1. Completely drain all water
from tank by turning off pump
and opening a faucet until
water stops.
2. Use a pressure gauge to ensure
it’s set to 18 psi.
a. Use a tire pump to adjust the
psi to 18 psi

CAUTION: All pumps must be primed by lling the cavity with water before they are rst operated. This will take several gallons of
water, as the suction line must be lled in addition to the cavity of pump. Depending on the length of suction pipe, many gallons may be
needed to ll the entire system.
Pressure Gauge or
Discharge tee plug
Vent plug
a. Remove pressure gauge or discharge
tee plug (not included) from the top of the
discharge tee (not included). Remove the
vent plug in front of the discharge tee.
b. Slowly ll the discharge tee with water
until water overows the vent plug
opening. NOTE: Before turning on
pump, loosely replace vent plug and open
several outlets or faucets to allow water
ow during priming.
c. Check to be sure water in the cavity

of pump stays constant. If water level
goes down, it could indicate a leak in
the foot valve, check valve or suction
pipe. If water remains constant, wrap the
pressure gauge or discharge tee plug and
vent plug threads with thread tape and
thread into pump. Tighten with wrench
(not included).
