If there’s one thing that can quietly ruin your day (and your drywall), it’s a plumbing issue. Whether it’s a slow drain or a surprise leak, plumbing is one of those behind-the-scenes systems we tend to ignore — until it stops working.
But the good news? With a few simple maintenance habits, you can prevent most common plumbing problems before they start.
Here are seven expert-backed tips that every homeowner should keep in their back pocket.
1. Know Where Your Main Shut-Off Valve Is
If a pipe bursts or a fixture overflows, the first thing you need to do is stop the water. That means knowing exactly where your main shut-off valve is — and making sure it’s accessible and functional. Trust us: the time to find it is not while your kitchen is turning into a swimming pool.
Make it a point to test the valve once or twice a year. Older valves can seize up or corrode, especially in humid environments or if they haven’t been touched in years. Being proactive could save thousands in water damage.
2. Don’t Ignore Slow Drains
A slow drain isn’t just annoying — it’s often a sign of a partial blockage. And those don’t fix themselves. Use a drain snake or eco-friendly cleaner to remove buildup before it becomes a full-on clog. Avoid chemical drain openers, as they can damage your pipes over time.
Pay special attention to bathroom sinks and tubs — hair and soap residue are common culprits. Installing a simple drain screen can go a long way in preventing buildup.
3. Test Water Pressure Regularly
Low water pressure can be a symptom of a leak, sediment buildup, or even a broken pipe. High pressure can damage fixtures and pipes. A simple $10 gauge from the hardware store can help you monitor your pressure and keep it in the sweet spot (usually 40–60 psi).
If you consistently get high readings, consider installing a pressure-reducing valve (PRV). It’s a relatively small investment that protects your entire plumbing system over time.
4. Flush Your Water Heater (Once a Year, Please)
Over time, sediment builds up in your water heater, reducing its efficiency and lifespan. Draining a few gallons once a year can flush out that buildup. It’s a quick maintenance task that can save you hundreds on premature replacements.
Homeowners with hard water may want to flush the tank twice a year or consider installing a whole-house water softener to reduce mineral buildup.
5. Know What Not to Flush
Your toilet isn’t a trash can. The only things that should go down it: human waste and toilet paper. “Flushable” wipes, paper towels, feminine products, cotton balls — they don’t break down like TP and can cause major backups.
According to Super Brothers, a plumbing company based in Sacramento, California, one of the most common emergency calls they get is due to improper disposal in toilets — and it’s often an expensive fix.
Even when labels claim something is “flushable,” remember: just because it goes down doesn’t mean it won’t get stuck.
6. Fix Leaks Promptly
That slow drip in your bathroom sink might seem harmless, but over time it wastes water and wears down fixtures. Even minor leaks can signal pressure problems or deteriorating seals. Don’t put them off.
Leaks also promote mold and mildew, which can affect indoor air quality and cause health issues. If you spot water stains on ceilings or walls, act immediately — even if the source isn’t obvious.
7. Schedule Routine Inspections
Even if nothing seems wrong, a professional inspection every few years can catch hidden problems before they become disasters. Cracked pipes, corroded fittings, and failing shut-off valves are all issues that can lurk unseen — until it’s too late.
Licensed local plumbing services offer inspections that include pressure testing, pipe camera scans, and water quality checks. It’s a small investment for major peace of mind.
Many plumbers also offer maintenance plans that include annual checkups, priority scheduling, and discounts on emergency repairs — something worth considering if your home is over 20 years old.
Bonus Tip: Winterize Outdoor Plumbing
If you live in a region where temperatures drop below freezing, don’t forget to shut off and drain outdoor faucets before winter. Burst pipes caused by frozen water can result in major damage — and they’re almost entirely preventable.
Install frost-free hose bibs and insulating covers for extra protection. If you have irrigation systems, blow them out before the first freeze.
Final Thoughts
Your home’s plumbing doesn’t need constant attention — but it does need some. Like oil changes for your car, regular maintenance goes a long way toward avoiding breakdowns.
And while a handy homeowner can tackle plenty of basic tasks, don’t hesitate to call in the pros for anything beyond the basics. Because nothing ruins a Saturday faster than realizing you’re ankle-deep in something you thought you fixed.
A little attention now prevents a lot of stress later.
