The Do’s and Don’ts of Septic System Care

Estimated reading time: 5 minutes

Septic maintenance isn’t the most exciting home task, but ignoring it? That’s a recipe for disaster. A backed-up toilet, strange odors, or a soggy yard are all signs I’ve waited too long to take care of things.

The good news? It doesn’t take much effort to keep everything running smoothly. I just need to follow a few simple do’s and don’ts to prevent costly repairs and headaches.

Here’s what I’ll cover:

  • Essential maintenance steps
  • Common mistakes that can cause major issues
  • Warning signs that I shouldn’t ignore
  • Best practices to extend the lifespan of my setup

By following these tips, I can avoid messy problems and keep my home’s wastewater treatment working efficiently.

The Do’s of Septic Care

A little attention now can save me from expensive problems later. Here’s how I keep everything working as it should.

Schedule Regular Pumping

  • I arrange professional pumping every three to five years to remove solid buildup.
  • Larger households or homes with frequent water use may need more frequent service.
  • Avoiding this leads to overflow, and that’s not something I ever want to deal with.

Use Water Wisely

  • Running multiple appliances at once—like the washing machine and dishwasher—puts stress on the system.
  • Fixing leaks prevents unnecessary water flow into the tank.
  • The less liquid waste I send in, the longer my setup lasts.

Choose Septic-Safe Products

  • Flushing the wrong items is a surefire way to cause blockages. I stick to biodegradable toilet paper and avoid anything labeled “ultra-thick.”
  • Harsh chemicals can kill the bacteria that break down waste, so I use mild, septic-friendly cleaners.
  • Pouring grease down the drain is a bad habit—it solidifies and clogs pipes.

Protect the Drainage Area

  • I keep the area clear of trees and deep-rooted plants—roots love to invade underground pipes.
  • Parking cars or placing heavy structures over the soil can compress the system and cause damage.
  • Redirecting rainwater helps prevent oversaturation, which could cause pooling or backups.

Schedule Inspections

  • Having a professional check for leaks and wear helps catch small issues before they become big problems.
  • I keep records of all maintenance, so I always know when the next service is due.

The Don’ts of Septic Care

The Don’ts of Septic Care

Neglecting small details can lead to major headaches. Here’s what I avoid.

Flushing the Wrong Items

  • My toilet isn’t a trash can. I never flush:
    • Wipes (even the ones labeled “flushable”)
    • Feminine hygiene products
    • Paper towels
    • Diapers
    • Dental floss or cotton swabs
  • If it’s not waste or toilet paper, it belongs in the trash.

Overloading the System

  • Using too much water at once floods the tank and reduces efficiency.
  • Running multiple water-heavy appliances at the same time should be avoided.
  • Installing low-flow toilets and efficient showerheads helps reduce excess water use.

Using Harsh Chemicals

  • Bleach, antibacterial soaps, and drain cleaners can kill the good bacteria needed for proper breakdown.
  • Instead, I use natural alternatives like vinegar and baking soda for cleaning.

Ignoring Warning Signs

  • If drains are slow, there’s a foul odor, or water starts pooling outside, I know it’s time to take action.
  • Waiting too long could mean needing major repairs.

Trusting Quick Fixes Over Routine Maintenance

  • Septic additives promise to break down solids, but they don’t replace professional pumping.
  • Ignoring inspections and relying on store-bought solutions can lead to major clogs and system failure.

If I notice slow drainage or odors, I check for these warning signs to see if immediate attention is needed.

Common Mistakes That Lead to Costly Repairs

Even with good intentions, I could be making small mistakes that result in expensive problems. Here are a few things I avoid:

  • Letting tree roots grow too close – Root damage is one of the biggest causes of underground pipe failure.
  • Skipping regular maintenance – Waiting until there’s a problem usually means a much bigger (and costlier) fix.
  • Ignoring slow-draining sinks and toilets – These are early warning signs of a clog forming.

For homeowners who also want to avoid foundation-related issues, I suggest reviewing these warning signs to keep the entire property in good condition.

Signs I Need Professional Help

Some issues can’t be ignored. If I notice any of these, I call an expert:

  • Drains that are constantly slow, even after using a plunger
  • Gurgling sounds coming from pipes
  • A strong sewage smell outside or inside my home
  • Puddles of water near the drainage area
  • Wastewater backing up into sinks, tubs, or toilets

How to Keep Everything Running Smoothly for Years

Septic maintenance doesn’t have to be complicated. These habits help extend the system’s lifespan:

  • Monitor water use – The less unnecessary water I send in, the better.
  • Schedule maintenance before there’s a problem – Preventative care is much cheaper than repairs.
  • Keep landscaping in check – Trees, shrubs, and heavy objects stay far away from the drainage area.
  • Make sure everyone in my household knows the rules – Flushing the wrong things affects the whole system.

For homeowners managing other drainage concerns, I also recommend reading about gutter maintenance to prevent water damage near the home’s foundation.

Final Thoughts

A little attention goes a long way in avoiding septic disasters. By following the right habits, I can prevent backups, protect my property, and save money on costly repairs.

If I had to give just one piece of advice, it would be this: Regular maintenance keeps everything running smoothly—don’t wait for a problem to act.
