I just installed a Glacier Bay bathroom faucet, and while the faucet portion works fine, the supplied drain is slow. Water takes a couple of minutes to drain from a half-full bathroom sink.
At first I thought the plunger was not being lifted out far enough, but lifting it with my fingers seemed to have little effect. The pivot arm below the sink (the one that screws into the drain iteself, sorry don't know correct term) seems to be traveling the full range of motion.
Any ideas?
