The RainDance Advantage for High-Sulfate Well Water

  • Built for Tough Conditions: The Sulfate Eater "Smart Series" adapts to seasonal or intermittent changes in well water sulfate levels, providing consistent, reliable filtration.
  • Sulfate Health Risks: High sulfate levels in drinking water (above 250 mg/L) can cause dehydration and diarrhea, especially in infants, the elderly, and those with health conditions. For livestock, it can lead to weight loss and can corrode plumbing. Our Sulfate Eater brings sulfate levels below 250 mg/L, often down to trace or non-detectable levels, protecting both health and plumbing.
  • Space-Saving Alternative: Get the performance of a whole house water filtration system with a space-saving design and a lower cost compared to whole-house reverse osmosis systems.
  • Enhanced Functionality: Along with sulfate filtration, this system softens water by removing hard water minerals, making it ideal for homes, livestock farms, and light commercial uses.

Key Product Features:

  • Capacity & Sizing: Built to serve households of 1-8 people and 1-3 bathrooms. Effectively filters up to 1500 ppm of sulfates and 40 gpg of hardness.
  • Installation Made Easy: Delivered assembled with preloaded filter media. Includes DIY installation accessories and instructions.
  • Free Delivery: Available within the continental U.S.
  • Quality You Can Trust: Our tanks and control valves are made in the USA, using NSF 61 certified filter media and NSF certified valves.
  • Customer Support: When you need help, we’re here – available through live chat from 5 am to 10 pm PST every day, including weekends and holidays. Email support and contact forms are also answered 365 days a year. Call us at 1-877-788-8387 (9 am to 5 pm PST, Monday-Friday).

Product Questions & Answers

Have a sulfate question that hasn't been answered? Live chat with a RainDance specialist for a quick answer!
 

Q: How is the Sulfate Eater different from a standard water softener?
 		 A: The RainDance Sulfate Eater is specifically engineered for high well water sulfate applications and contains specialty filter resins engineered to remove sulfates and soften hard water when water passes through. Standard water softeners cannot filter sulfates.

Q: How does the Sulfate Eater remove sulfates?
 		 A: This system contains specialty filter resin engineered to trap sulfates when water passes through.

Q: How much will it reduce sulfates?
 		 A: The Sulfate Eater can effectively filter up to 1500ppm of sulfate and reduce the levels to below the EPA secondary maximum limit of 250ppm. In most cases sulfates are filtered down to trace or non-detectable levels.

Q: Does it soften hard water?
 		 A: Yes, the Sulfate Eater softens hard water up to 40gpg (or 684mg/L). Hard water softening is needed as excessive hard water can destroy the specialized media we use to remove sulfates. If you already have a water softener and would like to add the Sulfate Eater we can remove the softening option. Contact Us for additional information.

Q: Will it remove iron or sulfur odor?
 		 A: No, iron will foul the specialized sulfate media and must be filtered prior to the Sulfate Eater. If you have both iron and high sulfates Click Here for our Iron Max-Sulfate Eater Package

Q: Is this a reverse osmosis RO system?
 		 A: No, this system is an specialized ion exchange system similar to standard water softeners. Reverse osmosis systems use a specialized membrane designed to remove impurities and other contaminants from water. The Sulfate Eater is an affordable alternative to whole house RO systems which require multiple pieces of equipment.

Q: Do I need a plumber to install?
 		  A: If you are handy and have basic plumbing skills you should have no problem with this installation. The Sulfate Eater is installed exactly like a standard water softener. We provide detailed installation instructions, pictures, and offer several means of tech support for you or your plumber.

Q: How much maintenance is there?
 		 A: The RainDance Sulfate Eater is maintained the same way as a standard water softener. Simply add water softener crystals or pellets to the brine tank when needed. Softener pellets can easily be purchased at your local hardware store, some grocery stores, Wal-Mart's, etc...

Q: How long have you been selling the Sulfate Eater?
 		 A: The Sulfate Eater has been our best selling well water sulfate filter since 1998!

Q: Where can I buy the Sulfate Eater?
 		 A: The Sulfate Eater is purchased directly from RainDance Water Systems - we do not sell our products on Amazon or EBay
