Water Filter Maintenance

General Maintenance Principles

• Change filters on schedule — The single most important maintenance task
• Don't use hot water — Unless specifically designed for it. Hot water damages most filters.
• Keep housing clean — Clean during filter changes
• Check for leaks regularly — Catch problems early
• Monitor performance — Notice flow rate, taste, and appearance changes

Pitcher Filter Maintenance

• Hand wash pitcher monthly with mild soap (no harsh chemicals)
• Never put pitcher in dishwasher
• Replace reservoir water if pitcher sits unused for more than a week
• Store in refrigerator to inhibit bacterial growth
• Rinse new filters before first use to remove carbon fines

Under-Sink Filter Maintenance

• Check connections for leaks monthly
• Clean housing during filter changes (rinse with water, no soap)
• Inspect and clean O-rings; replace if cracked or worn
• Lubricate O-rings with food-grade silicone
• Sanitize system annually (per manufacturer instructions)

Whole House Filter Maintenance

• Check pressure gauges monthly (pressure drop indicates clogged filter)
• Inspect housing during filter changes
• Clean O-rings and apply silicone lubricant
• Check bypass valve function annually
• Consider professional inspection every 2-3 years

Reverse Osmosis Maintenance

• Change pre-filters every 6-12 months (protects membrane)
• Change post-filter annually
• Change membrane every 2-3 years (or when TDS rises)
• Monitor TDS with a meter to track membrane performance
• Sanitize tank annually (drain, add sanitizer per manufacturer instructions)
• Check drain line for clogs or buildup

Water Softener Maintenance

• Check salt level monthly; refill when below 1/4 full
• Use quality salt (pellets recommended over crystals)
• Break up salt bridges if they form
• Clean brine tank annually
• Regenerate manually if water feels hard

When to Call a Professional

• Persistent leaks you can't fix
• Dramatic pressure loss
• Unusual noises
• System won't regenerate (softeners, RO)
• Water quality issues despite new filters
