DISCHARGE PIPE AND PRESSURE TANK CONNECTIONS
Connecting Pump Discharge to Pre-Charged
Tank Connections (Figure 5)
1. Install tee 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, a pressure gauge or pressure control
valve.
5. Check the air pressure in the tank using an ordinary tire
gauge. The air pressure should be 2 PSI less than the
cut in setting of the pump's pressure switch. The
pre-charge tank's pressure is measured when
there is no water in the tank. 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 pres
sure in the tank should be set at 28 PSI, (30-2)
6. Fill pump body with water.
7. 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.
