Discharge Pipe and Pressure Tank Connections 8

PRE-CHARGE TANK CONNECTION (Figure 12)

1.Install a close nipple and a tee in the pump discharge port (see Figure 12). The pipe size must be at least as large as the discharge port. Run a pipe or reinforced hose from one arm of the tee to the port on the pre- charged tank.

2.Install a second close nipple and tee with a relief valve in the tee.

3.Connect the other end of the second discharge tee to your plumbing system.

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. 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.

You have just completed the tank connection for your jet pump. Please go to Pages 9 and 10 for electrical hookup.

STANDARD TANK CONNECTION (Figure 13)

1.Install a close nipple and a tee in the pump discharge port. Mount a relief valve in one arm of the tee.

2.Install a second close nipple and tee in the open arm of the first tee. Put a priming plug in one arm of the second tee.

3.Run a pipe from the open arm of the second tee to the inlet port of your tank. The pipe size must be at least as large as the pump

discharge port.

4.Remove the 1/8" NPT pipe plug from the pump Air Volume Control (AVC) port (see Figure 13). Run tub- ing from the pump’s AVC port to the port on the AVC mounted on the tank. See instructions provided with tank and AVC for details.

Sealing Pipe Joints

Use only Teflon tape or Teflon based joint com- pounds 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.
