Changed the seats and spring in my mother’s Delta kitchen faucet today, thanks to this clear video from YouTube user funbro1 aka How To Bob.
Removing the handles took much longer than actually replacing the seats and springs as they were corroded on and prying them off came too close to mangling them for my liking. Bob put silicone grease on some of the parts during reassembly to help the handles turn more easily, which I had never thought of doing. I didn’t have any silicone grease, but do have a 20-lifetimes supply of food-grade bearing grease purchased a couple of years ago to repair an old hand mixer. I dabbed some on the set screws, nuts and handles to make it all easier to take apart for future repairs.
