VI – Adjusting the System for Maximum Performance
1. Using the pressure gauge included with the CaviBlaster power unit
, (figure # 30)
the water pressure will need to be higher to account for sidewall friction loss in the
pressure hose. The pressure at the pump should be 2,800-psi plus 0.75-psi per foot of
pressure hose.
For example, if using the CaviBlaster with 100 feet of pressure hose, the pressure gauge
located next to the pump should indicate 2,875-psi. Pressure adjustments are made in
the pressure regulator by turning the nuts of the green spring. There should always be a
trickle of water through the bypass when the gun trigger is in the open or “ON” position.
2. Using a calibration pressure gauge between the pressure hose and the
CaviBlaster gun,
(figure # 34) (
Not included with the unit
) the water pressure should be
2,800-psi with the gun submerged and the gun trigger in the open or “ON” position.
The pressure is adjusted by turning the nuts on the end of the pressure-regulating
unloader (Figure # 30). This adjustment increases or decreases the flow of water through
the bypass hose when the CaviBlaster gun trigger is in the open or “on” position.
The flow of water through the bypass hose, in turn, determines the flow of water
through the pressure hose and the gun. Less flow through the bypass hose means more
flow through the gun which translates to higher velocity and pressure. There should
always be a trickle of water through the bypass when the gun trigger is in the open or
“ON” position, this ensures that the bypass will open without a pressure shock wave
damaging the pump when the gun trigger is released to the closed position.
3. Without a pressure gauge
, close the pressure-regulating unloader until there is just
a trickle of water (less than ¼ gallon per minute) coming out of the bypass with the gun
trigger in the open or “ON” position.
