OK... thanks for the help everyone. I'm still having a really hard time finding the correct reducers and connectors to fit my aspirator to the faucet though. I've been to so many stores and none of them had the right thing. I think I'm gonna have to retrofit it with some tubing and put it on my other sink which is way more forceful anyway, but it has no threading. Stonium, I would love to make you happy, but I cannot edit my first post anymore.
