SPRAY & PUMP FAQ
1. Why does the pump not run all the time?
This is an on- demand pump and only runs with flow; spray wand, by-pass, spray tips
or leak in system.
2. Why does the pump surge while using the spray wand?
Low flow/high pressure may cause the pump to surge (or cycle). This could happen
when the spray wand is adjusted for a small or fine spray pattern. To overcome, adjust
the nozzle for higher flow.
3. How do I adjust the pressure?
Pressure can only be adjusted by adjusting the nozzle.
4. My pump quit and will not restart - what should I check?
Check all electrical connections. Ensure switch is in the on position. Check in-line fuse.
Ensure correct voltage (12-13 volt).
5. Low flow or no flow at all - what should I check?
Check for a clogged suction hose and/or suction strainer. Often you will need to clean
the suction strainer. Check for proper voltage. Check filter in shut-off.
