Arizona Water Conditioning Equipment (CR-54) The CR-54 covers water softening, treatment systems, and filtration?areas where technicians often conflate residential conditioning with commercial-scale operations. Unlike broader plumbing licenses, this credential zeroes in on chemical dosing, resin regeneration cycles, and hardness testing, giving you the technical depth that general HVAC or pool certifications skip entirely.
