Replaced all filter cartridges which showed significant sediment accumulation after 6 months of use. Cleaned and sanitized filter housings according to manufacturer protocols. Inspected brine tank and performed thorough cleaning to remove salt bridges that were affecting regeneration cycles. Recalibrated flow meter which was under-reporting water usage by approximately 15%. Checked all connections for leaks and replaced two worn O-rings on the main housing. Performed water quality test post-maintenance: iron levels reduced from 0.3ppm to <0.1ppm, chlorine effectively removed, and water hardness now at optimal 3 grains. System is operating at peak efficiency with properly sequenced regeneration cycles. Customer reported significant improvement in water taste and clarity following service.
