I caught your show while driving this morning and heard a caller mention bakers yeast. You mentioned putting in a toilet once a month. I believe this is for a spetic system, and does this eliminate the need for having a tank pumped out every three years? I missed the original call whenever it was.
Answer:
It certrainly is for a septic system and all id does is keep bacterial action going. I don't see a need though for pumping the tank every three years. Properly looked after, the tank shouldn't have to pumped any more often than every ten years or so.
