Discharge Pipe and Pressure Tank Connections
PRE-CHARGE TANK CONNECTION
(FIGURE 4)
1. Install two tees in the pump discharge port (see Figure 4).
The pipe size must be at least as large as the discharge
port.
NOTE: A pre-plumbed pump-on-tank system only re-
quires one tee.
2. Run a pipe or reinforced hose from one arm of the fi rst
tee to the port on the pre-charged tank.
3. Connect the other discharge tee to your plumbing system.
4. Check the pre-charge of air in the tank with an ordinary
tire gauge.Your new pump has a 30/50 PSI switch, so adjust
the tank pre-charge pressure to 28 PSI. The pre-charge is
measured when there is no water in the tank. The pre-
charge should be 2 PSI less than the cut-in setting of the
pump's pressure switch.
Congratulations! You have just completed the tank con-
nection for your jet pump.

Sealing Pipe Joints
Use only tefl on tape for making all threaded connections
to the pump itself. Do not use pipe joint com-
pounds on plastic: they can react with the plastic.
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.
