CC,

I think my parents pumped their old system once in about 30 years but I think the new systems are designed differently. Sounds like my setup is similar to yours. My septic guy said 4 years between pump outs. I think a lot depends on the size of your tanks and number of people in the house. The filter between the tanks could turn into a real PITA if you forget to clean it. It will block the flow to the second tank/field and the liquid from the top of the solids tank will overflow out the green plastic filter chamber. (Don't ask me how I know that! frown ) The tank additives I've seen are pretty pricey IMO to use every month. My septic guy said that flushing toilet bowl cleaner kills the bacteria/yeast you add in a while anyway. (Imagine that. Anti-bacterial bowl cleaner killing bacteria! smile ) My advice, pump the solids tank every few years. The other tank probably won't need it near that often.
