DISCHARGE PIPE AND PRESSURE TANK CONNECTIONS
Connecting Pump Discharge to Pre-Charged
Tank Connections (Figure 5)
1. Install two tees in the pump discharge port. The pipe
size must be at least as large as the discharge port.
2. Run a pipe from one arm of the tee in the pump's
discharge port to the end of the tee installed in the
pre-charged tank.
3. Connect the other end of the tank tee to your
plumbing system.
4. Cap the remaining openings in the tees with a
threaded plugs or a pressure gauge.
5. Check the air pressure in the tank using an ordinary tire
gauge.
6. The air pressure should be 2 PSI less than the cut in
setting of the pump's pressure switch.
7. The pre-charge tank's pressure is measured when
there is no water in the tank.
8. For example, if your pump has a 30/50 PSI pressure
switch, your pump will turn on when the pressure in
the line drops to 30 PSI (cut in pressure) and will turn
off when the pressure in the line increases to 50 PSI
(cut out pressure). The air pressure in the tank should
be set at 28 PSI, (30-2)
9. Fill pump body with water.
10. Go to Electrical section.

Connecting Pump Discharge to Standard Tank
(Figure 6)
1. Install two tees in the pump discharge port.
2. Run a pipe from one arm of the tee installed in the
pump's discharge port to the end of the tee installed in
the tank.
3. Connect the other end of the tank tee to your plumbing
4. Install in another opening of the pump tees a reducer
bushing down to 1/8" NPT in the tee.
Run tubing from the tee to the port on the Air Volume
Control (AVC) mounted on the tank.
5. Cap the remaining openings with a threaded plug or
pressure gauge.
6. Seal all joints with PTFE pipe thread sealant tape
or a PTFE-based pipe joint compound. See instructions
provided with the tank and the AVC for details.
7. Pour water in the pump.
8. Go to Electrical section.

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.
