No, soft water actually protects your plumbing and water using appliances. According to the US EPA’s Thomas J. Sorg, softened water does not increase lead and copper leaching in household plumbing systems. As long as your water has a neutral pH, softening it will not make it corrosive. Water that does not fall into the neutral range should be neutralized even if it is not being softened. If it isn’t neutralized, it will typically cause corrosion, whether it’s hard or soft.
Won’t soft water corrode my plumbing?
