TROUBLESHOOTING CHART (Continued)
SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
E. PUMP 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
F. 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 alignment
6. Air change too low in pre-charged
tank
1. Drain tank to air volume control tapping. Check
air volume control for defect. 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 the valve stem located at top of tank. Air
pressure should be 2 PSI below pump pressure
switch cut-in setting. Check air valve for leaks,
using soapy solution, and replace core if
necessary.
G. AIR SPURTS FROM
FAUCETS LITTLE OR
NO
WATER
1. Pump is picking up prime
2. Leak in suction side of pump
3. Well is gaseous
4. Intermittent over-plumbing of well
1. As soon as pump picks up prime, all air will be
ejected
2. Check suction piping
3. Change installation as described in manual
4. Lower foot valve if possible, otherwise restrict
discharge side of pump to match well delivery
