Tank Pre-Charge

NOTICE: Be sure that power to the pump is OFF when checking the tank’s precharge.

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. Please go to Electrical for electrical hookup.

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.
