Pre-Charge Tank Connection
1. Install a close nipple and a tee in the pump discharge port. The
pipe size must be at least as large as the discharge port. Run a pipe or
reinforced hose from one arm of the tee to the port on the pre-charged tank.
2. Install a second close nipple and tee with a relief valve in the tee.
3. Connect the other end of the second 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.
You have just completed the tank connection for your jet pump. Please go
to Pages 9 and 10 for electrical hookup.
Standard Tank Connection
1. Install a close nipple and a tee in the pump discharge port. Mount a
relief valve in one arm of the tee.
2. Install a second close nipple and tee in the open arm of the first tee. Put
a priming plug in one arm of the second tee.
3. Run a pipe from the open arm of the second tee to the inlet port of your
tank. The pipe size must be at least as large as the pump dischargeport.
4. 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.

Sealing Pipe Joints
Use only PTFE pipe thread sealant tape or PTFE-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.
