Discharge Pipe and Pressure Tank Connections
6
PRE-CHARGE TANk CONNECTION
(FIGURE 4)
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.
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
plumbing 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.
Congratulations! You have just completed the tank
connection for your jet pump.

STANDARD TANk CONNECTION
(FIGURE 5)
1. Install one tee in the pump discharge port
(see 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 (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
location will vary, depending on your pump model
(see exploded view, Page 11).
Congratulations! You have just completed the tank
connection for your jet pump.

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: 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.
