Cartridge Replacement


REPLACING THE CARTRIDGE

To maintain your water quality, the eSpring cartridge must be replaced once a year or once every 5,000 liters (1,320 gallons) of water, whichever comes first. If your water contains large amounts of particulates, you may need to change the cartridge more often to maintain an acceptable flow rate. The eSpring monitor features a “gas gauge” type indicator that shows the remaining cartridge life.

EARLY WARNING: ORDER A NEW CARTRIDGE

​When 90% of the rated life of the cartridge is remaining (based on time or the amount of water that has flowed through the system), the monitor will sound a single audible tone and a bar will flash whenever water is flowing. This reminds you to order a new cartridge.

SECOND WARNING: REPLACE THE CARTRIDGE

​At 100% of the rated life of the cartridge, a different continuous audible tone will sound, and the reminder bar disappears, the replace cartridge appears in red and center cartridge flashes. This tells you it’s time to replace the cartridge. The sophisticated monitoring system makes sure you will never change the cartridge prematurely or wait too long which can negatively affect your water quality.

WHY DOES THE CARBON BLOCK FILTER NEED REPLACEMENT?

​The tiny pores in the activated carbon of each eSpring filter act as contaminant "traps.” Even if you do not use 5,000 liters (1,320 gallons) of water over the course of a year, large organic molecules in standing water around the carbon block will begin to clog the pores over time. When that happens, smaller contaminants could slip over the blocked pores instead of being trapped inside them. So when you hear the alert tone, change the cartridge. This ensures your eSpring Water Treatment System will keep providing you the high water quality it has been tested and certified to deliver.
