To prevent _ <br /> accumulation of water, do not allow any "bellies"or low points <br /> in the vent piping. Keep the 2"vent piping less than 20'in total <br /> length. ;Y <br /> . � {� <br /> IC <br /> Step 11a: Backfill the excavation. Follow the tank <br /> manufacturer's guidelines for backfilling the tank, if you have <br /> not already done so. <br /> Step 11b: Backfill and compact around the AdvanTex pod in <br /> maximum 12" lifts.Native material is acceptable if there are no, <br /> large or sharp rocks that may damage the filter walls. If native <br /> material is not usable,backfill with sand or pea gravel. Slope <br /> the ground away from the pod to prevent surface water from <br /> ponding on or around the pod. <br /> Be careful when backfilling not to alter the slope of pipes. Brace <br /> the pipes and carefully fill around them. <br /> NIM-AIX-AX-1 0 2004 Orence Systemse Inc. <br /> Rev 11,OWN <br />
