Follow the filter change schedule strictly for performance. Here's the order and typical timeline:
- Pre-filters (3 housings): Every 6-12 months. Sediment filter first, then carbon blocks. Change these first—clogged pre-filters kill membrane efficiency.
- RO Membrane: Every 2-3 years. This is the critical component for reducing dissolved solids.
- Post-filter (if equipped): Every 12 months.
Steps to change: Use the provided wrenches. Shut off feed water and tank valve. Relieve pressure by opening the faucet. Unscrew housing, replace cartridge, lubricate O-ring, re-tighten. Run water to flush for 10+ minutes.
If that didn't work: If water quality drops before schedule, test your feed water. High sediment or chlorine can shorten filter life. Consider a pre-filter upgrade.
Heads up: The product water must be tested periodically to verify the system is reducing total dissolved solids effectively. Keep a log.
