Priming the Deep Well Pump
To prime pump, completely close the priming valve located
just below the suction opening by turning screw clockwise.
This valve will be left closed during operation in a deep well
installation. See Figure 1.
Close regulator adjusting valve, located on end of regulator,
by turning stem clockwise. See Figure 1.
Remove priming plug from top of regulator valve, see Figure
1, and fill with clean water. Replace plug.
Start pump and run a few moments.
If pressure does not build up, remove priming plug and refill
with more water. All of the trapped air in pump body was not
removed.
Restart pump.
When pump is completely primed and builds up pressure,
slowly open the regulator valve, (turn counter-clockwise), and
observe the pressure reading on the pressure gauge.
When the pump reaches a point where it will lose prime, cavi-
tation noise can be heard.
The best, or correct, pressure gauge setting is approximately
3 pounds higher than the pressure gauge reading was when
the pump started to lose prime.
If pump loses prime, repeat the priming procedure above and
this time open regulator valve only until the correct pressure
reading is reached.
If a vacuum gauge is available, screw it into the 1/8” AVC
tapping on front of tank body. Adjust regulator until 20” of
vacuum is registered on the gauge. Tighten locknut on regu-
lator. This method will give maximum performance of the
unit.
