01
Verify equipment certifications and performance claims
For a cation-exchange softener, verify the exact model and its NSF/ANSI 44 certification claim. Compare water and salt efficiency using documented product specifications. If complementary treatment is proposed, verify which specific target and certified reduction standard it addresses rather than accepting general purity claims.
02
Confirm installation scope, discharge, and permits
Check what equipment, plumbing adjustments, drain discharge connections, old unit disposal, and post-installation tests are included or excluded. Confirm who pulls required plumbing permits and schedules inspections for your municipal address.
03
Account for ongoing salt, water, and service needs
Total operating expense depends on your household water demand and equipment efficiency. Factor these recurring requirements into your decision:
- Estimated salt consumption based on hardness settings.
- Regeneration water volume required per cycle.
- Periodic filter cartridge replacements and planned maintenance.
