How to Connect PVC Drain Pipe to a Cast Iron Hub · Step 1 of 7
In this video
Before starting, ensure you are wearing the proper personal protective equipment (PPE). In the video, the user is wearing safety glasses, hearing protection, and gloves. Place the galvanized pipe securely on a sawhorse to keep it stable during the cutting process. This setup ensures both safety and accuracy for the task.
Goal: Set up the work area and wear PPE
- Failing to secure the workpiece can lead to it vibrating or moving during the cut, which is dangerous and can result in a poor-quality cut.
Used in this video

FAQs
Why is a cold chisel listed as a required tool, and how is it used in this project?
A cold chisel, specifically the Dasco Pro 3/4 in. x 12 in. Cold Chisel G410, is essential for carefully excavating the old lead and oakum seal from inside the cast iron hub. It allows you to break apart and remove the old, brittle material without damaging the cast iron itself. Use it with a hammer, chipping away small pieces at a time to ensure a clean interior for the new seal.
What are the most critical safety precautions I should take when connecting PVC to old cast iron pipes?
Always wear safety glasses (like the listed Safety Glasses) to protect your eyes from flying debris, especially when chiseling old material or dealing with rust. Use heavy-duty work gloves (e.g., Husky Large Premium Grain Cowhide Leather Heavy Duty Impact Work Glove) to protect your hands from sharp edges, rust, and potential contaminants. Ensure good ventilation, as old drain pipes can contain unpleasant odors and bacteria.
How long does this project typically take for a beginner, and what's the approximate cost?
For a beginner, this project generally takes 2-4 hours, depending on the condition of the old seal and your comfort level with the tools. The primary cost will be the PVC pipe and fittings, the rubber compression gasket (donut), and a few specialized tools like the cold chisel, totaling roughly $30-$70 if you don't own the tools already. These costs can vary based on local prices and specific product brands.
What's the most common mistake DIYers make when installing the rubber compression gasket, and how can I avoid leaks?
The most common mistake is not thoroughly cleaning the inside of the cast iron hub, which prevents a proper, watertight seal. Ensure the hub is free of all old debris, rust, and scale using a wire brush. Additionally, apply a generous amount of plumber's grease (Oatey 1 oz. Plumber's Grease 30620) to both the gasket and the PVC pipe end to help it slide in smoothly and create a tight seal.
