Replace when the yellow or red light is on, water flow is slow or weak, taste or smell returns, or after 12 months / ~3,000 gallons, depending on water quality and usage levels.

Yes. Running 2–3 gallons through a new 51300C (about 3–5 minutes) removes loose carbon fines and ensures optimal taste from day one.

Regularly wipe the bottle filler nozzle and sensor with a mild cleaner (e.g., diluted bleach or Elkay-approved sanitizer) to prevent buildup and minimize false low-flow alerts.

In facilities with heavy sediment, adding the Elkay EWFPF5M Pre-Filter can significantly extend the life of your 51300C by catching larger particles before it reaches your main filter.

Using an Elkay bottle filling station with a 51300C filter helps dramatically reduce single-use plastic waste. Just one bottle filling station can save up to 15,000 plastic bottles and 327 lbs of plastic from landfills every year—while delivering approximately $3,750 in annual cost savings compared to purchasing bottled water.
