The corrosive nature of certain chemicals found in drain cleaners, such as sulfuric acid or hydrochloric acid, can react with the metal pipes and cause corrosion. This corrosion can weaken the pipe walls, leading to leaks, cracks, or pipe bursts.

Metal pipes made of materials like iron or galvanized steel are particularly susceptible to the corrosive effects of drain cleaners. These pipes already tend to develop rust and corrosion over time, and the introduction of strong acids or other corrosive chemicals can accelerate this process.

As the chemicals come into contact with the metal pipes, they can eat away at the protective layer and expose the underlying metal to further corrosion. Pipes made of materials like copper or stainless steel are generally more resistant to corrosion and may withstand the effects of drain cleaners better.

What are the risks of using drain cleaner on plastic pipes?

Using drain cleaners on plastic pipes can pose risks and cause potential damage. The chemical composition of drain cleaners, particularly those containing highly alkaline substances like sodium hydroxide (lye), can have detrimental effects on plastic pipes such as PVC or ABS.

These alkaline chemicals can cause plastic pipes to soften, warp, become brittle, and eventually lead to cracks or pipe failure. The heat generated during the chemical reaction in some drain cleaners can further increase the risk of damage. However, not all plastic pipes are equally affected, as materials like CPVC or PEX may be more resistant.

To minimize the risk, choose drain cleaners specifically labeled as safe for plastic pipes, follow the recommended instructions, and avoid prolonged exposure. If unsure or concerned about potential damage, consulting a professional plumber for guidance on safe alternatives is advisable.
