To remove roots from a sewer pipe, which method is recommended?

• A. Treat with chemicals
• B. Use a cutting saw and catch the roots downstream
• C. Use a rodder with corkscrew
• D. Use a vacuum excavator

Answer: (B)

When roots block a sewer pipe, the best approach is to physically sever the roots and keep the debris from moving farther down the line. A cutting saw does exactly that: it slices through the root masses, leaving clean cuts that won’t easily re-enter or continue to grow into the pipe. Catching the cut material downstream prevents the loosened roots from causing a new blockage further along, making the removal effective and minimizing downstream problems. Chemical treatments only slow or dissolve roots over time and don’t provide immediate, complete removal. A rodder with a corkscrew can help clear some obstructions but often isn’t reliable for heavy root masses and may push roots deeper or damage the pipe. A vacuum excavator is great for removing loose material and for excavation safety, but it isn’t the standard method for removing entrenched roots inside a sewer line.
