PRE-CHARGE TANK CONNECTION (Figure 4)
Step 1. Install two tees in the pump discharge port (see Figure 4). The pipe
size must be at least as large as the discharge port.

Step 2. Run a pipe or reinforced hose from one arm of the first tee to the
Tee with Plug
port on the pre-charged tank.

Step 3. Connect the other end of the discharge tee to your plumbing system.
From Well
Cap the tee with a threaded plug or a pressure gauge.
Step 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.
Congratulations! You have just completed the tank connection for
your jet pump.
Please go to Pages 7 and 8 for electrical hookup.
STANDARD TANK CONNECTION (Figure 5)
Step 1. Install one tee in the pump discharge port (see Figure 5).
Step 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.
Step 3. Remove the 1/8" NPT pipe plug from the pump Air Volume Control
(AVC) port (see Figure 5). Run tubing from the pump's AVC port
(see Figure 5) to the port on the AVC mounted on the tank. See
instructions provided with tank and AVC for details. AVC port loca-
tion will vary, depending on your pump model (see exploded
views, Page 10).
Congratulations! You have just completed the tank connection for
your jet pump.
Please go to Pages 7 and 8 for electrical hookup.
Use only Teflon tape or Teflon based joint compounds for
making all threaded connections to the pump itself. Do not use
pipe joint compounds on plastic pumps: 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.
