PRE-CHARGE TANK CONNECTION (Figure 12)
To Household
Water System
Step 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
Relief
port. Run a pipe or reinforced hose from one arm of the tee to the
Valve
port on the pre-charged tank.
Step 2. Install a second close nipple and tee with a relief valve in the tee.
From
Step 3. Connect the other end of the second discharge tee to your plumb-
Well
ing system.
Step 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)
Step 1. Install a close nipple and a tee in the pump discharge port. Mount a
relief valve in one arm of the tee.
Step 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.
Step 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.
Step 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.

Well
Sealing Pipe Joints
Use only Teflon tape or Teflon based joint compounds for mak-
ing 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 suc-
tion pipe can suck air, the pump will not be able to pull water
from the well.
