@Pete28 This ties in with the "Do you fix things yourself?" thread. I realize many people are not at all mechanically inclined and may be totally intimidated by the simplest of repair or maintenance jobs, but often I've found that it's just a matter of them assuming it's far more complicated than it actually is, or that one needs special training or a plethora of specialized tools. Some people may not even have a clue what a hex key is. Youtube videos are extensive and great for learning how to troubleshoot and fix things.
While staying with a friend in Denver, I mentioned to her that I had noticed that all her faucets dripped (a no-no in drought-prone Denver in the summer) and her reply was that yes, she knew, but she'd been procrastinating because it cost like $300 just to get a plumber to walk in the door. I told her they just needed new rubber washers and that I could easily do that for her. She looked really skeptical, but I assured her I'd done it many times, it was hardly rocket science, nor an all day project, and something all homeowners should really learn how to do. We went to the hardware store and bought a package of washers and I replaced them all. She saved all that $ on a plumber and took me out for dinner 🙂
