Many homes and businesses have old cast iron sewer pipes and experience mainline stoppages and backups much too often. Over the years, these old pipes naturally accumulate scale and rust on the inside diameter, making it rough for the paper to flow and often leading to a mainline backup/stoppage. We use state-of-the-art drain cleaning equipment designed specifically for descaling old cast iron sewer lines. Using a combination of custom-designed carbide-tipped chains and sandpaper, we can remove the old built-up scale/rust and smooth out the pipe’s interior surface. 


Unlike traditional clogs, the signs of pipe scale buildup aren’t always obvious. Below are some things to watch out for that can indicate it’s time to call our experts to descale cast iron pipe:

Cast iron has been used in drain and sewer pipes for many years and has proven to be a fantastic option for homeowners in the region. Unfortunately, cast iron is susceptible to scaling, which can restrict water flow over time. Thankfully, you can count on the specialists at Drain Mob for a full cast iron descale in San Diego, CA.

What Is Cast Iron Pipe Descaling?

The descaling process gradually removes the rusty flake scales built inside cast-iron pipes using a descaling cable with affixed descaling chain links. A set of tightly rigged chains, which hold steel nail scrapers on each chain link, rotates at high speed, creating friction in a filing motion that shaves the rust off the pipes. As the rust particles drop to the bottom of the pipeline, they are rinsed down the line with a constant high-pressure stream of water.

By filling the interior with rusty scales and flushing the debris down the drain, the descaling procedure opens the pipe for much better circulation. After removing the scales, the old cast-iron pipeline resembles a brand-new one in its look, circulation, and performance. Descaled cast-iron pipes function much better as those flaky obstructions that trap deposits every time a toilet is flushed are eliminated and the tendency of drains to stop up is minimized.

The descaling process typically starts at the drainage system’s end and continues toward the opening. Descaling could be a tedious process of filing the clog-creating obstructions, hydro-jetting the loose scales, and video inspecting to ensure high-quality work. Descaling takes patience and attention and, if done the right way, it should be time-consuming.
