Should I compact the System Sand after I put it in place?

No. After System Sand is spread between rows it is recommended that the installer straddle each row of pipe and walk heel-to-toe its entire length, ensuring that System Sand fills all void spaces beneath the AES or Enviro-Septic® pipe. Pneumatic tired equipment and/or mechancial compactors should not be used to compact System Sand, fill or fill extension areas. Mechanical compaction will damage the soil’s ability to disburse liquid and may inhibit oxygen supply to the system.
