Many thanks to Hodorskib and others for sharing their experience with small scale RO builds. Last year I used the RO Bucket (RB-10) with Aquatech 8855 and 2x400 gpd membranes in parallel with pretty good results overall. This year I decided to disassemble the Bucket and mount it to a board to ease access to the RO components. I often found myself chasing a small air leak in the tubing connections and had difficulty getting to the tubing connections to ensure they were fully seated. I'm hoping that the board mount will provide easier locating and fixing of leaks, or, even more so, I'm hoping I'll be able to assemble the tubing connections properly to prevent leaks. I also will add a another membrane to make it a 3x400 gpd kit and plumb it in series like the Hodorskib Build.

Hodorskib: I recall you indicated in a posting quite a ways back that you had planned to share the results of the 3 x 400 gpd system. I've searched these postings and your website but could not find it. I'm curious how the 3 x 400 gpd system performed compared to the 6 x 150 gpd.
