Possible Cause
1. The tank was pre-charged
incorrectly.
2. There is a ruptured
diaphragm/bladder (pre-charged
tank)/or has no air cushion.
3. The pipes are leaking.
4. The foot valve leaks.
5. The pressure switch is not adjusted
correctly.
6. The air charge is too low in the
pre-charged tank
1. Water level is lower than estimated.
2. The pipes leak.
3. The pressure switch is not set
correctly.
Possible Cause
Impeller blocked or debris goes around
impeller.
1. Did not prime.
1. The tank was pre-charged incorrectly.

Corrective Action
1. Add or release air as needed.
2. Replace the tank/refill the air.
3. Repair the pipe connections or replace the
pipes.
4. Repair or replace the foot valve.
5. Closely look at the pressure gauge to see
the pump On/Off points are around
30 psi/50 psi. If not, adjust or replace the
pressure switch.
6. DISCONNECT POWER and open faucets
until all pressure is relieved. Using tire
pressure gauge, check air pressure in the
tank at the valve stem located on the tank.
If less than pressure switch cut-in setting
(30 psi), pump air into the tank from an
outside source until air pressure is 2 psi
less than the cut-in setting of the switch.
Check the air valve for leaks (use soapy
solution) and replace core if necessary.
1. Use a deep well installation.
2. Locate and repair the leak or reconnect.
3. Reset or replace the pressure switch.
Corrective Action
Disassemble pump and clean debris.
1. Please fill water into pump to prime.
1. Add or release air as needed.
2. Replace the tank/refill the air.
3. Repair the pipe connections or replace
the pipes.
4. Repair or replace the foot valve.
5. Closely look at the pressure gauge to
see the pump On/Off points are
around 30 psi/50 psi. If not, adjust or
