Learned about Aero-Stream due to luck
During one of my required 3-year tank pumping intervals, beginning January 1979, I found my tank was filled above its output tile. I told the pumper guy "I'm going to dig/expose the distribution box so I can see what's going on." I found that the D-Box had collapsed. I ultimately dug out the rubble and built a new concrete box. During that interim, I was in Menards and noticed foldouts in a little rack regarding Aero-Stream Septic System Saver. I purchased one. I also ordered a 50-foot Clog-Hog hose to attach to my pressure washer for cleaning the distribution tiles. The Saver has been in service now 24-hours per day for over 3-years. I made a dip stick so I can check the water level in the D-Box. The water level has remained consistent since the day of completing the rebuild. The pump rests out side near my garage and purrs like a kitten. In Minnesota that's saying something in itself.
