Plumbing is one of the most important systems in any home, yet it’s often overlooked until something goes wrong. From dripping faucets and clogged drains to burst pipes and water heater issues, plumbing problems can quickly turn into costly emergencies. The good news? With a little knowledge and regular maintenance, many common issues can be prevented—or at least caught early before they spiral out of control.
Whether you’re a new homeowner or someone who has lived in the same place for years, knowing a few essential plumbing tips can save you time, money, and stress. In this article, we’ll walk you through the top 10 plumbing tips every homeowner should know, plus some bonus advice to keep your system running smoothly for years to come.
1. Know Where Your Main Water Shut-Off Valve Is
One of the most important things every homeowner should know is the location of the main water shut-off valve. This valve controls the flow of water into your entire house.
-
Why it matters: If a pipe bursts or a major leak occurs, shutting off the water immediately can prevent severe flooding and water damage.
-
Where to find it: In most homes, the main shut-off valve is located in the basement, crawl space, utility area, or near the perimeter of your house.
-
Pro Tip: Test the valve periodically to ensure it turns easily. If it’s hard to turn, consider replacing it with a more user-friendly ball valve.
2. Don’t Ignore Small Leaks
That tiny drip from your faucet or small puddle under your sink may seem harmless, but it can cost you more than you think.
-
The hidden costs: Even a slow drip can waste gallons of water over time, increasing your water bill.
-
Potential damage: Moisture can lead to mold, mildew, and wood rot.
-
Fix it early: Most small leaks are caused by worn-out washers or loose fittings and can often be fixed with basic tools.
Remember: ignoring a small leak can turn into a much bigger—and more expensive—repair later.
3. Avoid Chemical Drain Cleaners
Clogged drains are one of the most common plumbing problems, but reaching for a chemical drain cleaner isn’t always the best solution.
-
The risks: Chemical cleaners are harsh and can corrode your pipes over time. They’re also harmful to the environment.
-
Better alternatives:
-
Use a plunger for sinks or toilets.
-
Try a drain snake/auger to physically remove clogs.
-
Prevent clogs by using drain strainers to catch hair, food, and debris.
-
If clogs keep happening, it could be a sign of a bigger issue in your plumbing system—so it’s best to call a professional.
4. Learn How to Handle Running Toilets
A toilet that won’t stop running is more than just an annoyance—it wastes a surprising amount of water.
-
Common causes:
-
Worn-out flapper valve
-
Improperly adjusted float
-
Faulty fill valve
-
-
DIY fix: Replace the flapper or adjust the float mechanism inside the tank. These are inexpensive parts you can pick up at any hardware store.
-
Why act quickly: A running toilet can waste hundreds of gallons of water per day, which significantly increases your water bill.
5. Insulate Your Pipes in Cold Weather
If you live in a colder climate, frozen pipes can be a nightmare. When water freezes inside a pipe, it expands, which can cause the pipe to burst.
-
Prevention tips:
-
Wrap exposed pipes with foam insulation sleeves.
-
Use heat tape for added protection in very cold areas.
-
Keep cabinet doors open during cold spells to allow warm air to circulate around pipes.
-
-
Emergency tip: If your pipes freeze, shut off the water immediately and gently thaw them with a hairdryer. Never use an open flame.
Insulating pipes is inexpensive and can save you from thousands of dollars in repairs.
6. Don’t Overload Your Garbage Disposal
Garbage disposals are convenient, but they’re not designed to handle everything. Misusing them can lead to clogs, jams, or broken blades.
-
What NOT to put down the disposal:
-
Grease, fats, and oils
-
Fibrous foods (celery, corn husks, onion skins)
-
Bones, pits, or shells
-
Coffee grounds and eggshells (they build up in pipes)
-
-
Pro Tip: Always run cold water before, during, and after using your disposal to flush debris down the pipes.
Treat your garbage disposal with care, and it will last much longer.
7. Know the Signs of Hidden Leaks
Not all plumbing problems are obvious. Some leaks hide behind walls or under floors, quietly causing damage.
-
Signs to watch for:
-
Unexpectedly high water bills
-
Water stains on ceilings or walls
-
Mold or mildew smells
-
Low water pressure
-
-
How to check: Turn off all faucets and appliances, then check your water meter. If it’s still moving, you may have a leak.
Catching hidden leaks early can save your home from serious structural damage.
8. Take Care of Your Water Heater
Your water heater works hard every day, but it often gets neglected until it stops working. Regular maintenance extends its life and efficiency.
-
Tips for water heater care:
-
Drain and flush the tank once a year to remove sediment buildup.
-
Check the temperature setting (120°F is recommended for efficiency and safety).
-
Inspect the anode rod every 2–3 years and replace it if it’s corroded.
-
-
Signs it’s time to replace: Rusty water, strange noises, or water that never gets hot enough.
With proper care, a water heater can last 8–12 years or longer.
9. Respect Your Septic System (If You Have One)
If your home uses a septic system instead of city sewer, it requires special attention.
-
Best practices:
-
Don’t flush anything except toilet paper and human waste.
-
Avoid pouring grease or chemicals down drains.
-
Schedule professional pumping every 3–5 years.
-
-
Warning signs: Pooling water in the yard, slow drains, or bad odors may mean your system needs service.
Taking care of your septic system saves you from costly repairs or replacements.
10. Build a Relationship with a Trusted Plumber
Even the most prepared homeowners can’t fix everything. Having a trusted plumber on speed dial is one of the smartest things you can do.
-
Why it matters:
-
Emergencies happen at odd hours, and a reliable plumber can save the day.
-
Regular inspections can prevent issues before they start.
-
Good plumbers offer advice tailored to your specific home and plumbing system.
-
Don’t wait until disaster strikes to look for a plumber—research and establish a connection now.
Bonus Plumbing Tips
-
Install water-saving fixtures: Low-flow showerheads and faucets save money and water.
-
Keep an eye on water pressure: Too much pressure can damage pipes and appliances.
-
Use your senses: Listen for gurgling drains, smell for foul odors, and look for water stains—all signs of trouble.
-
Have basic tools on hand: A plunger, pipe wrench, and plumber’s tape can solve many minor issues.
