Step 1 · Shut Off Water and Prepare Workspace

Begin by clearing the area under the sink to access the water supply lines. Locate the two shutoff valves, one for hot and one for cold, on the wall or floor. Turn the oval or round handles clockwise until they stop moving to shut off the water. Next, turn both faucet handles to the 'on' position to drain any residual water and relieve pressure in the lines. This confirms that the water is successfully shut off. Finally, place a thick towel or rag over the sink basin, making sure to cover the drain opening completely. This will protect the sink's finish from dropped tools and prevent any small parts from being lost down the drain.
