Ok so here is a trick my incle a plumber told my mom and ahe told me. When at a peraons house always flush it before you use it. If the toliet is going to over flow it will do it with or with out you using it.
Here is a good example:
Me and my Husband met online. And when we finally met in person I was going to stay with him for 1 week to see if we like each other. Well the first time I uswd thier bathroom I did this trick. I didnt even use it yet and fluahex it before hand. AND IT OVER FLOWED! So THANK GOD I did this because I just met him and his family. Inmagine if I went potty and they had ro fix it. Lol
