• Why is my Hydro dispenser not drawing concentrate?

  Common causes include a clogged foot valve, scale build-up in the metering tip or eductor, low water pressure (min 25 psi required), or an empty concentrate container. Check the inlet strainer and ensure the discharge tube is firmly in place.

• How do I clean a clogged eductor?

  In hard water areas, scale may form inside the eductor. Remove the eductor and soak it in a descaling (deliming) solution. Alternatively, operate the unit with the suction tube in descaling solution to draw it through the system, then flush with clear water.

• How do I determine the correct metering tip for dilution?

  Consult the tip chart in your specific user manual (e.g., AccuMax or SinkMaster). For thick products, perform a measurement of concentration test by operating the primed dispenser for one minute and calculating the ratio of mixed solution to concentrate drawn.

• What are the water pressure requirements for Hydro units?

  Most Hydro dispensing units require a minimum dynamic water pressure of 25 psi to operate correctly and a maximum of 85 psi. Higher pressures may require a regulator.
