*Note:
Cartridge life is directly dependant on water conditions and volume of water filtered. Excessive sediment may cause more frequent
replacement. Contaminants reduced by these filters/cartridges are not necessarily in your water.
** Caution:
It is highly recommended to replace sumps at least once every 5 years to prevent costly repairs or possible water damage.
Record date of installation of new sump at the bottom.
