Product Questions & Answers

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

Q: What does continuous filtration mean?
A: The Twin Sulfate Eater features two tanks for treating well water. Water is softened and filtered for sulfates in one tank while the other is in a standby mode. When the capacity of the first tank is reached, the system automatically switches tanks. The first tank is then recharged and remains in standby until the second tank reaches its capacity point. By using two alternating tanks there is always one tank filtering water at any time of day.
When a standard single-tank type sulfate filter is recharging, any water used during this time will be unfiltered and allows sulfates and hard water to get into your plumbing. Our twin-tank system is a great option if you have high water usage or use water at unpredictable times and need sulfate filtered water at any time of the day or night.

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 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 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 contact us for our packaged water treatment solution. The Sulfates Eater can reduce some odors, however hydrogen sulfide gas needs to be filtered with different technology. If you have hydrogen sulfide gas "rotten egg odor" contact us for the proper treatment method.

Q: Is this a reverse osmosis RO system?
A: No, this system is an 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 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

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