Troubleshooting Chart
Symptom(s)
Fuses blow or overload protector
trips while motor is running
Pump starts too frequently
Little or no water pumped
air, milky, or tea colored water
discharge from faucets
Possible Cause(s)
1. Low or high voltage
2. ambient temperature too high
3. Control box uses wrong voltage
or horsepower rating
4. Wire size too small
1. Leaks in system
2. Defective pressure switch or
switch out of adjustment
3. Leak in check valve(s)
4. Waterlogged tank
5. Leak in drop pipe
6. Pressure switch is too far from
tank
1. Check valve stuck or installed
backwards (standard tank only)
2. Low water level (water source)
3. Low voltage
4. Clogged intake screen
5. Check valve at pump discharge
stuck
6. Worn impellers and diffusers
7. Cracks or leaks in pipe
1. Gas in well water
2. air volume control (aVC) not
working properly (standard tanks
only)
3. Recent Shocking Well
Deep Well Submersible ump
Corrective action(s)
1. If voltage variation is greater than 10% of nameplate rating,
call power company to adjust voltage.
2. Check temperature of control box. If necessary, move pump
out of direct sunlight.
3. Replace control box if voltage and horsepower ratings on
control box nameplate do not match those shown inside box
cover.
4. Install wire of correct size.
1. Check tank connections with soapy water. Check plumbing for
leaks. ensure system is airtight and watertight.
2. adjust or replace pressure switch.
3. Replace if needed.
4. Pre-charged tanks: adjust air pressure to 2 psi (13.8 kPa) less
than cut-in pressure. Replace bladder if needed.
Air-over-water tanks: Repair or replace tanks. Replace air
volume control (aVC) if needed.
5. Raise drop pipe by increments of one length until water stands
in pipe. Replace pipe above that point.
6. Position switch within 1 foot (0.3 m) of tank.
1. If stuck, free valve. If installed backwards, reverse valve
position.
2. Determine lowest water level in well while pump is running.
Compare to pump depth setting. Lower pump further into
well, but at least 5 feet (1.5 m) from bottom of well. throttle
pump discharge until discharge equals recovery rate of well.
Running pump while airlocked
CAN cause loss of prime and serious
damage to pump.
3. Install larger wire from meter to control box. Install larger wire
from control box to pump. Have power company raise supply
voltage if needed.
4. Clean or replace if needed.
5. Free check valve.
6. Make sure that system is clear of debris and that pump is
running normally in clear water. If there are no obstructions in
system, replace pump.
7. Replace as necessary
1. Remove air release ports and plug tees. Make sure that
plugged tees do not leak. If necessary, separate gas from air
before it enters pressure tank.
2. Make sure ports and ball check valves are clear. Replace air
volume control if needed.
3. Pump out well to remove chemicals. test for chemicals in
water, to determine when flushing is complete.
