Troubleshooting (continued)
The pump starts too
frequently.
There are leaks in the system.
Check all tank connections with soapsuds for air leaks.
Check plumbing for leaks. The system must be air and water
tight.
The pressure switch is defective.
Check for a defective switch or switch out of adjustment. Re-
adjust or replace the pressure switch.
The tank is waterlogged.
Pre-charged tanks; check tank pre- charge air pressure and
check for leak in the bladder. adjust air pressure to 2 PSI
(13.8 kPa) less than the pump cut-in pressure (when there is
no water pressure on system). Replace the bladder if
necessary.
Air over water tanks: check for air leaks. Check Air Volume
Control (AVC). Check snifter valve operation. Repair or replace
tanks; replace snifter valves if necessary.
There is a leak in the drop pipe.
Raise the drop pipe one length at a time until water stands in
the pipe. Replace the pipe above that point.
The pressure switch is too far from the tank.
Measure the distance from the pressure switch to the tank.
Move the switch to within 1 ft. of the tank.
Little or no water is being
delivered.
The bleeder orifice check valve is stuck or
installed backwards (standard tank only).
Examine the valve. If stuck, free the valve; if installed
backwards, reverse it.
The water level is low.
Determine the lowest water level in the well while the pump
is running and compare to the pump depth setting. Lower the
pump further into the well (but at least 5 ft. (1.6M) above the
bottom of the well). Throttle the pump discharge until the
discharge equals the recovery rate of the well. NOTICE:
Running the pump while airlocked can cause loss of prime
and seriously damage the pump.
The voltage is low.
Check the voltage at the control box with the pump running.
Check incoming wire size and power supply wire size against
the tables in the Wiring section of this manual. Install a larger
wire from the meter to the control box. Install a larger wire
from the control box to the pump.
If necessary, have the power company raise the supply
voltage.
The intake screen is plugged.
Pull the pump and check the condition of the screen. Clean or
replace as necessary.
Check to see if the valve at the pump discharge
is stuck.
Pull the pump and examine the check valve. Free the check
valve.
Impellers and diffusers are worn.
Make sure the system is clear of obstructions and the pump
is in solid water and operating normally. Replace the pump.
The is air or a milky
water discharge coming
from the faucet.
There is gas in the well water.
Check for the presence of gas in the well water. Remove
bleeder orifices; plug tees. Be sure plugged tees do not leak.
If necessary, separate gas from air before it enters the
pressure tank.
The air volume control is not working (standard
tanks only).
Make sure ports and ball check valves are clear. Replace the
control if necessary.
