How do I tighten the handle of a Water Ridge NSF61/9 kitchen faucet.

Does the handle have a pop-off insert on top or a Allen Head screw in the bottom? Back to you, Tom

Unfortunately, the NSF61/9 tells us nothing...that's a national standard number that applies to most faucets nowadays. If there is no obvious cap to remove (or hole) then we need a picture of the faucet or a model number...UGH!
