septic tank & ?additives... good or bad?
My nephew lives alone on 5 acres & had a new septic tank system installed 10 years ago. It overflowed this fall & the cleanout company said it should be emptied every 8-10 years. I have been giving him my outdated packs of yeast to flush down a toilet but this sewer guy said NOTHING should be added/put in the septic tank as it causes problems. I thought the bacteria/yeast would help in the digestion process but this guy said no. Any thoughts on this or is this guy wanting to have to clean out septic tanks every 8-10 years?
