A cast iron pipe is the main pipe flowing from your home or drain line direct building to the main sewer line. The old cast iron pipes corrode over time, rusting and rotting. Leaks can start as small holes and become more problematic over time. You can patch these holes, but be aware that corrosion is likely to be present in several places in your pipe. Consider to repair until you can replace the entire line.
- When working with epoxy, Put on rubber gloves to protect your skin from irritation.
- Search the vanishing point. You may need to spend a dry towel along the barrel, drying. Then wait until bubbles appear in the area of the leak. Circle leaks with an ink pen.
- Mix epoxy putty according to the instructions of the manufacturer’s label. You may have to mix one part of the mastic with five parts water to get exact pasty to place over the leak.
- Crush with your hands putty about leaks when necessary to form a thinner layer.
- Enables tape epoxy resin according to the instructions of the manufacturer’s label. Some tape before wrapping it wetting required curing the resin during drying.
- Wrap the area where you marked leakage. Start with the tape at least 1 inch (2.5 cm) above the drain and wrap the pipe down on the run. Roll a layer so that leakage exceeds at least 1 inch (2.5 cm) and then returns to the area of the leak by wrapping several layers more, creating a thick central portion of the leak.
- Let the tape epoxy resin is cured for 30 minutes or the time required according to the manufacturer’s label.
