Pre-Charge Tank Connection
1. Install two tees in the pump discharge port (see Figure 4). The pipe size
Pump Priming
must be at least as large as the discharge port.
Tee and Plug
2. Run a pipe or reinforced hose from one arm of the first tee to the port
From Well
on the pre-charged tank.
3. Connect the other end of the discharge tee to your plumbing system.
Cap the tee with a threaded plug or a pressure gauge.
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. Adjust the tank pre-charge pressure to 28 PSI for a
model CJ90E pump (30/50 pressure switch), or to 38 PSI for a model
CJ90F pump (40/60 pressure switch).
Congratulations! You have just completed the tank connection for your jet
pump. Please go to Page 7 for electrical hookup.

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.
