Symptom
Pump starts too fre-
quently
Little or no water
pumped
Air, milky, or tea colored
water discharge from
faucets
Possible Cause(s)
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 dis-
charge 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 Pump
Corrective Action
1. Check tank connections with soapy water. Check plumb-
ing 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 run-
ning. Compare to pump depth setting. Lower pump fur-
ther 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
NOTICE
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 obstruc-
tions 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.
