Kitchen sink faucet - putty or silicone, and where?

I'm trying to install a Moen Anabelle kitchen faucet (stainless steel spit resistant model) in a 4-hole stainless steel sink.



This is what I've done up to this point:

  • Removed all supply lines
  • Removed old Pfister faucet and sprayer
  • Removed rust / corrosion from top of sink with Lime Away

I'm ready to install this Moen faucet, but the instructions are IKEA-grade (photos, no details) and do not describe the preferred means of sealing the deck plate to the sink.

Please look at the photo below -- which piece(s) should have putty or silicone on them?

Fair enough.

However, if the gasket is optional, is Moen assuming I'll use silicone or plumber's putty underneath the deck plate?

I want to make sure I do everything I can to mitigate leaks, with the understanding that there's a lot of parts internally to this faucet that would result in leaks well beyond the deck plate.

Thanks,

I think I'm going to do what some else suggested and just put a ring of plumber's putty around the other two deck holes. Just seems really unstable to ONLY be fastened to the sink with the middle deck hole for such a tall faucet.

I'm also going to call Moen in the morning to ask WHY the gasket is optional AND what would void the warranty.

I like this idea. Gonna look at it after dinner.

My concern is that the deck plate is ONLY secured by the center deck hole. There are no fasteners to secure the sides of the deck plate through the left and right holes. With a faucet this tall, I worry about it lifting the sides of the deckplate off the sink and splashed water getting up under the gasket on the lifted sides.
