DIY: How to Replace a Faucet
- 1). Turn off the water to the faucet at the nearest shut-off valves. For a kitchen or bathroom sink, they will likely be under the sink. If there aren't accessible shut-off valves, turn off the water to the house where the main water line runs in.
- 2). Unscrew the local water lines where they meet the faucet stems under the sink. Loosen the mounting nuts that secure the faucet to the sink with a wrench. In most cases, the nuts are directly below the faucet assembly. Lift the old faucet assembly away from the sink.
- 3). Clean off any residual dried caulk from around the holes where the faucet assembly was located. Set the new faucet in place, guiding the faucet handles' threaded stems through the holes and under the sink. Slip the provided washers and mounting nuts over the stems and tighten them up against the underside of the sink. Slide the faucet so that it's even with the back wall, then tighten the mounting nuts underneath the sink with your wrench.
- 4). Wrap a small length of plumber's tape around the bottom of the exposed stem, wrapping in a clockwise direction. Connect the water supply lines to the ends of the stems and tighten snugly (clockwise) with your wrench. Don't over-tighten.
- 5). Turn on the water and watch under the sink for signs of leakage. If any water appears, turn the supply off again and tighten the water lines where they meet the stems. Once the seal is tight, run a thin bead of clear silicone caulk around the base of each of the faucet handles and the spigot on top of the sink.
