septic line blockage

In January we had our tank pumped because of stinky yard puddles. The problem never really went away. Last week, the an inspector from the county came and said we had a blockage in the line and needed to run a 3" pvc pipe from first D box to second box since those lines weren't being 'fed'. The first D box is less than 6' from an oak tree. The opposite side is wrapping around two smaller trees (unknown species). The system is 10 years old. We are pulling up the trees in an attempt to get the roots too. My questions are: 1-do you think the oak may be giving the problem? 2-Do you think the two saucer magnolias planted 3 years ago over the lines (I was having a blonde day when I planted them) may be the problem? Finally - do you think commercial 'root killer' additives work? Thank you very much in advance.

NC rural real estate broker here, and I deal with septic systems frequently. Also have lived with home on one for 24 years. Sounds like roots are your problem. Flush one lb. of copper sulphate (blue crystals-comes in 3-lb bags) down about every four months. Kills roots in lines, and keeps others out. Don't bother using any of those "boosters", like Rid-X, etc. They are a waste of money. You can use plain old household yeast to boost system, if you want to, but copper sulphate is an absolute must to keep your system root-free. Good Luck!
