Corrective Action
1.
Ensure the switch is on.
2.
Replace the fuse or reset circuit breaker.
3.
DISCONNECT POWER; check and tighten all
wiring.
4.
DISCONNECT POWER and clean the electrical
contacts.
1.
Check with the power company and install heavier
wiring if the wire size is too small.
2.
See the section below on the pump cycling too
frequently.
1.
In new installation:
a)
Re-prime according to instructions.
b)
Check all connections on the suction line, AVC,
and ejector with shaving cream.
c)
Replace the foot valve or check valve.
2.
In installation already in use:
a)
Check all connections on the suction line and
well seal.
b)
Lower the suction line into water and re-prime.
If receding water level in the well exceeds 25 ft.
(7.6 M), a deep well pump is needed.
3.
Clean the foot valve or strainer.
4.
Clean the ejector or impeller.
5.
Replace the check valve or foot valve.
6.
Thaw pipes. Bury pipes below the frost line. Heat
the pit or pump house.
7.
Raise a foot valve and/or strainer above the bottom
of the water source. Clean the foot valve and
strainer.
8.
A deep well pump may be needed (over 25 ft. to
water) to deliver water.
1. A deep well jet will be needed if your well is more
than 25 ft. (7.6 M) depth to water.
2. Replace with plastic pipe where possible, otherwise
with new steel pipe.
3. Use larger piping.
4. Backflush the well point or sink new point.
1.
DISCONNECT POWER; adjust or replace the
pressure switch.
2.
Close the faucets.
3.
Clean the venturi, nozzle or impeller.
4.
Drain the tank to air volume control port. Check AVC
for defects. Check all connections for air leaks.
5.
Check the connections.
6.
Replace the foot valves.
7.
DISCONNECT POWER and open faucets until all
pressure is relieved.
Using a tire pressure gauge, check air pressure in
the tank at the valve stem located on the tank. If
necessary, adjust air pressure in the tank to 28 PSI
(2 PSI lower than switch cut-in setting). Check the
air valve for leaks (use shaving cream) and replace
core if necessary.
