information on purchasing this product.



The 3M™ Scale Inhibition Treatment System helps extend the life of appliances that use hot water (e.g., water heaters and washing machines) and plumbing fixtures (e.g., faucets and shower heads). It balances acidic water conditions, lowering scale build-up and corrosion of pipes and fixtures. Scale build up inside pipes is what causes loss of water pressure because the inside of the pipe gets smaller and smaller over time. Less scale and corrosion means that water using appliances will last longer, require fewer repairs and will work more efficiently


  • Reduces scale to help extend the life of appliances which use hot water
  • Helps protect against scale build up inside pipes, which can cause low water pressure
  • Easy cartridge replacement -- screws on and off
  • Does not affect septic systems
