Although the BIB system is designed to be maintenance -free, on rare occasions there will be problems
with the system. In most cases, it will be associated with one of the four following areas:
1. Vacuum leaks/air in the system. Leaks that occur between the BIB and inlet of pump.
2. Syrup leaks. Usually occur at the pump or at the outlet line between the pump and the dispenser.
3. Gas Leaks. Usually occur between the CO2 cylinder and the pump or from air in the BIB.
4. Stalls. May be due to over pressurization. Ensure proper gas pressure and proper regulator
operation.
The table below outlines fault conditions and a list to check for possible causes.
Condition
Pump does not operate
with gas applied
(dispenser valve open)
Pump operates but will
not prime
(dispenser valve open)
Pump does not achieve
Sold-out with empty
BIB
Air in inlet or outlet
tubing
Pump strokes with
dispenser valve closed
Fluid from exhaust or
visible within the gas
inlet tubing
Gas blowing from
exhaust continuously
Trouble-shooting
Check the following
•
BIB empty.
•
Inlet tubing pinched thus activating "sold-out" feature of pump.
•
Gas regulator over-pressurizing.
•
Outlet tube kinked or restricted.
•
Operated without fluid for excessive period. (Dry run)
•
Transfer tube and gas lines contaminated (syrup, rust, oil, etc.)
Ensure clean gas supply, change out all contaminated.
•
Internal damage of control cover
Consult Start-up Procedure for proper priming
•
Pump valves have no moisture/dry.
Add water to the inlet port with pump stroking slowly.
•
Vacuum leaks at Q.D., barb fitting clamps, or inlet fitting o-ring.
•
Debris in valve seats or warped/swollen valves
•
Vacuum leaks at Q.D., barb fitting clamps, or inlet fitting o-ring
•
Excessive amount of air in BIB from improper packaging.
•
Air trapped in outlet tubing and/or fluid chambers.
•
Vacuum leaks at Q.D. o-ring or barb fitting clamps
•
Vacuum leaks at inlet fitting; o-ring pinched or missing.
•
Large amounts of air noticed only in the outlet tubing when
pump operates. Diaphragm/piston assemblies ruptured.
• Air trapped in outlet tubing and/or fluid chambers.
Open outlet and purge air, check for vacuum leaks, or air in BIB
•
Debris in outlet valves or warped/swollen valves.
•
Carbonator check valve
•
Ensure clean gas supply
•
Diaphragm/piston assemblies ruptured
change out all contaminated pumps
•
Control cover subjected to contaminated gas supply or
damaged.
Ensure clean gas supply, change out all contaminated pumps
