Priming The Pump - Waterax MINI-STRIKER MSTR-P Owner's Manual

WATERAX MINI-STRIKER Owner's Manual
Barometric pressures below 98 kPa (29 in of Hg) can also cause noticeable loss

in pump performance (specifically elevations >2000 feet above sea level).
Pump performance curves are based off a 5 foot lift (top of water source to

impeller center). Lifts greater than 5 feet will decrease the pump's performance.
Hose and strainer sizes that are too restrictive can significantly decrease the

pump's performance.
Intake hose runs in excess of 10 feet can also reduce pump performance.

Drafting connections
1. Connect a suction line to the pump intake.
2. Install a footvalve suction strainer on the other end of the suction hose and place in
the water source.
Note:
To provide proper operation of the pump, the suction hose/strainer should be submerged
a minimum of 4 to 6 times the hose diameter into the water source.
DO NOT allow footvalve strainer to rest on bottom of lake or riverbed. Check strainer
frequently to make sure that it is not clogged with moss, leaves, etc.
DO NOT lift strainer from water while the pump is operating. Use a rope or other means to
keep strainer at proper height, approximately 1 foot (30 cm) below water surface. If
strainer is too close to the water surface, it will draw air and pump may lose prime.

Priming the Pump

Before priming the pump, discharge hoses should be installed. Several options are
available to prime a pump when you are drafting water, depending on the priming
equipment you have.
Note:
The priming line must be connected to a port on the pump that allows the eye of the
impeller to completely fill with water. A shut off valve should also be placed between the
pump and the primer to shut off the priming line once the pump has been primed.
Connect hand primer to discharge port and pump until water is drawn into the

pump.
Pump can also be primed by "jerking" the suction hose until water flows from the

pump's discharge port.
