According to Areo-Stream records, we purchased our system in 2011. We were looking for a solution for our aging system, and ran across Areo-Stream. Our system is very old, tank and 2 drywall, probably put in the 70's or before. We were pumping every month or more than that, close to being forced into mound system, that would have taken up most of our backyard, since it's a 2 unit home. To our luck, Areo-Stream said us...wasn't over night, but after installing the system, pumping was less and less, a noticeable difference in a year, and just got better as time went on. We needed 2 parts, through the years, minimal cost, excellent customer service! Fast forward to 2025, needed another part, minimal cost. We needed our 3 year State inspection, so needed pump, but we haven't had it pumped for 3 years, no ponding, no smell, running smooth! Passed inspection with flying colors! Thank you so much! Highly recommend to anyone needing to solve their septic problems!
