7.0 TROUBLESHOOTING
Problem
Probable Cause
Remedy
Failure to
Pump
1. Leak in suction side of pump
2. Valve seats not sealing
3. Low setting on pump
4. Low suction level
5. Diaphragm ruptured
6. Pump head cracked or broken
7. Pump head contains air or chlorine gas
8. Breakdown or disconnection of wiring
9. Voltage drop
10. Malfunction of electronic control board
1. Examine suction tubing. If worn at the end, cut
approximately one inch (2.5cm) off and reconnect
2. Clean valve seats if dirty or replace with alternate
material if deterioration is noted
3. When pumping against pressure, the dial should
be set above 20% capacity for a reliable feed rate
4. Solution must be above foot valve strainer
5. Replace diaphragm as shown in 6.0 Maintenance
Section. Check for pressure above rated maximum
at the injection point. NO
TE” Chemical
incompatibility with diaphragm material can cause
diaphragm rupture and leakage around the pump
head
6. Replace pump head as shown in 6.0 Maintenance
Section. Make sure fitting are hand tight only. Using
pliers and wrench can crack pump head. Also,
chemical incompatibility can cause cracking and
subsequent leakage.
7. Bleed pump head, see 5.0 Start-up and Operation
section
8. Connect wiring properly. Check fuse or circuit
breaker
9. Take measures after investigation of cause
10. Contact supplier
Loss of
Chemical
Residual
1. Pump setting to low
2. Scale at injection point
3. Solution container allowed to run dry
1. Adjust to higher setting (pump must be operating
to adjust stroke length knob)
2. Clean injection parts with 8% muriatic acid or
undiluted vinegar (also, see Maintenance Section)
3. Refill the tank with solution and prime (see Start-
up and Operation Section)
Too Much
Chemical
1. Pump setting too high
2. Chemical in solution tank too rich
3. Siphoning of chemical into well or main
line
1. Lower pump setting (pump must be operating to
adjust stroke length knob)
2. Dilute chemical solution. NOTE: For chemical that
reacts with water, it may be necessary to purchase a
more dilute grade of chemical direct from chemical
supplier
3. Test for suction or vacuum at the injection point.
If suction exists, install an anti-siphon valve
