A few days ago my 5 year old told me the toilet wouldn't flush, I didn't think anything of it until later that night i heard running water and saw that a part was broken. I wasn't sure what it was so i looked up a diagram on google found the name for the part i needed. My wife went a few days ago to get the part I needed since she was already in town getting groceries but i mistakenly told her the wrong size so we had to deal with fixing the flapper seal for a few days until we had a few other things to get in town. I was able to pick up the part today and install it. Lesson learned if you can bring the old/broken part with you to the store it makes finding the replacement part a lot easier.
