CAUTION: All pumps must be primed by filling the cavity with water before they are first operated. This will take several gallons of
water, as the suction line must be filled in addition to the cavity of pump. Depending on the length of suction pipe, many gallons may be
needed to fill the entire system.

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 fill the discharge tee with water
until water overflows the vent plug
opening. NOTE: Before turning on
pump, loosely replace vent plug and open
several outlets or faucets to allow water
flow 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).

Connect pump to tank (not included) as
shown. Most pressure tanks will have a 1 inch
inlet elbow on the bottom. Using 1 in. fittings
(not included), connect this elbow to pump as
shown. A union (not included) is recommended
for easy connection.

Air pressure in the tank must be 2 PSI lower than the
“cut-in” of the pressure switch. Pump has a 20/40
PSI pressure switch, so tank pressure must be set
at 18 PSI. Check pressure with a tire gauge (not
included) and add or subtract air as needed.
Remove plastic plugs from
inlet and outlet openings.
