I have this Kohler kitchen faucet (K-15160 (http://www.us.kohler.com/onlinecatalog/pdf/1108714_2.pdf)) and by mistake, I unscrewed the "spray" head (part 1109445) from the "insert" (part 1000194) that's inside the "hub" (part 1003735).

As soon as I unscrewed the spray head, the "insert" snapped back into the "hub", and now I do not know how to pull out the "insert" to be able to screw it back.

Does anybody have any experience with this?

Much thanks..
