PRE-CHARGE TANK CONNECTION
(FIGURES 4 AND 5)
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
requires one tee.
2. Run a pipe or reinforced hose from one arm of the
first 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 ordi-
nary 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 teflon tape for making all threaded connec-
tions 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.
