Never Get Caught Out with Spent Resin Again!

With a twin-tank DI setup, you’ll always have a backup. Keep using Tank 1 until it stops lowering the TDS—don’t throw it out just because it reaches 20ppm. It’s still removing most of the impurities and sending partially purified water to Tank 2 to finish the job.

When Tank 1 is spent:

• Swap Tank 2 into the first position.
• Refill Tank 2 with fresh resin and place it second in line.

This leapfrogging method maximises resin usage and effectively doubles the filtration depth, outperforming smaller, single-tank systems.

Key Features:

• No tools needed – resin changes take just 10 minutes
• Includes sediment and carbon pre-filters
• Now includes a Buddy Box + Handheld TDS Meter – check tap water, between tanks, and final output with ease
• Requires 38L of DI resin (resin not included)

Note: The videos below are from earlier versions of this system, but many components remain the same.

Please refer to the product images and description for the latest design.
The current Twin Tank setup no longer includes built-in TDS or flow meters.

Updated videos are in the works.
