Storage Tank Kit Components

RO System — Commercial-grade, 300–7,000 GPD with integrated prefiltration to extend membrane life.
Water Storage Tank — Atmospheric tank (165, 220, or 500 gallons) sized to your system and available space.
Pump — Delivers purified water from the tank to your home on demand.
Float Switches — Automatically cycles the RO system on/off based on tank water level.

Note: Additional shipping charges may apply for orders with 500-gallon storage tanks.

Optional Add-Ons

UV Water Sterilizer (12 GPM)

Adds an extra layer of protection against microbiological contamination downstream of the RO system.

Alkalizing Postfilter

Enhances alkalinity, mineralization, and oxidation of purified water before it enters your home.

Remineralizer System

Adds essential minerals back into purified water and adjusts pH to prevent damage to plumbing and fixtures from acidic RO water.
