Chart: How Often Should a Septic Tank Be Pumped Out?

Septic Tank Maintenance

Out of sight, out of mind. Pumping your septic tank is one of the easiest home maintenance tasks to forget about – the tanks are buried, and the access port is usually covered in dirt and hard to access. However, this important maintenance task will help you avoid smelly and expensive septic tank or drain field repairs. If they are regularly pumped, septic tanks can last decades and provide reliable sewage treatment.

How Often Should a Septic Tank Be Pumped Out?

That’s a great question, and the answer depends on several variables. The size of your family, tank size, whether or not you have a garbage disposal, and climate are a few factors that will influence the service interval. Use the chart below to find out the how often you should pump your septic tank.

How Do I Know My Septic Tank is Full?

Hopefully you’re suspicious of a full septic tank before your yard is flooded with sewage. If you notice the drains in your home backing up, this is a good indicator the septic tank needs to be pumped. Foul odors, sewage smells or standing water outside your home can also indicate septic tank failure. Clogged pipes or sewer blockages can sometimes seem like septic tanks problems, so it’s best to get a professional diagnosis. If none of these symptoms is present, locate your septic tank access port. Put on gloves, protective clothing and eyewear for safety, and then insert a 6’ – 10’ wooden rod vertically into the septic tank. If the sludge is more than one-third full, it’s time for a pump.
