DISCHARGE PIPE AND PRESSURE TANK CONNECTIONS
PRE-CHARGE TANK CONNECTION
1.
Install two tees in the pump discharge port (Figure 4). The
pipe size must be at least as large as the discharge port.
2.
Run a pipe or reinforced hose from one arm of the first tee
to the port on the pre-charged tank.
3.
Connect the other end of the discharge tee to your plumb-
ing system.
4.
Check the pre-charge of air in the tank with an ordinary tire
gauge. The pre-charge should be 2 PSI less than the cut-in
setting of the pump's pressure switch. The pre-charge is
measured when there is no water pressure in the tank. Your
new pump has a 30/50 PSI switch, so adjust the tank pre-
charge pressure to 28 PSI.
5.
Proceed to the Electrical section for hookup information.

SEALING PIPE JOINTS
Use only PTFE pipe thread sealant tape for making all threaded connections to the
pump itself. Do not use pipe joint compounds on plastic pumps as they can react with
the plastic in pump components. Make sure that all pipe joints in the suction pipe are air
tight as well as water tight. If the suction pipe can suck air, the pump will not be able to
pull water from the well.

STANDARD TANK CONNECTION
1.
Install one tee in the pump discharge port (Figure 5).
2.
Run a pipe from the pump discharge port to the inlet port
of your tank. The pipe size must be at least as large as the
discharge port.
3.
Remove the 1/8" NPT pipe plug from the pump Air Volume
Control (AVC) port. Run tubing from the pump's AVC port to
the port on the AVC mounted on the tank. See instructions
provided with tank and AVC for details. AVC port location
will vary, depending on your pump model (Refer to Parts
Index).
4.
Proceed to the Electrical section for hookup information.
