This past weekend I re-routed some fresh-water copper pipes under my house as part of a bathroom remodel project (both hot and cold pipes). After completing my work, I am noticing a significant water pressure reduction at my kitchen sink (all the other water outlets throughout the house have the expected pressure). It just so happens that the faucet in question is the first outlet I tried after returning the water service to the house. I'm wondering if something got in the line during my work (dirt, copper filings, etc) that immediately clogged this faucet the first time I tried it? Both hot and cold water are affected, so I removed the aerater to look for a clog, but it was lean. I suspect the clog might be at the valves. Thoughts?
