In addition to really being conscious of using very little toilet paper (we use the kind from Aldi which states "septic safe" on the package), don't forget to use a product like Rid-X once a month. We use something called Green Pig which comes in packets that dissolve in the bowl. I make a mental note to use this on the first of each month. (I'm pretty paranoid about the septic system since moving into our home that needed many renovations including new carpet in finished basement. Our septic tank backed-up all over less than 48 hours after the carpet was installed - when it comes to the septic, you can't be too careful!)
Don't flush it at all. Put a trash can, I line them with Wal-mart sacks, next to the toilet for the used toilet paper and then we empty daily.
We have always used Scott as well. We tried Charmin and had problems. Scott disintegrates faster and flushes down better.
Our septic system lasted 5+yrs longer by using tp used for campers/rv's. It's a bit more expensive but it immediately dissapears in contact with water. Can't go wrong with that!
Forget about your brand. We have always followed the 6 sheet rule. Tear off no more than 6 sheets fold neatly and use. Generally that is more than enough. Occasionally you will have to repeat. This still uses far less than wadding it up. The biggest thing you can do to prevent septic system problems is get rid of or do not use your garbage disposal. All matter going down the toilet is already digested and broken down. Water from the showers, sinks,etc. is just water. Compost of trash your food items, peels and waste!
Most plumbers will tell you not Charmin. Especially the ultra which has lotion. Also it depends on how many people are in your family. If you want to run a test. Try different kinds in a sink of water and see which won't dissolve. Toilet paper is like tissue. Puffs is easy on your face but doesn't absorb well.
Scot Tissue says "Safe for septic tanks" right on the package. We've used it for years without any problems. Stay away from products like Charmin. They are the worst for septic tanks.
