Thanks for all the replies and advice. Y'all were right. The aerator was a bit of an SOB to remove, but once it was off, I found the aerator full of sand (suspiciously similar to the sand at the beach campground where we last stayed). I'm confident I didn't drag the water hose through the sand, so I'm thinking they have some sand in their water lines. There was a small amount of sand in the Oxygenics shower head as well. I guess its time to invest in an in-line water filter.

An additional question...any insight into how to safely/easily remove the aerator on the kitchen faucet (2nd picture)? The water flow seems ok, but I'd like to make sure its clear.

Thanks Again!
