Product Questions & Answers

Have a 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-RDWS-NS features two tanks for treating well water. Water is filtered 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 backwashed 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 single-tank sediment filter is backwashing, any water used during this time will be unfiltered and allows sedimet to get into your plumbing. A twin-tank system is a great option if you have high water usage or use water at unpredictable times and need filtered water at any time of the day or night.

Q: How does the RDWS-NS remove sediment?
A: This system contains specialty filter media engineered to trap sediment, sand, and particles when water passes through. This media provides superior water filtration performance and solids loading capacity compared to conventional multi-media water filtration media due to its unique structure, allowing particles to penetrate deep into the filter bed to provide greater filtration at higher flow rates.

Q: How much will it reduce sediment?
A: The RDWS-NS series can effectively filter sediment, dirt, debris, and particles in the water as fine as 3-5 microns.

Q: What kind of maintenance is required for this system?
A: The RDWS-NS series is an automatic self-cleaning "no-maintenance" sediment filtration system. Unlike conventional in-line cartridges that require frequent replacement, these systems use long-lasting filtration media that provides ultimate filtration for years of filtration performance.

Q: Does this system have waste water?
A: Yes, this system uses water to rinse the filter media of built-up sediment and flushes out through the drain line. This drain water contains no harmful additives so the drain water can actually be reused for a no-waste system.

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 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. The RDWS-NS system 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 water test kit included with the RDWS-NS system. These bibs are easily installed before and after the system for on-site testing. We also offer lifetime testing for as long as you own the system.
