The Ultimate Water Purification Maintenance Checklist

You’ve invested in a quality water purification system—great move. But like any system, it needs regular maintenance to keep performing at its best. Whether you have a reverse osmosis (RO) system, carbon filter, UV filter, or whole-home solution, proper upkeep protects your water quality, your appliance life, and your health. Here’s your go-to maintenance checklist to keep your system running smoothly all year long.

Monthly Maintenance Tasks

• Check for leaks around filters and connections
• Inspect water pressure and flow rate
• Test water quality (use in-home test strips or digital testers)
• Clean faucet aerators and showerheads if you notice reduced flow

Quarterly Maintenance Tasks

• Replace pre-filters (sediment filters or carbon filters, depending on system)
• Sanitize RO holding tank and lines (if applicable)
• Clean and inspect UV system housing (if installed)
• Check softener salt levels and top up if low

Annual Maintenance Tasks

• Replace RO membrane (typically every 12 months, unless otherwise specified)
• Replace UV lamp (even if it still lights up—effectiveness degrades over time)
• Perform a full system flush (especially for well water or high-mineral content areas)
• Schedule a professional system inspection for peace of mind

How to Know It’s Time for Maintenance or Replacement

• Drop in water pressure or taste quality
• Cloudy, smelly, or discoloured water
• Filters feel slimy or disintegrate
• RO tank takes longer than usual to refill

Keep Your System Running Like New

Neglecting maintenance doesn’t just affect water quality—it can lead to system damage, costly repairs, and reduced appliance life. Staying ahead with simple checkups is the best way to protect your investment.
