# Why Am I Having Issues After Replacing My Filters?
## Minor issues like air in the lines, taste changes, or pressure fluctuations are normal after a filter change and typically resolve within a few days of use.
Replacing your filters is one of the best things you can do to maintain your water filter system. However, it's not uncommon to notice a few temporary changes right after installation. Most of these are perfectly normal and resolve on their own. Here's what you might expect and how to address any concerns.
---
### Air in the Lines
Sputtering water or irregular flow immediately after a filter change is usually caused by air trapped in the system during installation. This is the most common post-replacement issue and is completely harmless.
- Run the water for 5-10 minutes to flush air from the lines
- If sputtering continues, turn the system off, wait a few minutes, then run the water again
- Air should clear within 24-48 hours of normal use
---
### Changes in Water Taste or Odor
New filter media can sometimes produce a slightly different taste or faint odor during the break-in period. This is normal and indicates the fresh filtration media is activating.
- Flush the system according to your model's instructions (typically 10-20 gallons)
- Allow 1-3 days of regular use for the taste to normalize
- If unusual taste persists beyond a week, double-check that filters are correctly seated and the right model for your system
---
### Pressure Changes
You may notice a slight difference in water pressure after installing new filters. A modest decrease is normal as fresh media offers more resistance than worn filters.
- Minor pressure reduction is expected and often improves after the initial break-in period
- Significant pressure loss may indicate an improperly seated filter or a clogged pre-filter
- Ensure all housings are hand-tightened securely but not over-tightened
---
### Leaks Around Filter Housing
Leaks after filter replacement are typically caused by installation issues rather than defective parts. A quick check usually identifies the problem.
- Verify the O-ring is properly seated, clean, and lubricated with food-grade silicone grease
- Check that the filter is the correct size for your housing
- Ensure the housing is tightened evenly, snug but not forced
- Inspect the O-ring for cracks, debris, or damage and replace if needed
---
### "Cloudy" or "Milky Water"
Water that appears cloudy immediately after a filter change is almost always caused by tiny air bubbles, not contamination. Fill a glass and watch it for a minute—if the cloudiness clears from the bottom up, it's simply air.
- Continue flushing the system to release trapped air
- Cloudiness from air bubbles should disappear within a few hours to a day
