This photograph is of what the inside of a AK500 F looks like after tree roots have infiltrated. This needs to be closely monitored as it can do severe damage to the tank and internal components. This homeowner was advised to remove trees that were adjacent to where this system had to be installed, because the roots had destroyed his previous tank. He did not comply with our request, and recommendation of both us and Public Health. The result after 11 years is seen above.

Do not plant trees in close proximity to your septic system, tanks, and lines. Irreparable damages can result. 

Warranty, or extended service plans do NOT cover damage done by tree roots.
