Out of sight, out of mind—until there’s a problem. Your septic tank is one of those systems you rarely think about… unless it starts acting up. And trust us, when it does, it’s not subtle. The good news? With just a little bit of care (and some things to steer clear of), you can keep your septic system running smoothly for years.
Here are two key ways to take care of it—and two things you should definitely avoid.
DO: Pump Your Tank Regularly
Think of this like a routine check-up for your home’s underground plumbing. Over time, solids build up in your septic tank, and if they’re not removed, they can clog the drain field and cause serious (and expensive) damage.
How often? Typically, every 3–5 years, depending on household size and water usage. A professional can help you determine the right schedule for your home.
DO: Watch What Goes Down the Drain
Your septic system isn’t built to handle everything. Being mindful of what you flush or pour down the drain is one of the simplest—and most effective—ways to protect it.
Stick to septic-safe toilet paper and avoid putting grease, coffee grounds, medications, and harsh chemicals down the sink or toilet. They can kill off the helpful bacteria in your tank that break down waste and keep everything flowing properly.
DON’T: Use Additives Without Doing Research
There are tons of septic additives on the market promising to “extend the life of your tank” or “eliminate the need to pump.” While it sounds tempting, many of these products are unnecessary—or worse, harmful.
Some additives can disrupt the natural bacterial balance or push solids into your drain field prematurely. If you’re considering one, consult a septic professional first.
DON’T: Park or Build on Top of the System
Your septic tank and drain field need breathing room—literally. Parking heavy vehicles or building structures (like decks, sheds, or patios) over them can compress the soil and damage pipes, leading to backups or total system failure.
Stick to planting grass over your system and keep heavy traffic out of the area.
Final Thought
Your septic system might be underground, but it shouldn’t be overlooked. With just a couple of smart habits—and by avoiding some common missteps—you can keep things running smoothly and prevent costly repairs down the road. A little care goes a long way when it comes to what’s beneath your backyard.
