How Often Should You Pump Your Septic Tank?

One of the most common questions homeowners ask is: “How often should I pump my septic tank?” While the general guideline is every 3 to 5 years, the truth is that the right pumping schedule depends on a variety of factors—like your tank size, household size, water usage, and how well you care for your system.

If you’re a homeowner in Livingston County, MI and want to avoid backups, costly repairs, or system failure, this guide will help you determine the best schedule for your septic tank.

At Anything Outdoors Septic and Excavating, we provide affordable septic tank pumping starting at just $325 for 1,000-gallon tanks and $400 for 1,500-gallon tanks. Let’s break down what you need to know.

Key Factors That Affect Septic Tank Pumping Frequency

Every septic system is unique, but these are the main factors that determine how often you should pump your tank:

1. Tank Size

Larger septic tanks can store more wastewater and solids, which means they don’t need to be pumped as frequently. Smaller tanks fill up much faster.

2. Household Size

The number of people living in your home directly impacts your septic system. More people = more water usage = faster tank fill-up.

3. Water Usage Habits

Do you take long showers, do laundry daily, or use your dishwasher frequently? High water use speeds up the need for pumping.

4. What You Flush & Drain

Grease, food scraps, chemicals, and so-called “flushable” wipes all shorten the lifespan of your system. The more careful you are, the longer you can go between pump-outs.
