The Citymaster is Aquatell's perfect softener for homes and cottages on municipally supplied water that's moderately hard. Compact yet powerful, our purpose-selected components produce a high-performing machine that will deliver years of luxurious soft water and save you tons of water and salt in the process.

The Citymaster is built with a genuine USA-Made Clack™ upflow-regenerating control valve and Canadian-made 10% cross-linked resin. The Citymaster softener is designed with the do-it-yourselfer in mind:

  • your choice of plumbing connectors
  • push-to-connect brine line connections
  • pre-loaded softening tank
  • valve is pre-programmed
  • bypass valve, plumbing connectors, and drain line connectors are all hand-tightened - no tools required
