How we repair your Carbonator
A carbonator is a pump and tank assembly that pressurizes filtered water with CO2 to make the carbonated water fed to soda fountains and beverage towers. A carbonator combines a water supply or reservoir, a pump or fill valve, a heating element or boiler, thermostats and safety cutoffs. A technician checks water flow, scale buildup, heating and temperature control, and seals and gaskets.
In cafes and offices a down brewer or espresso machine stops sales immediately, so commercial beverage repairs are scheduled fast.

Common Carbonator problems we fix
What usually causes each symptom, and what our technician checks to confirm it.
Low carbonation at the valves
- Likely causes
- Low CO2 pressure, a worn pump vane delivering little flow, or a check valve letting water back into the CO2 line.
- What our technician checks
- CO2 and tank pressures are measured and the check valves are tested.
Water leaking from the tank or fittings
- Likely causes
- Loose fittings, a worn relief valve, or a damaged tank seal.
- What our technician checks
- The system is pressurized and fittings and the relief valve are checked for leaks.
Loud or grinding pump
- Likely causes
- Running dry, worn pump vanes, or a misaligned motor coupling.
- What our technician checks
- Pump output and coupling alignment are checked and the pump is inspected for wear.
Pump runs nonstop
- Likely causes
- No water supply, a failed level probe or float switch, or a leak in the carbonated water line.
- What our technician checks
- The technician checks incoming water, tests the level control, and inspects lines and fittings for leaks.
Pump will not start
- Likely causes
- A failed pump motor, a tripped thermal overload, a bad relay or control board, or a level control stuck reading full.
- What our technician checks
- Voltage is tested at the motor and board, and the level control and overload are checked.
Relief valve hissing or venting
- Likely causes
- CO2 regulator set too high, a failed relief valve, or a pump pushing water above set pressure.
- What our technician checks
- Regulator pressure and tank pressure are measured and the relief valve is tested.
Quick checks you can do safely
- Confirm the water supply valve and filter are open and not clogged.
- Check the CO2 tank level and regulator gauge.
- Listen for the pump running dry or cycling nonstop.
- Look for drips at visible fittings and the water filter housing.
- Reset the pump overload if the unit has an external reset.
Safety first: The tank and CO2 lines are under pressure, so close the CO2 supply and bleed system pressure before opening fittings.
