Before You Change that Next Faucet, Pick up a Basin Wrench
Unless you've done something more than the simplest of plumbing jobs, you probably still grumble about how much a plumber's time is worth, at least according to their bills. If, however, your "vast" experience goes beyond installing a new valve or flapper in your toilet tank or replacing a leaky faucet washer, you may know better. Once you get beyond the jobs you can complete standing up, you start to appreciate the skill of trained plumbers; perhaps even more so a trained plumber's collection of tools.
