As part of our kitchen remodel we are having a pot filler installed. I took it out of the box the other night to check it out and when it started to unfold there was quite a bit of crunching noise in the hinge. It worked loose and then something started rolling around inside one of the arms. I got the cartridge retention nut tool today and pulled the cart and out popped what looks like a little broken piece of ceramic rod. I am waiting for Moen to call me back but figured I would post some pics here to see if you all have any idea what this is...from a broken part to something that fell in during manufacture. I cannot find anything in the exploded diagram that looks like this unless the cartridges have ceramic inside them.
