The oxidative nature of chlorine poses a documented threat to residential plumbing and appliances. Many internal components, specifically elastomers (synthetic rubbers like EPDM and Nitrile), are highly susceptible to chemical attack. Chlorine causes these polymers to undergo chain scission, where the molecular bonds are broken, leading to "embrittlement"—a state where the rubber becomes hard, loses its seal, and eventually cracks. This is a leading cause of premature failure in toilet flappers, dishwasher seals, and washing machine hoses. Furthermore, under specific conditions, chlorine can accelerate the pitting corrosion of copper and stainless steel, potentially shortening the lifespan of water heaters and fixtures.
