Forgive my moment of patting myself on the back. Last night I found that the fill valve in the toilet on the main floor of our house needed to be replaced. I am not experienced with home repairs and in the past managed to mangle toilet repair enough to call in a professional to fix the job. So, in normal circumstances I would have just scheduled a plumber to repair, but I decided to search for information, found videos on YouTube that showed me what to do, and today I bought the parts and made the replacement as easily as was shown in the video.
