5 - Avoiding footprints, place In-Drains with painted stripe facing up, end to end on sand in trench or bed.
Caution: Spacer cores can have sharp edges

6 - Center 4" perforated distribution pipe over
In-Drains. Use solid pipe over compacted sand
from D-Box to In-Drains and to connect distribution
lines at far end. Connect mid-points on rows
over 40' long.

9 - Place 12" medium to coarse sand (see step #4) between rows and 6" min. at the sides in trench or bed. (Example: Right)

10 - Complete backfill and loam to 12" min. over In-Drains. Fill should be clean, porous and devoid of large rocks. Use well graded sandy fill with a maximum 10% passing a #200 seive. Do not use wheeled equipment over system. A light track machine may be used with caution, avoiding crushing or shifting of pipe assembly. Backfill in direction of perforated pipe.

11 - Divert surface runoff. Finish grade to prevent surface ponding. Seed loam and protect from erosion.

7 -Secure pipe with one Eljen clamp per In-Drain. Slide clamp into upfacing core. Force through fabric into sand.
