I own a small rental house, and it has an especially small septic system because it was built as a vacation home. From the inspection I had when I bought it, the tank has no baffle inside and the drain "field" is only a single 75' line. The septic guy recommended increasing the size but we decided to wait and see - after 2 years of 2 people living there it is still working fine. I'm wondering if I got an air pump and installed an air bubbler into the existing septic tank, would that help make everything in the tank break down faster? Would this be a better potential first option rather than possibly putting in a larger drain field and tank? Is it that simple to convert an "anaerobic system" to an "aerobic system"? Google seems to say this will work but all the websites I find want to sell me the system, so I don't trust them much. I do have space to increase the size of the system, but would rather not do that if I don't have to. Even if it needs to be pumped every 2-3 years that isn't that bad.

Say, I'm having a similar issue and question. Please let me know if I should create a new thread. When the ON float comes on, the control panel runs one of the pumps (2 pump 3 float system) and when the level reaches the OFF float, the pump will sometimes turn off normally. Unfortunately, most of the time it short cycles on and off for about 10 seconds very rapidly before finally staying off. I purchased a new float thinking it was the off float but have yet to install it. Based on your comments above, it sounds like this may be the ON float not recognizing it is hanging and keeping the pumps off. The distance between the ON and OFF float was very minimal so I moved the ON float up 2 inches to make sure it has enough time to know it should be OFF, but the same thing is occurring. I guess I should just replace both floats, but I was curious in what order they communicate with the relay/control panel.
