Easy Install and excellent performance
Installation of my RO system underneath the sink went surprisingly well. This was a replacement system for another brand which had failed after a few years of operation. I preferred the sleeker design and compact nature of the Aquasana unit. My installation was nearly 100 percent complete but I had neglected to fully seat the tubing into the remineralizing tube and after a few minutes the unit began leaking badly. Fortunately mopping up the excess water and fully inserting the tube took only a few minutes after which full capability and excellent water were readily available.
