3. Thermal Protection cut out.
4. Blocked impeller.
1. Pump not primed.
2. Lift height exceeded.
3. Inlet tube not submerged.
4. Air in suction pipe.
5. Inlet screen clogged.
1. Inlet pipe is too small.
2. Liquid is too dirty.
3. Lifting height exceeded.
4. Tank's rubber bladder under-inflated.
5. Piping corroded, causing friction.
Cut-in and cut-out pressure
may be set too closely.
1. Air inlet valve is leaking.
2. Bladder is broken.
Water level is being drawn below foot valve.
1. Foot/check valve not installed
in suction line.
2. Foot/check valve leaks water back to well.

2. Reduce lift height.
3. Submerge the inlet.
4. Check pipe and seals.
5. Clean screen.
1. Increase pipe diameter.
2. Clean screen frequently.
3. Reduce lifting height.
4. Inflate to 23 PSI.
5. Replace piping, with plastic
where possible.
Cut-in and cut-out pressure may be set
too close together. Have the pressure
switch adjusted by a qualified technician.
Have the pressure switch adjusted

1. Temporary self-remedying issue.
2. Check for and fix leaks.

4. Lower suction line into water
and re-prime. If water is deeper
than Maximum Suction Lift, then a
deep well pump may be needed.
