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:

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.
