I have 2 identical moen chateau faucets in my main bathroom, someone (kids, eh?) took the aerator off one of the sinks and it will not screw back in. From what I can see they should all be 15/16" and seem to be universal. Took the one from the bad faucet and it screws in the other faucet with no issues. Am I missing something? Looking at having to replace the faucet because of the aerator?
