DISCHARGE PIPE AND PRESSURE TANK CONNECTIONS
PRE-CHARGE TANK CONNECTION
Install two tees in the pump discharge port. The pipe size must be at least as large as the discharge port.
NOTE:
A pre-plumbed pump-on-tank system only requires one tee.
Run a pipe or reinforced hose from one arm of the first tee to the port on the pre-charged tank.
Connect the other discharge tee to your plumbing system.
Check the pre-charge of air in the tank with an ordinary tire gauge.Your new pump has a 30/50 PSI switch, so adjust
the tank pre-charge pressure to 28 PSI. The pre-charge is measured when there is no water in the tank. The
pre-charge should be 2 PSI less than the cut-in setting of the pump’s pressure switch.
Congratulations! You have just completed the tank connection for your jet pump.
NOTE:
Sealing Pipe Joints. Use only teflon tape for making all threaded connections to the pump itself. Do not use pipe
joint compounds on plastic: they can react with the plastic. 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
Install a tee in the pump discharge port.
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.
Install a tee with reducing bushings in the suction pipe as shown.
Install a barbed fitting in the smallest bushing (1/8" NPT).
Run the AVC tubing from the barbed fitting on the suction pipe tee to the port in the AVC mounted on the tank. See
the instructions provided with the tank and the AVC for details. The AVC port location may vary.
Congratulations! You have just completed the tank connection for your jet pump.
