What size ScaleSafe system do I need?
A. ScaleSafe comes in 1/2″, 1″, and 1 1/2″ inch line sizes. Each model has a corresponding minimum and maximum flow rate based on GPM (gallons per minute). Select a model that is compatible with the GPM flow rate for your system. Situations requiring higher than specified flow rates can be managed by installing multiple units with a parallel manifold.
