Product Questions & Answers

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

Q: How is the Iron Max Sulfate Eater different from a standard well water filter?
A: The RainDance Iron Max Sulfate Eater is specifically engineered for well water applications and contains specialty filter media & resins engineered to trap iron, manganese, sediment, hydrogen sulfide gas odors, high sulfates, and hard water when water passes through. Standard well water filters cannot treat these issues.

Q: How long have you been selling the  Iron Max Sulfate Eater?
A: The Iron Max Sulfate Eater has been our best selling multipurpose well water iron & sulfate removal system since 1998!

Q: Where can I buy the Iron Max Sulfate Eater?
A: The Iron Max Sulfate Eater is purchased directly from RainDance Water Systems - we do not sell our products on Amazon or EBay
Q: How much will it reduce sulfates? A: The Sulfate Eater can effectively filter up to 1500ppm of sulfates and reduce the levels to below the EPA recommended limit of 250ppm. In most cases sulfates are filtered down to trace or non-detectable levels.
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.

Q: How much will it reduce iron and manganese?
A: The Iron Max can effectively filter up to 12ppm of ferrous and ferric iron and up to 5ppm manganese and reduce the levels to below the EPA Secondary maximum limit (0.3ppm for iron and 0.05ppm for manganese). In most cases they are filtered down to trace or non-detectable levels.

Q: What kind of maintenance is required for this system?
A: The Iron Max is considered a maintenance-free system because it does not require any routine filter changes and there are no chemicals or salt to add. The Sulfate Eater is easily maintained by adding standard water softening pellets periodically to the brine tank.

Q: Do you offer any rebates or discounts?
A: Yes! You can find current rebate & discount codes at the top of this webpage - Rebates & discounts are subject to change without notice

Q: What does backwash flow rate mean?
A: The backwash flow rate is the flow rate required for effective backwashing of the system. Your well system will need to provide this flow rate for the duration of the backwash.

Q: How long does the filter last?
A: The entire system does not need to be replaced, just the filter media. This Iron Max media is designed to last up to 8-10 years, The Sulfate Eater media is designed to last 3-5 years depending on water chemistry and usage. When the media is spent you can simply remove the old media and load new media into your system for continued years of service.

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. We provide detailed installation instructions, pictures, and offer several means of tech support for you or your installer if needed.

Q: How do I know my filter is working?
A: There are (3) test bibs and a well water test kit included with the Iron Max-Sulfate Eater. These bibs are easily installed before and after the Iron Max-Sulfate Eater for on-site testing. We also offer lifetime testing for as long as you own the system (sulfate testing not included).

Q: Is the Iron Max-Sulfate Eater a whole house iron filter?
A: The Iron Max-Sulfate Eater can be used as a whole house well water filter, business, restaurant, agriculture, farm and livestock water treatment.
