Flex shaft cleaning is a modern, high-speed method used to restore old cast iron or heavily greased sewer lines. It uses a flexible cable with a chain head that spins inside the pipe, powered by a drill or specialized machine. As it spins, it scrapes away grease, scale, rust, and buildup from the inside walls of the pipe — all without damaging the line.
This technique is especially effective for cast iron pipes, where years of buildup can reduce flow or cause backups. It’s also excellent for kitchen lines full of grease and soap residue. After cleaning, we often follow up with a sewer camera inspection to show the results and confirm the pipe is clear and flowing properly,
