APPENDIX — RECOMMENDED SHOTCRETE SYSTEM
GENERAL RECOMMENDATIONS
If the site will permit, use steel pipe from the pump to
the pool perimeter. It will reduce line pressures which is
highly recommended.
The vibrator on the reducer by the pool improves
pumpability.
Turn both air vibrators off whenever the pump is stopped
to prevent separation of mix.
The air vibrators are low consumption (4.2 scfm).
Leave the air on at the nozzle when the pump is stopped
to prevent clogging of air the hoses in the air insert.
Use item #11 (steel elbow) at the edge of the pool to
prevent collapse of the rubber hose, which can cause
blockage.
