This house is 50 years old, but the upstairs bathroom is considerably
newer--probably 8-10 years. Within the last week pressure to the
sink has dropped to almost nothing, both hot and cold. Thinking it
might be some sort of obstruction in the supply lines or faucet, I
replaced both, but no dice. The pressure in the adjacent toilet and
shower is fine. Any ideas?



Unscrew the "aerator" on the spout and clean the screen.
More than likely a clump of "gunk" (technical term)
got deposited there. Could have come from the older
piping in the house or even from the Mains outside.

Thanks for the quick response. Faucet (and aerator) is brand-spankin' new.

Well, it *was* the aerator. After I thought about it for a minute, it
seem to be the only possible answer. The aerator was clogged with a bit
of some sort of metallic debris. Being that the new faucet got clogged
almost as soon as I turned it on, I removed the aerator and just let the
water run for a while to see what else might show up. Then I went in the
basement and looked at all of the water pipes I could see, and
discovered a galvanized pipe with a pinhole-sized corrosion leak, which
might well have been the source of the problem. Thanks to Speedy Jim for
the answer.
