In Oct of 2009 I contacted Aero-Stream after having my septic system pumped 4 times over the last 3 years. Everyone who came out only wanted to replace my drain field. I installed the system in about 1.5 hrs. It was very easy to install. It ran for 8 months but did not resolve my problem. Tech support was fantastic, every time I called they provided new ideas. Unfortunately my problem turned out to be a clog just past the d-box. I contacted Don at Aero-Stream and he promptly arranged a refund of my full purchase price. I returned the unit and received a check about 10 days later. I recommend them to everyone I know who might have any issue as customer service and warranty is true to the test. Feel free to email me if you wish...houseman123@yahoo.com
