NOTICE: Packer jets (2" and 3" single pipe wells) do not form a perfect
seal. Normal irregularities in the cup seal leather and the inner walls of the
casing will allow the pressure in a dormant system to leak off over time.
This will cause the pump to cycle periodically to maintain the system

times in order to get all the trapped air out of the piping. Don't for-
get to close the control valve each time before you start the pump.
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.
