I'm writing this review after installing our Aero-Stream system FOUR years ago. In the summer of 2013 we had water seeping up through drain field. Not a good thing. Knowing the exorbitant costs of replacing the drain field I started looking on line to see if there were any other options. That's when I came across the Aero-Stream website. I studied it extensively and what really helped sell me on the system were all the reviews past customers had written. And the reviews were from all over the country! I still had my reservations if the system would work but after installing in September of 2013, it has worked flawlessly. The seepage coming up from the drain field disappeared and the water levels in all four lines is minimal. I had some questions during installation on a Friday evening and Aero-Stream answered my call and questions instantly. Most recently I sent the pump in to be refurbished and they turned it around in one day. Amazing customer service! We saved thousands of dollars with the Aero-Stream system. Thanks Aero-Stream!
