How often should a septic tank be pumped? Is it better to pump a tank before an inspection or wait until after? We’ve researched for you; read on to learn when to empty your septic tank– and why it’s so important. 

Should a Septic Tank Be Pumped Before Inspection?

The short answer is no! While you must pump your tank regularly to maintain the system, you should wait to pump it too soon before inspection.

According to InspectAPedia, septic tank cleaning within two weeks before an inspection can result in inaccurate findings by the inspectors. Read on to discover the best time to pump your septic tank!

Why Not?

When considering whether to pump a septic tank before inspection, it’s important to recognize the potential impact on the assessment process. Pumping the tank shortly before testing can introduce complications that undermine the accuracy of the results. This action empties the septic tank, disrupting the loading and dye test’s ability to replicate real conditions. The loading and dye test involves introducing water and dye into the septic system to identify issues like backups or effluent breakouts onto the yard surface. By removing the tank’s contents through pumping, the test loses its ability to simulate the system’s typical functioning accurately. Consequently, the inspection might not accurately detect existing or impending septic system failures, potentially leading to undetected problems that could worsen over time.

How Often Should You Pump a Septic Tank?

Maintaining your household septic system is essential for efficiency and longevity. As per the United States Environmental Protection Agency, a septic service professional should inspect it at least every three years to catch and address issues promptly. Household septic tanks need regular pumping every three to five years, to prevent excess solids and ensure proper function.

Frequent yearly inspections are advisable for alternative septic systems with features like electrical float switches or pumps. These systems are more complex, requiring specialized care due to mechanized parts.

Several factors determine how often your septic system should be pumped. Household size impacts wastewater production, while total wastewater volume strains the system, demanding more maintenance for larger quantities. The concentration of solids affects efficiency, and septic tank size matters—smaller tanks need more frequent pumping to prevent overflow and ensure proper treatment.

Why Pump or Inspect a Septic Tank? 

A septic system is very important; it keeps the waste from your home out of the plumbing, allowing it to drain out as it should. The tanks need to be emptied to maintain the system and prevent issues such as waste backup or buildup so they continue to work well. 

In addition, there may be items in your tank that should be removed; for example, small children tend to flush things that aren’t septic-tank-friendly. Septic tank pumping allows for items of the like to be removed, along with excess waste!
