Pre-Charge Tank Connection
To Household
Water System
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
Relief
pipe or reinforced hose from one arm of the tee to the port on the pre-
Valve
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
From
Well 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 tubing 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.

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
From tight. If the suction pipe can suck air, the pump will not be able
Well
to pull water from the well.
