Wife and i use all the tp we want. We too have a well and septic and i have it pumped ever 3 years and the pumper always tells me i could have probably doubled that. Its not tp that screws up your septic. Soap from laundry and anti bacterial soaps you use are a much bigger threat to your septic. Anyway it cost me a 150 bucks to have it pumped every 3 years thats less then a buck a week. Im not going to worry about how much tp it takes to clean my but for a buck a week and if i wasnt so paranoid and waited 5 or 6 years it would be closer to 50 cents a week. Id bet those baby wipes and garbage bags cost you near that. the septic pumper is a friend of mine and he told me that if your septic is sized right for your home theoretically it should never need to be pumped. I screwed up with mine and its why im paranoid. I put in a 2 bed house system to save some money. Stupid in hind sight. but i do have my clothes washer and kitchen sink going to a swamp drain. So i dont get grease and laundry soap in mine. Either way i know one thing. Im not counting tp squares unless s really does hit the fan. Parden me now. its time for the morning constitutional
