The handle on our Moen 4570 bathroom faucet had been getting progressively looser over the course of a few weeks. I ignored it for as long as I could, but then it finally fell off. Time for a repair. Here's a video of my Moen 4570 handle removal and the simple replacement of the screw that came loose. Pretty simple fix you just need a screwdriver and a pair of needle nose pliers. Since posting this video originally I’ve heard from folks that the same repair works with other Moen and some Kohler models, including the Moen T6620.

If you find that this fix works for your faucet, please comment below with the model number so I can add it to the list and make this video more easily findable. Thanks!
