For Professional Technical Support call 1-844-242-2475
Possible Cause
1. The switch is off.
2. There is a blown fuse or tripped
breaker.
3. The pressure switch contacts
are dirty.
4. The wires at the motor are loose
or wired incorrectly.
1. The pump was primed
improperly or air is trapped in
the pipe.
2. There is an air leak.
3. The water level is below the
suction pipe inlet.
4. The foot valve is plugged or
leaks.
1. The foot valve is buried in sand
or mud.
2. The ejector or impeller is
plugged.
3. The foot valve or inlet strainer is
clogged.
4. The water level is below the
maximum lift specification.
5. The voltage is not correct.
6. The pressure control valve is
not set up correctly.
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.
7. Standard pressure tank
(Conventional Type) is
waterlogged, and has no air
cushion.
1. Water level is lower than
estimated.
2. The pipes leak.
3. The pressure switch is not set
correctly.
4. Venturi, nozzle or impeller is
clogged.
Corrective Action
1. Turn the power switch on.
2. Replace the fuse or reset the circuit breaker.
3. DISCONNET THE POWER. File or clean the
switch contacts.
4. DISCONNECT THE POWER.
Follow the wiring instructions to check and
tighten the wires.
1. DISCONNECT THE POWER. Adjust pump
height and make the pipe slope down to the
well. Remove the discharge tee and
re-prime.
2. Check all connections and fix the leakage.
3. Lower the suction pipe. If the water level is
more than 25 ft., use deep well installation.
4. Clean or replace the foot valve.
1. Lift the suction pipe.
2. Clean the ejector or impeller.
3. Clean or replace as necessary.
4. Select a convertible jet pump.
5. Check the voltage switch.
6. Readjust the pressure regulator.
1. Add or release air as needed.
2. Replace the tank/refill the air.
Test the tank by depressing the air valve.
The air valve will expel water if the bladder is
broken.
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.
7. Drain tank to air volume control port, check
AVC for defects.
1. Use a deep well installation.
2. Locate and repair the leak or reconnect.
3. Reset or replace the pressure switch.
4. Remove the pump body and seal plate,
observe it
