An engine will lose approximate 3.5% of its power per every 1000 feet above
sea level. If the elevation of operation was not considered when the unit was
selected, a unit of higher horsepower may be required to make the needed
performance.
Restriction
If a new strainer and/or intake hose was purchased, check that they provide
adequate supply to the pump to meet the performance desired.
If the pump was purchased used, check that the actual configuration will
achieve the desired performance. A
WATERAX
Inc. representative can be
contacted for assistance.
Check pump lift. Refer to “Pump Loses Prime or Will Not Prime: Suction Lift
Too High” section.
Pump Cavitating
Lift Too High
Move pump closer to water source.
Decrease pump’s intake hose length.
Increase pump’s intake hose size (inner diameter).
Water
Temperature
Water temperature may be too high. Water temperatures approaching 35°C
(95°F) or higher are likely to cavitate the pump. Decrease engine speed
and/or gate the discharge valve to decrease pump flow until the cavitating
stops.
Locate a cooler water source.
Restrictions
Refer to “Restrictions” in the “Pump Does Not Make Performance” section.
Check that the bottom of the suction hose a minimum of 2 feet (0.6 meters)
from the bottom of the water source and correct if necessary.
Check that the bottom of the suction hose/strainer is 4 to 6 times the hose
diameter below the water supply surface level and correct if necessary.
Engine Speed Too High for Required Capacity and Pressure
Air Leaks
Refer to “Pump Loses or Will Not Prime: Air Leak” section.
