Shower/tub faucets, those that service both a tub and a shower head, come in 1-, 2- or 3-handle configurations. Of all of them, the 3-handle configuration is probably the most common, and is relatively easy to repair. In preparation for the repair, I lent John one my library’s most popular books, Black & Decker’s Complete Guide to Home Plumbing. It contains the exact procedure that John would be performing, minus some key information that may be important to a newcomer. [ . . . ]
