Understanding Your Septic System: Common Myths Debunked

For homeowners across Ajax, Oshawa, Whitby, and the surrounding communities, a septic system is often an essential component of efficient home plumbing. At Call the Plumbing Doctor, we know first-hand how misconceptions can lead to costly repairs or environmental issues. Whether you’re new to septic systems or a seasoned homeowner, it’s crucial to separate fact from fiction. Let’s debunk some of the most common septic system myths and provide practical, locally relevant advice to keep your system working flawlessly.


What is a Septic System and Why Does It Matter?


A septic system is an underground wastewater treatment structure found in homes not connected to municipal sewer lines. It safely processes household wastewater, ensuring safe disposal without harming the local environment in communities like Bowmanville, Clarington, and Pickering. Proper septic system maintenance is vital for protecting your property value and avoiding health hazards.


Myth 1: Septic Systems Don’t Need Regular Maintenance


Many believe that once a septic system is installed, it’s maintenance-free. In reality, regular inspections and pump-outs are essential for efficient performance and longevity.


Why regular septic system maintenance matters:


  • Prevents expensive system failures and backups.
  • Protects family health by avoiding hazardous waste leaks.
  • Ensures compliance with local health and safety regulations in Durham Region and beyond.


Septic systems in Ajax, Uxbridge, and Port Perry should be inspected at least every three years and pumped every 3-5 years, depending on household size and water usage.


Myth 2: Additives Eliminate the Need for Pumping


Some products claim to “clean” your septic system or extend pumping intervals, but these additives rarely replace proper maintenance. In fact, some may disrupt the natural bacterial balance necessary for wastewater breakdown.


Tips for healthy septic systems:


  • Stick to professional inspections and scheduled pump-outs.
  • Avoid flushing chemicals or non-biodegradable items.
  • Use water efficiently to reduce system strain.


Myth 3: All Plumbing Issues Are Unrelated to Your Septic System


It’s easy to blame a slow drain or unpleasant odor on minor clogs, but your septic system might be the culprit. Ignoring these early warning signs can lead to significant, costly repairs down the road.


Common signs your septic system needs attention:


  • Gurgling sounds or slow drains in plumbing fixtures.
  • Wet spots or lush grass over the drain field.
  • Sewage odors inside or outside the home.


If you notice any of these indicators, Call the Plumbing Doctor can assess your system and recommend necessary repairs or maintenance.


Myth 4: It’s Fine to Park or Build Over a Septic System


In fast-growing areas like Courtice or Brooklyn, property owners sometimes overlook the importance of septic system protection. Parking vehicles or constructing sheds over the septic tank or drain field can cause damage and system failure.


Protect your septic system by:


  • Keeping vehicles and heavy machinery away from the tank and drain field.
  • Avoiding planting trees with deep roots nearby.
  • Marking the location of your tank and drain field for easy access.


Myth 5: Septic Systems Always Need Complete Replacement if Problems Arise


Not every issue means you’re due for a new system. Many septic repairs—such as tank pumping, pipe clearing, or field rejuvenation—can restore performance without full replacement. Trusting experienced local plumbers in Clarington, Blackstock, and surrounding areas ensures your septic problems are properly diagnosed.
