How Often Should I Get My Septic Tank Pumper?

Most tanks should be pumped every 3-5 yrs, however this may vary depending on the tank size, number of people in the home and water usage. A family of 6 is presumably going to need their tank pumped out more frequently than a family of 4 with the same sized septic tank. Better to be ahead of the game rather than behind in this scenario!

Do you pump everything out of the tank?

More Info

Because it is impossible to completely empty the tank, there will be some liquid left on the bottom though this should be minimal. The contents remaining in the tank contain bacteria that will continue to promote breakdown of incoming waste.

Why clean my septic tank?

More Info

Your septic tank seperates solids from wastewater and allows the wastewater to travel through the system to the absorbtion field. A dirty tank allows more solids to enter the absorbtion field which inturn will plug your drain field causing the system to fail.

Do I need to be there when you clean my tank?

More Info

You are not required to be present during the service, but we  strongly recommend that if you have questions or concerns that you visit with us during the service or give us a call afterwards to discuss them. We are happy to answer any questions you have.
