How often should I perform water filtration system maintenance?

Water filtration system maintenance should follow the manufacturer’s schedule, but most homes need filter changes every 3–12 months and a yearly system check. The main drivers are your water quality and how much water your household uses. In practice, we see filters load up faster after pipe work or a city line disturbance because trapped sediment spikes. Technicians who work throughout San Jose often adjust schedules for local hardness and seasonal sediment changes.

Typical maintenance cadence:

• Sediment or carbon pre-filters: replace every 3–6 months
• Whole-house carbon media/tanks: service or replace media every 6–12 months
• Reverse osmosis membrane: replace every 2–3 years
• Water softener: check salt monthly; plan a professional tune-up yearly

If you notice new tastes, odors, or lower pressure, service the system sooner rather than waiting for the calendar.
