To calculate the hole depth required, add the package depth plus the amount of bedding used under the tank, then
subtract 2 inches.
Package depth plus bedding thickness minus two inches = Hole depth required.
BEDDING MATERIAL

compacted bed of round or angular crushed rock with a
minimum size of 1/8” and no larger than ¾”. The bedding
should be placed and compacted using a hand or vibratory
