I was at the end of my rope facing a $20,000 engineered septic field when I found Aero-stream product on line. We had a sluggish field with gurgling noises when using shower or doing laundry. The no risk offer combined with product specialist assuring me it will work convinced me to make the investment. The gurgle noise stopped immediately with no problems for 6 months until the snow melt came. The gurgle came back and I requested my money back. The product specialist Dave said it take time to rejuvenate a field and extended my warranty and sold be a jumper kit which included a container of powder. We got through the melt season here in Michigan in 2015. This year melt had no issue with gurgle noise. At this point I am hopeful that enough time has passed that we will have no additional gurgle noise and my filed is on its way to total recovery. Aerostream you not only saved the day you save me over $25,000 after landscape costs.
