Septic tanks are an essential component of many Canadian homes, especially in rural areas. 

However, these systems often come with a fair share of myths and misconceptions. These misunderstandings can lead to improper care and maintenance, which may result in costly issues down the line. 

In this article, we aim to debunk common septic tank myths and provide accurate information to help homeowners in Canada better understand the importance of septic tank maintenance.

 Septic Tank Myths

Myth 1: Septic Tanks Last Forever

Fact: Septic tanks have a lifespan, typically ranging from 25 to 40 years, depending on various factors like usage, maintenance, and the quality of the tank. Regular maintenance is crucial to extend the tank’s life.

Myth 2: Additives Keep Septic Tanks Healthy

Fact: While some products claim to enhance septic tank performance, most septic systems do not require additives. In fact, certain chemicals can disrupt the natural bacterial balance within the tank, potentially leading to issues.

Myth 3: It’s Safe to Flush Anything

Fact: Flushing non-biodegradable items like diapers, sanitary products, and wipes can clog your septic system. Only human waste and toilet paper should be flushed.

Fact: Routine septic tank pumping is essential for preventing problems. The frequency depends on factors like tank size and household usage, but it’s typically recommended every 3-5 years.

Fact: Regular inspections by a professional are crucial for detecting issues early. Inspections can uncover problems like leaks, blockages, and structural damage before they become major concerns.

Myth 7: A Well-Maintained Septic Tank Won’t Smell

Fact: Even with proper maintenance, septic tanks may produce odours from time to time. If there’s a persistent foul smell, it could be a sign of a problem that needs attention.

Fact: Harsh chemical cleaners can kill the beneficial bacteria in the septic tank, disrupting its function. Using septic-safe cleaning products is advisable.
