- Backflow Into Concentrate
-
Cause: Eductor check valve inoperable
Solution: Clean or replace check valve - Discharge From Backflow Preventer Vent
-
Cause: Backflow preventer check valve dirty or defective Water hammer condition in supply system (cause of "splitting") Negative pressure in supply line causing reverse flow
Solution: Clean or replace backflow preventer (Kit #105) Install water hammer shock arresters or water pressure reducing valves - Excess Concentrate Draw
-
Cause: Metering tip not in place (or wrong metering tip)
Solution: Press correct tip firmly into barb - Leaks At Plastic And Copper Junctions
-
Cause: Compression nut loose
Solution: Tighten nut 1/2 turn - Leaks At Plastic Tube
-
Cause: Compression nut loose
Solution: Tighten nut 1/2 turn - Low Or No Water Flow
-
Cause: Inlet screen clogged
Solution: Clean or replaceCause: Supply source inadequate
Solution: 4 GPM flow necessary to operate unit; move unit or replumb incoming lineCause: Scaled eductor or fittings
Solution: Clean* or replace* In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit that are exposed to water. This scale may be removed by soaking the eductor in a descaling solution (deliming solution). To remove an eductor located in the cabinet, firmly grasp water valve and unthread eductor. Replace in same manner. Alternatively, a scaled eductor can be cleaned (or kept from scaling) by drawing the descaling solution through the unit. Operate the unit with the suction tube in the descaling solution. Operate the unit until solution is drawn consistently, then flush the unit by drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.
- No Concentrate Draw
-
Cause: Clogged check valve
Solution: Clean or replaceCause: Metering tip clogged
Solution: Rinse in hot water or replace: DO NOT REAM CLEAN!
Cause: Eductor clogged
Solution: Clean or replaceCause: Clogged water inlet
Solution: Clean screenCause: Clogged foot strainer
Solution: Clean or replaceCause: Low water pressure and/or volume
Solution: Replace with full containerCause: Check valve not screwed into eductor firmly
Solution: Tighten, but DO NOT OVERTIGHTEN!* In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit that are exposed to water. This scale may be removed by soaking the eductor in a descaling solution (deliming solution). To remove an eductor located in the cabinet, firmly grasp water valve and unthread eductor. Replace in same manner. Alternatively, a scaled eductor can be cleaned (or kept from scaling) by drawing the descaling solution through the unit. Operate the unit with the suction tube in the descaling solution. Operate the unit until solution is drawn consistently, then flush the unit by drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.
- No Discharge
-
Cause: No water
Solution: Open water supplyCause: Excessive water pressure
Solution: Install regulator if water pressure exceeds 85 PSI (flowing)Cause: Eductor clogged
Solution: Clean* or replace* In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit that are exposed to water. This scale may be removed by soaking the eductor in a descaling solution (deliming solution). To remove an eductor located in the cabinet, firmly grasp water valve and unthread eductor. Replace in same manner. Alternatively, a scaled eductor can be cleaned (or kept from scaling) by drawing the descaling solution through the unit. Operate the unit with the suction tube in the descaling solution. Operate the unit until solution is drawn consistently, then flush the unit by drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.
- Water Flow Won't Shut Off
-
Cause: Ball valve defective
Solution: Replace - Weak Foaming Action
-
Cause: Clogged water inlet strainer
Solution: Clean or replaceCause: Water pressure too low
Solution: Minimum 25 PSI requiredCause: Water temperature too high
Solution: Use lower temp water source (Concentrate flow decreases above 140 degrees F water) - Weak Spraying Action
-
Cause: Clogged water inlet strainer
Solution: Clean or replaceCause: Water pressure too low
Solution: Minimum 25 PSI required
