Troubleshooting
Problem
Little or no water delivered .
Bleeder orifice check valve
stuck or installed backwards
(standard tank only).
Low water level.
Low voltage.
Plugged intake screen.
Check valve at pump
discharge stuck.
Worn impellers and diffusers.
Air or milky water discharge from faucets .
Gas in well water.
Air volume control not
working (standard tanks
only).
Check
Examine valve.
Determine lowest water level in well
while pump is running and compare
to pump depth setting.
Check voltage at pressure switch
with pump running. Check incoming
wire size and drop cable size against
Cable Sizing tables.
Pull pump and check condition of
screen.
Pull pump and examine check valve.
Make sure system is clear of
obstructions and pump is in solid
water and operation normal.
Check for presence of gas in well

Corrective Action
If stuck, free valve; if installed
backwards, reverse it.
Lower pump further into well (but
at least 5' (1.6m) above bottom
of well). Throttle pump discharge
until discharge equals recovery rate
of well.
NOTICE Running pump while
airlocked can cause loss of prime and
seriously damage pump.
Install larger wire from meter to
pressure switch. Install larger wire
from pressure switch to pump. If
necessary, have power company raise
supply voltage.
Clean or replace as necessary.
Free check valve.
Replace pump.
Remove bleeder orifices; plug tees.
Be sure plugged tees do not leak.
If necessary, separate gas from air
before it enters pressure tank.
Replace control if necessary.
