My field lines only, not the tank, has roots that need to be killed. The m ost common treatment seems to be copper sulfate, and it's expensive. Salt i s much cheaper(.50c/lb for table salt) and it will kill roots. With an acce ss pipe at the output of the tank/input to field, anything can be dumped do wn it. Has anyone tried putting salt into the field lines?
Don't know but clean-out guy says salt is bad for concrete in line.
Roots don't seem to be a problem with my field although I had removed trees too close to the tank drain line.

I heard salt was bad for concrete but field lines are free of concrete. Th e lines are surrounded by gravel but that should not be a problem.
Many trees have roots that only grow under the tree but other type trees ca n grow roots several hundred feet beyond the tree line. Sweet gum is like t hat and that's my problem. I killed the trees and the roots are still grow ing & putting up shoots. Spray the shoots with roundup, they die, but anot her shoot will pop up nearby.
