TANK PRE-CHARGE
NOTE:
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 Page 8 for electrical hookup.
WINTERIZING THE PUMP
To prepare the pump for freezing temperatures:
Step 1. Shut off power to the pump.
Step 2. Relieve system pressure. Open a faucet and let it
drain until water stops flowing.
Step 3. Drain the pump. Your pump may have a separate
drain plug. Remove this plug and let it drain.
Your pump may only have a plug or connection
on the side of the pump. Remove this and let the
pump drain. Some water will remain in the
pump. A small amount of water left in the pump
will not harm it if it freezes.

Sealing Pipe Joints
Use only Teflon tape or Teflon based joint com-
pounds for making any threaded connections with
plastic pipe.
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.

1. Tank nearly empty – air expands filling area above
vinyl water cell.
2. Water begins to enter tank – air is compressed
above water cell as it fills with water.
3. Pump-up cycle completed – air now compressed
to cut off setting of pressure switch.
4. Water being drawn from tank – compressed tank
air forces water out of water cell.
5. Water cell completely empty – new cycle ready
to begin.
