systems problem. Almost every other problem will be related
to electrical issues.
The most common electrical problems are poor connections.
Among those: Corroded battery terminals, corroded ground
wire, corroded wire connector, inadequate wire size for load
and damaged wire.
Our 12 volt motors with switches have circuit breakers built
into the switch box.

IMPortANt: Warranty void if you connect electrical wires
backwards. Red is positive (+). Black is negative (-). Retrace
electrical wires to battery to be absolutely certain (+) terminal
on battery goes to red motor wire. Black wire on motor goes
directly to (-) terminal on battery or truck frame.
iNLEt CONDitiON CHECkLiSt
Inadequate inlet conditions can cause serious malfunctions in
the best designed pump. Surprisingly, the simplest of things
can cause the most severe problems or go unnoticed to the
unfamiliar or untrained eye. REVIEW THIS CHECKlIST BEFORE
OPERATIOn OF AnY SYSTEM. Remember, no two systems are
alike so there can be no OnE best way to setup a system. All
factors must be carefully considered.
iNLEt SUPPLy should exceed the maximum flow being
delivered by the pump to assure proper performance.
• Open inlet shut-off valve and turn on water supply to avoid
starving the pump. DO nOT RUn PUMP DRY.
• Avoid closed loop systems especially with high temperature,
ultra-high pressure or large flows. Conditions vary with
regulating/unloader valve.
• When using an inlet supply reservoir, size it to provide
adequate liquid to accommodate the maximum output of
the pump, generally a minimum of 6-10 times the gPM
(however, a combination of system factors can change this
requirement).
iNLEt LiNE SizE
should be adequate to avoid starving the
pump
• line size must be a minimum of one size larger than the pump
inlet fitting. Avoid tees, 90-degree elbows or valves in the
inlet line of the pump to reduce the risk of flow restriction
and cavitations.
• The line MUST be a FlEXIBlE hose, nOT a rigid pipe, and
reinforced on SUCTIOn systems to avoid collapsing.
• The simpler the inlet plumbing the less the potential for
problems. Keep the length to a minimum, the number of
elbows and joints to a minimum (ideally no elbows) and the
inlet accessories to a minimum.
• Use pipe sealant to assure airtight, positive sealing pipe
joints.
iNLEt PrESSUrE should fall within the specifications of
the pump.
• High RPM, high temperatures, low vapor pressures or high
viscosity may increase acceleration loss of liquids.
• Optimum pump performance is obtained with +20 PSI (1.4
BAR) inlet pressure. With adequate inlet plumbing, most
pumps will perform with flooded suction.
