Before replacing the washer, Richard performs a little surgery on the protruding edge into which the washer fits. He files away the pitted wall and replaces it with a nickel/copper-alloy retainer bowl, which will be held in place by a new washer screw. "Sometimes it's better to rebuild the stem than to rush out for a new part," he says. "Replacement parts for older faucets can be hard to find."
