Speaking of septic tanks

[daytonacane]

I put in the toilet a package of yeast (instead of RidX) once a month. My son own his own plumbing company and he put in a new drain field 22 years ago and I have never had any problem. My tank is in the front yard and I live on a hill; thus, when it rains I am never flooded.

I'm on a peninsula of a lake. I'm really surprised I don't have any problems even in monsoon season. Of course I've probably just jinxed myself.
