We purchased an aero-stream in June of 2013 because we had issues of water coming up to the surface because it was no longer draining through the leach bed. We were faced with the real possibility of having to have an entire new leach bed built costing in the 10's of thousands of dollars. Fortunately I came across the aero-stream one night as I was doing some research on line and read all about what this little unit claimed that it would accomplish. The old saying that if it sounds to good to be true it probably is certainly did apply here. But at the same time faced with the reality of having to spend 10's of thousands was not something I wanted to do either. Besides they were only asking 1500.00 Well it turned out to literally be one of the best purchases. Within 1 month the biomat that had formed which was preventing the water to drain properly through the leach had dissipated and we had no more water on the surface. The pump also ran 24/7 365 for 6years straight before it stopped. I called aero-stream they told me to ship it in our bring it in which is what I did and in about a week it was fixed and shipped back to me. We are up and running again. Awesome awesome product. Thank you aero-stream!!!
