Last Saturday I heard that faint running water sound in my bathroom at like 11pm. I figured it was the flapper again so I spent an hour taking the whole thing apart and replacing parts. Then I noticed the handle was wiggly so I tightened the nut behind it with a wrench. Water stopped instantly. Total time wasted was over 2 hours for something that took 30 seconds to fix. Has anyone else ever gone down a rabbit hole on a simple fix like this?
