Introducing the RainDance RDCW-1000 & RDCW-2000 Whole House Reverse Osmosis Systems for City Water

9/27/2025

 
​When it comes to clean, safe, and reliable water for your home, not all reverse osmosis systems are created equal. That’s why RainDance Water Systems is proud to introduce our new RDCW-1000 and RDCW-2000 Whole House Reverse Osmosis Packages, designed specifically for municipal city-treated tap water. These advanced RO systems combine high-capacity purification with environmentally friendly, low-maintenance pretreatment to deliver the highest quality water to every tap in your home.
​Why Choose Whole House Reverse Osmosis for City Water?
Even though city-treated water is disinfected, it often contains a wide variety of unwanted impurities, including salts, fluoride, chlorine, chloramines, nitrates, PFAS, pharmaceuticals, and microplastics. Over time, these contaminants can affect water taste, impact health, and cause damage to plumbing and appliances.

A whole house reverse osmosis system goes beyond point-of-use filters by providing purified water to your entire home—every shower, faucet, and appliance. With the RainDance RDCW series, you’ll enjoy consistent, great-tasting water that’s free of a wide spectrum of contaminants.
​Salt-Free Hard Water Scale Prevention: Maintenance-Free Protection
One of the standout features of the RDCW-1000 and RDCW-2000 packages is the no-salt, environmentally friendly hard water conditioner. Unlike traditional water softeners that require heavy salt bags and frequent maintenance, this advanced pretreatment provides chemical-free scale prevention.
  • Protects & Extends the life of the RO membranes by pretreating limescale and hard mineral deposits. 
  • Protects plumbing, fixtures, and appliances from corrosion and buildup.
  • Extends the lifespan of the RO system without adding sodium to your water.
  • Zero maintenance required—no salt, no chemicals, no monthly upkeep.
This innovative pretreatment is the first stage in the RainDance system, ensuring maximum efficiency and long-term reliability.
​Inside the RDCW Whole House RO Packages
Both the RDCW-1000 (1,000 gallons per day) and RDCW-2000 (2,000 gallons per day) are engineered to meet the needs of families of all sizes. Each system includes a comprehensive multi-stage design:
  1. No-Salt Hard Water Conditioner – Salt-free, maintenance-free scale prevention to protect the RO system.
  2. Carbon Pretreatment Filter – Removes chlorine and chloramines used in city water disinfection.
  3. High-Capacity RO Membranes – Reduce salts, heavy metals, fluoride, nitrates, pharmaceuticals, PFAS, microplastics, and more.
  4. Post pH Correction – Balances RO water to keep it non-acidic, protecting plumbing and fixtures.
  5. Storage Tank – Collects purified water since RO produces water in a slow, steady stream.
  6. Repressurization Pump – Delivers purified water back to your home at full household pressure.
  7. Post-UV Disinfection – Neutralizes bacteria and microorganisms for added peace of mind.
