Why Roanoke Drain Lines Are Particularly Vulnerable to Blockages
In older Roanoke neighborhoods—such as Old Southwest, Grandin Village, Raleigh Court, and South Roanoke—homes frequently feature original cast iron drain stacks installed 60 to 100 years ago.
Over decades of service, cast iron undergoes internal tuberculation—a process where rust scale builds up inside the pipe, creating a jagged, snag-prone surface that grabs hair and toilet paper like Velcro. Additionally, the mature oak, maple, and pine trees that make Roanoke neighborhoods beautiful send deep root systems into cracked mortar joints of clay sewer lines searching for moisture.
At RCR Plumbing, we understand how to clear and protect these heritage systems without causing catastrophic pipe collapse.
