Frequently Asked Questions
 

• What is the Watts OF1252RM OneFlow Anti-Scale Replacement Media used for?
  Watts OF1252RM replacement media helps prevent hard water scale buildup in commercial and industrial plumbing systems. It uses Template Assisted Crystallization (TAC) technology to transform dissolved hardness minerals into microscopic crystals, reducing their ability to form scale deposits.

• Which Watts OneFlow system is compatible with OF1252RM replacement media?
  The OF1252RM is designed for the Watts OF1252-30 OneFlow Anti-Scale Tank System, which has a maximum rated flow capacity of 30 gallons per minute (GPM).
