Bleach is commonly used for cleaning and disinfecting surfaces, including those in plumbing systems. When it comes to PVC (Polyvinyl Chloride) pipes, using bleach in moderate amounts and diluted forms generally does not cause significant damage. PVC pipes are designed to withstand various chemical interactions, making them resistant to the corrosive effects of bleach, especially in domestic concentrations. However, frequent use of highly concentrated bleach can lead to gradual wear and reduce the lifespan of PVC pipes by causing the plastic to become brittle over time. It is important to ensure that any use of bleach for cleaning purposes involves dilution as per manufacturer recommendations and is not a regular practice for pipe maintenance to avoid potential long-term damage.
