Steve, Gerald, y'all hit it out of the park. Un-threaded the head and found fine grains of sand nearly blocking the little screen. Cleaned it out and it works great. That sand may have been in the line all along, since the faucet worked that way from the day of install. We typically use a double water filter before entering the coach, so I'm not sure where I gathered the sand.
I did a fresh water dump and then refilled the fresh water to hopefully remove sediment. Thank you gentlemen!
