Had a home inspector ( Engineer) looking over my house , for a couple who wants to buy our home. We got talking about septic health. I mentioned I heard lint was not good for the leach fields as it could plug things up. But next he blew me away with something unexpected. Anyone who is getting Chemo treatments he said, should not use a septic system. That person using the system will completely wipe out all the good bacteria. Kills the system. I'll bet not one doctor has ever mentioned that, to any patients. How about once the system is pumped, where's that end up? LOL!
