Water Fixers can help customers stay on schedule with RO filter changes, membrane changes, and system maintenance reminders.
Routine filters are commonly changed every year or sooner depending on the system and water conditions.
The RO membrane is typically a multi-year service item and should be tracked separately from routine filters.
Maintenance also includes leak review, flow review, pressure/tank review, faucet performance, and whether an upgrade is needed.
