Preparing to Start the Pump – Deep Well
A-Open Control Valve
B-Watch for Pressure Gauge to Flutter
C-Close Control Valve until Pressure
Stabilizes

Step 6. After the pump has built up pressure in the system and shut off,

walls of the casing, packer jets do not form a perfect seal. In a dormant sys-
tem, pressure will leak off over time, causing pump to cycle periodically to
maintain system pressure level.

50 PSI, slowly open the control valve (see Figure 11) and let the
pressure drop until the pressure gauge needle starts to flutter. When
the needle flutters, close the valve just enough to stop the flutter
(see Figure 11). Your pump is now operating at its most efficient
point.
check the pressure switch operation by opening a faucet or two and
running enough water out to bleed off pressure until the pump
starts. The pump should start when pressure drops to 30 PSI and
stop when pressure reaches 50 PSI. Run the pump through one or
two complete cycles to verify correct operation. This will also help
clean the system of dirt and scale dislodged during installation.
