So, I got my input and output riser panels installed on my tank yesterday. My tank looks like an interesting design, has a concrete divider and then some type of concrete "cone" that the output pipe is inside of. I started digging around my leach field, looks like at the head of each line there is a ball valve so I can turn off individual lines. Might give me some interesting options for restoration. Going to go ahead and buy an SepticAir Aid aerator to install next Saturday. Hoping that works.
