Product Questions & Answers

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

Q: How is the Iron Max different from a standard water filter?
A: The RainDance Iron Max is specifically engineered for well water applications and contains specialty filter media engineered to trap iron, manganese, sediment, and hydrogen sulfide gas odors when water passes through. Standard water filters cannot handle the "BIG 4" which are high iron, manganese, sediment and hydrogen sulfide gas odors.   

Q: How long have you been selling the  Iron Max?
A: The Iron Max has been our best selling well water iron filter for whole house, commercial business, and irrigation water since 1999!

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

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. This system uses automatic backwashing to clean the filter media which also prevents low pressure and low flow problems.

Q: Will this system discharge any harmful chemicals in my septic system?
A: This system does not use any chemicals like potassium permangenate or chlorine for regenerating so this system is safe to use with septic systems. In most cases the drain water can actually be reused in other areas like irrigation.

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 media is designed to last up to 8-10 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. The Iron Max only requires 3 simple connections - inlet, outlet, and drain line. 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 (2) test bibs and a well water test kit included with the Iron Max. These bibs are easily installed before and after the Iron Max for on-site testing. We also offer lifetime testing for as long as you own the system.

Q: Is the Iron Max a whole house iron filter?
A: The Iron Max can be used as a whole house well water filter, irrigation & lawn water filtration, commercial business, restaurant, agriculture, farm and livestock water treatment. This system can be used virtually anywhere where iron filtration is needed.  
Q: Can I reuse the Iron Max backwash drain water?  A: Yes, we are often asked to comment on the waste of backwash and rinse water from our Iron Max well water filters. Actually there is no wasted water in the classic sense. The Iron Max iron filter does not add any chemicals to the water so the water going to drain has pretty much the same chemistry as the source water. Some constituents such as iron and manganese are in higher concentrations, but the water is still usable. With rare exceptions this water (we prefer the term discharge water vs. waste water) is suitable for irrigation use where the content of iron or manganese does not affect the plants or it can be discharged into a dry well for eventual percolation into the original aquifer. With a little planning, the Iron Max can be installed without a drop of water ultimately being wasted!
