Water Purifier Maintenance Checklist: Keep Your System Working Like New in Kenya
Introduction
Water is life, but only if it’s clean. If you rely on a water purifier at home or in the office in Kenya, maintaining it isn’t optional—it’s critical. Think of your purifier like a car engine: ignore it and it fails. But take care of it, and it keeps performing.
Understanding Your Water Purifier
Before we dive into maintenance, let’s understand what you’re working with.
Types of Water Purifiers in Kenya
- RO (Reverse Osmosis) – Ideal for borehole or salty water. 
- UV (Ultraviolet) – Effective for bacteria and viruses. 
- UF (Ultra Filtration) – Great for low-TDS water. 
- Gravity-based – Popular in rural areas with limited electricity. 
Common Features and Parts
- Filters (Sediment, Carbon, RO Membrane) 
- UV Lamp 
- Storage Tank 
- Tap/Faucet 
- Filter life indicators (in newer models) 
Key Components That Need Regular Attention
Sediment Filter
This is your first line of defense. It traps dust, rust, and debris. Change it every 3 to 6 months.
Activated Carbon Filter
Removes chlorine and bad odors. Also needs replacing every 6 months.
RO Membrane
The heart of the purifier. Replace once a year or sooner if performance drops.
UV Lamp
Kills microbes. It should be replaced every 12 months—even if it still lights up.
Storage Tank and Taps
Clean every month with mild soap and rinse thoroughly.
Monthly Maintenance Tasks
- Wipe down the exterior with a soft cloth. 
- Check for leaks around tubing and connections. 
- Inspect connections to prevent contamination. 
Quarterly Maintenance Tasks
- Pre-filter replacement ensures better RO membrane life. 
- System sanitization using a food-grade sanitizer or vinegar mix. 
Annual Maintenance Tasks
