As RO systems age, their components can start to malfunction leading to frustration and much time wasted trying to repair or replace various parts. Prevent the problems of an old RO system and avoid buying a whole new system by using this retrofit kit. This kit allows you to keep using your current tank and faucet, and only replace the manifold (main component that holds all the filters). The GRO-75 Reverse osmosis 4-Stage system is a high efficiency under sink reverse osmosis system that sets the standard for water-efficient reverse osmosis systems. Its enclosed RO membrane efficiently flushes contaminants, achieving a 50% recovery rate or 1:1 waste water ratio. This under-sink RO system delivers 75 gallons of clear, crisp drinking water daily. With the capacity to eliminate up to 99% of 90+ impurities, including lead, TDS, VOCs, chlorine, and Arsenic V, the GRO-75 greatly improves the taste and odor of your drinking water. Its user-friendly design facilitates easy installation and filter replacements.

  • Conserves Water: RO recovery rate of 1:1 rather than the typical 4:1 waste water ratio. The system uses 50% less water than other systems.
  • Plenty of Water: Produces up to 75 gallons per day of clean, healthy water for your household. Incorporates highly advanced thin layer composite (TLC) membrane technology for supreme water quality.
  • Effective Filtration: High-efficiency reverse osmosis technology removes up to 99.99% of 90 contaminants, including fluoride, heavy metals, chlorine, herbicides, and more.
  • Quick Installation: The system is designed for straightforward installation, potentially reducing setup time and costs.
