I agree with most post, Some systems can go long times between pumpings some cannot. On my system I have seperate systems for kitchen and clothes washer. I have been in this house about 15 years and have never had to have it pumped. I have it checked about every 4 years by a neighbor in the business and have not had enough build up to require pumping. I use some of the bio material about every 2-3 months but not sure it's really needed.
