We had a leaky faucet in the bathroom and bought a replacement for it over a month ago.  Finally got around to installation and could not get the old drain out of the sink.  We called a plumber and the estimate I got today was $380.56.  Three hundred and eighty dollars???  That's absurd! Is there anyone out there who is handy with plumbing and good at working in tight spaces with no visibility?
