Step 1 · Plan and Gather Materials
The first and most critical step is to prepare your work area and ensure the water is completely off. Locate the main water shutoff valve for your home, which is typically found where the water service pipe enters the house, often in a basement, crawlspace, or utility closet. Turn the valve clockwise until it is fully closed. Next, relieve the pressure and drain the water from the system by opening the faucets at the highest point (e.g., an upstairs bathroom sink) and the lowest point (e.g., a basement slop sink or outdoor hose bibb) in your home. Allow the water to drain completely. Place a bucket directly under the section of galvanized pipe you will be replacing to catch any residual water that will spill out during the cutting process. Finally, gather and lay out all your tools and materials so they are within easy reach.
