God works in mysterious ways. It's a fact. We went through some toilet trouble a short time back. We got the toilets fixed, and learned a lot about our septic lines. A couple times since last week, the toilets have backed up. No, it's not a problem with the septic system. It's a problem with a 3 year old in potty training, learning to use the correct amount of toilet paper. Due to the earlier issues, the cap to the drain line is easy to get off. The pipe is the exact size that the plunger fits over it, and a little plunging clears out the excess toilet paper in the line, so it drains on into the septic tank. Viola! Within minutes, it's good to go. Now, back to convincing the 3 year old that 1/2 a roll of paper is too much.
