         You suspect high water pressure or valve issues.

Bonus Tips: Preventative Maintenance for a Healthier Plumbing System

Prevention is better than cure. Here are some quick maintenance tips to avoid these common problems:

·         Install drain screens to catch hair and debris.

·         Avoid pouring grease down the kitchen sink.

·         Flush your water heater annually to remove sediment.

·         Check for leaks monthly—look under sinks and behind toilets.

·         Insulate exposed pipes before winter to avoid freezing.

·         Schedule an annual plumbing inspection to catch issues early.
