FLUID SYSTEM DIAGNOSTICS - Flow and Pressure
PROBLEM POSSIBLE CAUSE SOLUTION
No Flow
No power Make sure pump is operating. Check drive belts and
couplings, make necessary adjustments.
Trigger gun valve Check trigger gun, repair or replace.
No water source Ensure water supply is not restricted and hoses are in
good repair and not kinked.
Clogged spray nozzle Check spray nozzle, repair or replace.
Clogged inlet filter Check inlet filter, repair or replace.
Float Valve stuck (optional) Float valves can become stuck in the "UP" position.
Manuallydislodge and inspect for problems.
Faulty unloader valve Remove and check for proper action, repair or replace.
Low pressure, adequate
flow
Incorrect or no spray nozzle
Nozzle should be properly sized for the system. Low
pressure indicates that the nozzle in use is
too large.
Worn spray nozzle Replace nozzle when it shows signs of internal erosion.
Debris in valves Clean valves and check o-rings for pits and cracks.
Lance on low pressure Adjust pressure so the water flows through properly.
Unloader is not adjusted correctly Adjust unloader to proper level.
Pressure gauge inaccurate
Use a new pressure gauge on a quick connect at outlet to
check system pressure and replace if
gauge is faulty.
Pump packings bad If low pressure persists, pump packings may need
replaced.
Low pressure, low flow
Volume Improperly adjusted If unit has volume adjustment, it may need readjustment
Discharge leaks Look for leaks on the discharge side of system.
Downstream chemical injector
(Dema)
Remove the injector and retest system. If the flow is
restored, replace the injector.
Loose drive belts If belts do not have proper deflection, replace them.
Pump not running at rated speed Check engine throttle and see that the motor is rated for
the same speed as the pump.
Stripped pump drive coupling Inspect coupling and repair or replace.
Defective easy start valve
(optional)
Check the start or throttle-back valve for proper operation.
Malfunctioning motor or gear Ensure that the motor or engine is working properly
Unloader stuck in bypass Piston assembly may be stuck or fouled
Low pressure, low flow
- Bogs
Outlet restriction
Build up can restrict flow. If water is not flowing freely,
flush with garden hose to isolate the clog
or restriction.
Clogged nozzle Distorted spray pattern can indicate a clogged nozzle.
Nozzle too small Ensure nozzle is proper size for the system.
Hose restriction Correct any kinks or restrictions. Replace crushed hoses.
Debris in the system
Debris can lodge in the discharge side of the system
(valves, fittings, injectors, filters) Flushing
with water may correct it.
