Top 10 - What Is The Best Whole House RO System For Well Water

What Size Whole House Reverse Osmosis System Do I Need?
Sizing your RO system correctly is crucial for ensuring adequate water supply. A common formula for determining the size is:

Calculate Daily Water Usage: Estimate your household's daily water consumption.
Apply the Sizing Formula: Use 100 gallons per day (GPD) per person, plus additional capacity for miscellaneous uses. Double this number to accommodate future needs.

For example, if your household uses 400 GPD, you should consider an RO system with an 800 GPD capacity. This ensures you have enough purified water for continuous use and any future increases in demand.

Who Installs the Whole-House Reverse Osmosis System?
Installation is typically completed by a qualified local plumber, water-treatment professional, contractor, or other experienced installer. RainDance provides detailed installation instructions, and our technical support team is available to answer questions from your installer before, during, and after installation.
Customers with substantial plumbing, electrical, and water-treatment experience may also be capable of completing the installation. However, due to the size and complexity of a whole-house reverse osmosis system, professional installation is strongly recommended.
