How Do I Prime My Shower Filter?
A quick flush removes loose carbon and prepares your filter for optimal performance.
Why Priming Matters
Every new shower filter cartridge contains activated carbon media that may have loose particles from manufacturing and shipping. Priming flushes these carbon fines out before your first shower, ensuring clean, clear water from the start.
Step-by-Step Priming Instructions
Before You Begin
- Ensure your shower filter is properly installed per the manufacturer's instructions
- Check that all connections are hand-tight and secure
- Have a towel nearby in case of minor drips
Priming Process
- Turn on the cold water: Start with cold water only to avoid thermal shock to the new cartridge
- Run for 2-3 minutes: Allow water to flow continuously through the filter
- Switch to warm water: After the initial cold flush, turn the water to your normal shower temperature
- Continue for 1-2 additional minutes: This ensures the filter media is fully saturated and flushed at operating temperature
- Total priming time: 3-5 minutes is typically sufficient
What to Expect During Priming
Normal Observations
During the first few minutes of operation, you may notice:
- Gray or black water: This is loose carbon dust and is completely harmless
- Small dark particles: Carbon fines may appear in the water stream initially
- Air bubbles: Trapped air in the cartridge will escape during the first run
- Slight pressure change: Water pressure may fluctuate briefly as air is purged
When Priming Is Complete
Your shower filter is ready for use when the water runs completely clear with no visible particles. If discoloration persists beyond 5 minutes, continue flushing until the water clears.
Tips for Best Results
- Prime your filter immediately after installation rather than waiting until your next shower
- Repeat this process each time you replace the filter cartridge
- If you notice carbon fines after your first shower, simply run the water for another minute or two before your next use
