I 'm so glad I invested in Aero-Stream. It was so affordable and the product worked. It was easy to assemble and it relieved me of so much stress. We had tried everything except a system overhaul, and that was very expensive. The service was great, and within days the smell disappeared. I must confirm that you must give the product time to work on the drain field. We did and our drain field is looking good. I'm very happy with the results. The service I received was just a blessing, they were very patient and understanding. I'm a happy customer.
