I have a kitchen faucet that is a Moen, a replacement for the old one I tossed about a year ago. Since then, the Moen isn't secured tightly, and it's bothered me enough to try to fix it.
I just don't know how to tighten it. Well, what tool to use. I certainly don't have it.
Thank you for your input.
Update: It's a very large nut and won't take a normal basin wrench. It's evident in the image, but people don't look at the image.
