Living in one of Morristown’s historic homes? If your drains are slow no matter how many times you snake them, you aren’t dealing with a simple clog. You are fighting the pipes themselves.
Older cast iron pipes eventually develop a jagged layer of rust and mineral buildup known as scaling. This buildup narrows your pipes and catches debris. But here is the good news: you probably don’t need to replace them.
Pipe descaling is a restoration technique that scours away decades of rust, restoring your original flow without digging up your yard.
Why Old Cast Iron Pipes Fail

Why do drains in older homes back up even when you haven’t flushed anything unusual? It comes down to the aging plumbing infrastructure common in Morris County:
- The “Clogged Artery” Effect: Cast iron naturally rusts from the inside out. This creates blister-like bumps (tubercles) that shrink the pipe’s diameter. Just like cholesterol in an artery, this slows drainage to a crawl.
- Rough Surfaces Trap Debris: Modern PVC is smooth; rusted cast iron is jagged. It acts like Velcro, catching toilet paper and grease to create stubborn backups that a standard snake can’t fix permanently.
- Mineral Concrete: Over time, minerals from hard water bind with the rust, creating a rock-hard layer that restricts flow even further.
The Trenchless Solution: Don’t Dig Yet

If your home was built before 1980 and you have chronic backups, do not let a plumber talk you into a full excavation immediately.
At Drainiacs Plumbing and Heating, we specialize in Descaling. This trenchless method saves your floors and your landscaping. We use specialized high-speed grinding chains to safely shave the rust off the pipe’s interior.
The result?
