The Citymaster PRO is Aquatell's perfect water softener for homes and cottages with very hard water and/or water that contains high iron + manganese. High-Velocity (HV) resin and the rugged and long-lived Clack™ upflow-regenerating control valve combine to produce outstanding softening results even in very challenging environments.

The combination of up-flow regeneration and HV resin also means that incredible efficiencies can be obtained. The Citymaster PRO can regenerate using as little as 21 gallons of water and 3 pounds of salt achieving a Softener Efficiency Rating (SER) of 5,000 grains per pound of salt used.

The Citymaster Pro 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
