Love your Hexagon Alkaline Hydrogen Rich Structured Water, but don't have space on top of the counter. 

No problem... Coming Soon - a valve to allow you to install it conveniently under the sink.

Watch how.  This video is LONG and relatively boring, but if you are really putting it under the sink you should find it helpful.  It was done more to document the process as I was selected to be one of the first to test it out here in the US.

I will probably try to recreate with better edits, more graceful disassembly and such, but this is better than nothing for now.
