Problem(s)
Possible cause(s)
Suggested solution(s)
Pump does not
deliver water to full
capacity (also check
point 3 immediately
above).
1. Water level in well is lower
than estimated.
2. Steel piping (if used) is corroded or
limed, causing excess friction.
3. Offset piping is too small in size.
1. A deep well jet may be needed (over 25 ft.
to water).
2. Replace with plastic pipe where otherwise
with new steel pipe.
3. Use larger offset piping.
Pumps water, but
does not shut off.
1. Pressure switch is out of adjustment
or contacts are frozen.
2. Faucets have been left open.
3. Ejector or impeller is clogged.
4. Water level in well is lower
than estimated.
1. Adjust or replace pressure switch.
2. Close faucets.
3. Clean ejector or impeller.
4. Check possibility of using a deep well jet pump.
Pump cycles
too frequently.
1. Standard pressure tank is
waterlogged and has no air cushion.
2. Pipes leak.
3. Faucets or valves are open.
4. Foot valve leaks.
5. Pressure switch is out
of adjustment.
6. Air charge too low in
pre-charged tank.
1. Drain tank to air volume control port. Check air
volume control for defects. Check for air leaks
at any connection.
2. Check connections.
3. Close faucets or valves.
4. Replace foot valve.
5. Adjust or replace pressure switch.
6. Disconnect electrical power and open faucets
until all pressure is relieved. Using automobile
tire pressure gauge, check air pressure in tank
at valve stem located at top of tank. Pressure
should be 2 psi less than the cut-in pressure
of pump pressure switch. If necessary, add air
pressure with an air hose. Check air valve for
leaks, using a soapy solution, and replace core
if necessary.
Air spurts from
faucets, little or
no water.
1. Pump is picking up prime.
2. Leak in suction side of pump.
3. Intermittent over-pumping of well.
1. As soon as pump picks up prime,
all air will be ejected.
2. Check suction piping.
3. Lower foot valve if possible, otherwise restrict
discharge side of pump.
