Why & When You Should Replace the Filter
Elkay specifies replacing the 71300C filter every 2,250 gallons or 1 year, whichever comes first. Staying on schedule ensures the cartridge continues to perform within its NSF/ANSI certified limits - skipping it puts water quality at risk.
⚠️ Note: In high-traffic facilities such as schools, gyms, and airports, the 2,250-gallon capacity may be reached well before the 12-month mark. This information is based on real-world usage estimates, not official manufacturer data.

Troubleshooting & FAQ
The New 71300C Filter Is Leaking — What's Wrong?
The cartridge likely isn't fully seated. Remove it, reinsert firmly into the head, and turn 1/4 turn right until it locks and the front label is clearly visible.
The Old 71300C Filter Is Hard to Remove.
Confirm the water supply is off and pressure is relieved by dispensing water. Then turn the filter a firm 1/4 turn to the left to release it from the head.
Flow Is Slow After Replacing the 71300C Filter.
This usually means air is trapped in the system. Complete the full 3-minute flush to purge air and fine carbon particles. Also confirm the supply valve is fully open.
The Indicator Light Won't Reset to Green.
Reset behavior depends on your station model — some reset automatically, others require a manual reset. Check your station's user manual for the exact procedure.
⚠️ Note: Indicator reset behavior is governed by the host station, not the 71300C cartridge spec sheet.
