Signs that You Cast Iron Sewer Pipe Needs Descaling

If your cast iron requires descaling, it's wise to address the matter without delay. A blockage can lead to numerous complications, such as flooding, sewer backups, and water damage. Stay vigilant for these warning signs to help prevent calamities:

• Aging Pipes–Cast iron pipes were designed for durability and efficiency in the early 1900s. However, over time, these pipes became susceptible to scaling, and owners often unknowingly used drain cleaning products that accelerated the scaling process, leading to faster corrosion of the cast iron pipes. Over time, scaling formed on the inner walls of the pipe, gradually narrowing the diameter and leading to clogs as tissues became ensnared in the buildup along the surface.

• Scale build-up – As scale accumulates over the years, it leads to the formation of rough spikes that cling to the inner walls, which in turn reduces the water flow as toilet paper gets caught on these spikes, creating soft clogs. Consequently, you may find yourself resorting to snaking or calling the plumber more frequently, and this issue will only worsen over time.

• Cracks and Damage –If the sewer pipe is not properly maintained over time and scaling continues to accumulate within, it can lead to corrosion, particularly on the underside where water flows. This deterioration may result in cracks, allowing roots to infiltrate the pipe and cause further damage.
  

• Cast Iron Installation Costs - The costs related to the installation of new pipes can fluctuate based on the extent and location of the damage. For homeowners, this can represent a significant expense, particularly if the pipes are located in challenging areas, such as the lower levels of the property. This scenario can create a significant challenge for homeowners to manage, and it would be even more challenging if encountered during the winter months. The expense could soar into the tens of thousands of dollars to remove the flooring and install new piping.

• Trenchless pipe installations -  The ideal solution for a broken or cracked pipe is to opt for pipe relining. In this method, a technician employs a specialized technique to form a new pipe inside your damaged cast iron pipe. They then inflate a bag using air, ensuring a snug fit against the existing pipe. Once the material hardens, depending on the type and process utilized, the new pipe can endure for as long as fifty years.
