PUMP PRIMING & STARTUP
Deep Well Application Only:
CAUTION: All pumps must be primed (filling the
cavity with water) before they are first operated. This
may take several gallons of water, as the suction line will
be filled in addition to the pump cavity.
1. Remove the 1/2” priming plug. (

4. If pump is properly primed, pressure will quickly build
and register on the gauge mounted directly on the
pump body. If pressure does not build repeat priming
operation. All air must be vented from the drive and
suction pipes as well as the body before the pump will
prime. The pump body may need to be filled several
times in order to achieve the prime. (
