corrected by exchanging two 3-phase power wires
at input power terminal block then recheck each
pump separately.

Tank Overflows
Some tank overflows have external 2" PVC
connections. These connections may be plumbed to an
open trough or floor drain.
IMPORTANT: Connections made to the overflow
must provide adequate support for weight of pipe
and fittings.
Tank damage. Connections made to the
overflow must point downward from the
tank. Routing plumbing upward will damage
tanks.
