Fountain Nozzle and Diffuser Nightly Soak SOP

Nightly procedure for disassembling fountain nozzles and diffusers, soaking them in sanitizer, rinsing, drying, and reassembling to prevent mold and yeast buildup in beverage dispensing equipment.

Steps

• The operator verifies the work area is clear and sanitizer is ready
  Confirm the work area is free of obstacles and the approved food-contact sanitizer is mixed to the site-required concentration using a test strip. Record the sanitizer reading on the daily log before starting.
• The operator shuts down beverage dispensing flow
• The operator removes the nozzle and diffuser
• The operator inspects the removed parts for damage or buildup
  Inspect each part under good light for cracks, warping, missing pieces, or heavy residue. Remove any damaged part from service and record the issue in the log.
• The operator soaks the nozzle and diffuser in sanitizer
  Submerge the nozzle and diffuser in approved sanitizer at the label-specified concentration and temperature, keeping the solution between 65–75°F when required by site procedure. Maintain the soak for 60–90 seconds or the sanitizer label contact time, whichever is longer.
• The operator rinses the parts if the sanitizer label requires it
  Rinse the parts with potable water only when the sanitizer label or site procedure requires a rinse after contact time. Do not rinse when the label says no rinse is needed.
• The operator dries the parts completely
  Place the parts on a clean towel or air-dry rack until they are dry to the touch and no visible moisture remains inside the nozzle or diffuser.
• The operator reinstalls the nozzle and diffuser
  Reinstall the parts so they seat fully, align correctly, and do not wobble or leak when lightly checked by hand.
• The operator verifies proper fit and documents completion
  Run a brief flow check to confirm the nozzle sits secure, dispenses evenly, and shows no leaks. Record completion and any defects or replacements in the daily log.
