What to Do If You Still Have Cast Iron Piping

Cast iron pipes are durable but can deteriorate over time, especially in older homes. Corrosion, rust, and shifting foundations can lead to leaks, reduced water pressure, and sewer gas risks. Knowing what to look for helps you assess urgency and choose a safe, cost-effective path forward.

What you’re likely facing

Common signs include unexplained water stains, gurgling sounds, slow drains, and sudden drops in water pressure. In basements or crawl spaces, you may notice wet spots or rust around joints. If you see cracks, leaks, or rodent-chewed sections, these are red flags that require professional inspection.
