Cruzmisl,
I'm pretty sure 16" is NOT enough as you will need to put the flow switch in-line as well. I'm not positive from the picture but it looks like you have 1.5" piping. If that is the case you will need to add reducers into the equation as the turbocell and flow switch are 2". When I did my Aqualogic install, I believe my calculation for all components including reducers and only leaving 0.25" in between each component was 28.75" total space needed. Unfortunately, I see a snake in your future. Hope this helps.
Regards,
Mark
