​​The RainDance Water Systems Twin Tannin Eater-12 Twin Alternating High Tannin Removal and Hard Well Water Softener:​
  • Premium Water Treatment - Premium Services!
  • Why you should consider a Twin Tannin Eater: Single-tank systems can’t backwash and soften & filter your water at the same time, so there may be times that untreated tannins & hard water flows into the plumbing. Our twin tank system, such as the Twin Tannin Eater offered by RainDance Water Systems, don’t suffer from this problem.  NO Down Time! They keep filtering high tannins & softening your well water 24 hours a day, seven days a week.
  • Softens Hard Water Up To 40gpg & Filters High Tannin Up To 5ppm
  • Free lifelong water testing to maintain optimum performance.​​ ​
  • ​Ships pre-loaded with media for hassle-free, quick & easy installation!
  • New Upgrades Included:
  • NSF 61 Certified Water Treatment Media - Yes
  • NSF Certified Control Valve & Tank - Yes

​Tannins: Tannins (humic acid) are found in waters which have passed through large quantities of decaying vegetation. Tannins can cause yellow water and yellow staining on fabrics and fixtures. Tannins measuring at the low level of 0.5ppm can be problematic as tannins dissolve permanently into the water and won’t settle out over time. This can create a bad taste and odor in the water and cause staining to washing, toilet bowls, bath tubs and wash basins and cause poor filtration performance in water treatment systems. Read more on how the RainDance Tannin Eater can remove both tannins and soften hard well water below.

The Twin Alternating Tannin Eater is used where there is a demand for tannin filtration and hard water softening at flow rates or capacities higher than those obtainable through a single water system. 

The Twin Tannin Eater alternating twin tanks provide an uninterrupted supply of tannin filtration and soft water to your home or business. The Twin Alternating Tannin Eater has two tanks for softening and filtering. Water is softened and 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 recharged. This cycle is repeated when the second tank reaches its capacity point.
