Step 1 · Prepare the Work Area and Ensure Safety

Begin by ensuring no water will flow through the drain pipe during the repair. Inform everyone in the house not to use any sinks, showers, or flush any toilets. Clear the workspace directly below the damaged pipe section. Lay down heavy-duty plastic sheeting to catch dust, debris, and any residual water. Gather all your tools and materials and place them within easy reach. Most importantly, put on your safety equipment: safety glasses, heavy-duty work gloves, and a respirator to protect against cast iron dust.
