Terrific experience over the years
We had an ancient and gigantic rock cesspool to service our 1908 house on 1/10th of an acre--a disaster waiting to happen. Yet the Aero-Stream aerator worked so well that for 6 years we had no issues. The guys who periodically pumped our tank marveled at the lack of sludge and odor. When the motor finally burned out after several years, Dave D who was our original contact at the company promptly sent out another at a reduced price as we sent back the old one to be refurbished. That one has continued to work 24/7. Great concept, execution and service, at super-reasonable prices, especially considering what would have been the alternatives.
