Cap the tee with a threaded plug or a pressure 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.

the port on the AVC mounted on the tank. Seal all joints with PTFE
pipe thread sealant tape. See instructions provided with the tank
and the AVC for details.
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 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.
