Piping:
Use at least
To avoid strains on the pump, support both suction and discharge pipes inde- pendently. Place these supports near the pump.
To avoid a strain left by a gap at the last connection, start all piping at the pump and run pipe away from the pump.
To avoid airlocking, slope suction pipe slightly upward toward the pump.
NOTICE: To prevent flooding when removing pump for service, all flooded suction systems must have gate valves in suction and discharge pipes.
Fittings:
Fittings restrict flow; for best efficiency use fewest possible fittings.
Avoid fittings which could cause an air trap.
Pool fittings must conform to International Association of Plumbing and
Mechanical Officials (IAPMO) standards.
