Hoping there are some plumbing experts out there that can give me some advice. I'm thinking of replacing my Moen kitchen faucet soon. I expected there to be a large nut under the faucet holding it tight to the counter. I see this horseshoe type of thing there and am not sure how it is secured to the counter.I thought the small black circle was an allen but it doesn't seem to be. The rusty hole to the left of it I'm not sure what it is and the rusty one to the left of it is possibly for a flat screwdriver? This faucet is probably 20+ years old and if I can't get it out I may have to pull the double sink out which I really don't want to do. Anyone ever had any experience with this typy of thing?
