How often should I pump my septic tank?

There is no set frequency for pumping your septic tank.  Varying uses and lifestyle will dictate how often you should have your septic tank pumped.

We no longer use time as an indicator of need for pumping.  Instead, we check the total accumulated volume of solids at the time of inspection to make this determination.

When there is 18" of total accumulated solids or anytime the crust/scum layer on top is 6" or more, it is time for a pumping of the system.

The best plan is to have a regularly scheduled inspection and only pump when your system requires it.  

How Often Should I Have My System Inspected?

State and County laws both require that your septic system is regularly maintained.  See the next question down!

How Often Should I Have My System Inspected?

State and County laws both require that your septic system is regularly maintained.

  • If you have a pressurized system (if your system uses a pump instead of gravity), it must be inspected yearly.
  • If you have a gravity or conventional septic system, it must be inspected every 3 years.

Can I just inspect my system myself?

Yes.  We don't recommend this for most homeowners, however.  See the next question!

Can I inspect my own septic system?

In most instances, yes.  In others, no.

When you Can't Inspect Your Own System

If you are using any of the following proprietary systems, you may NOT inspect it yourself:

  • FAST
  • Whitewater
  • Glendon
  • Low-e OSCAR

These system types all require a maintenance agreement with a properly licensed and certified professional.

What Does it Take to be able to Inspect My Own Septic System?

How often should I clean my septic system filter?

Generally, once per year is enough for an average household.  In some rare cases, your system may require it more often.

If you have a pressurized system

You will need an annual inspection.  Our service includes the filter cleaning.

How do I know if I have a filter?

In order to explain this, we would have to write a book!  Sorry!  Just call us.

If I don't have a filter, should I have one?

Yes!  We always recommend this, as long as you have risers!  Having a filter helps to screen the effluent before it moves to the drain field or pump tank.  The cleaner the effluent to the drain field / pump tank, the greater the longevity of your drain field.

What is a septic system riser and should I have one?

A septic system riser is an addition that installs on the inlet and outlet sides of the tank.

Septic system risers provide easy access to the septic tank at the ground level.  This will save you money in the long run, because it will eliminate the cost to dig up the tank for pumping or maintenance.
