A home water filtration system is an investment in health and taste, so it’s frustrating when problems arise. Two of the most frequent complaints are a sudden drop in water pressure and the presence of strange tastes or odors. Diagnosing and fixing these issues is often straightforward.
Diagnosing and Fixing Low Water Pressure
A noticeable slowdown in flow after filtration almost always points to a clog.
- Primary Culprit: The Filter Cartridge. Sediment and mineral buildup will eventually block any filter. This is the most common cause.
- Fix: Replace the filter cartridge. Always check the manufacturer’s recommended change schedule—often every 3-6 months. If you have particularly sediment-heavy water, you may need changes more frequently or a dedicated pre-filter.
- Secondary Checks: If a new filter doesn’t restore pressure, inspect for other flow restrictors.
- Fix: Ensure the filter housing isn’t cracked and the O-rings are properly seated and lubricated with food-grade silicone grease. A misaligned O-ring can cause a leak and impede flow. Also, check that the main water shut-off valve is fully open.
Diagnosing and Fixing Strange Tastes and Odors
Unpleasant tastes or smells typically indicate that the filter is exhausted, the wrong type for the contaminant, or that bacteria has grown.
- “Dirty,” “Earthy,” or “Musty” Taste/Smell: This is often caused by algae or bacteria in the source water or growing within the filter system itself.
- Fix: Replace the cartridge. To prevent recurrence, sanitize the filter housing with a dilute bleach solution (following manufacturer guidelines) during each change. Ensure stored filters are kept in a cool, dry place.
- “Chemical,” “Plastic,” or “New Hose” Taste: Common with brand new filters, especially carbon block models, which can release fine carbon dust.
- Fix: Flush the new filter thoroughly for at least 5 minutes before use. This clears any loose media and air pockets.
- Persistent Bad Taste with New Filter: If problems remain after flushing, your filter may not be designed to remove the specific contaminant causing the issue (e.g., certain sulfur compounds or chloramines).
- Fix: Identify your water’s specific contaminants (a local water report or test kit can help) and ensure you’re using a filter certified to address them, such as a catalytic carbon filter for chloramines.
Proactive Maintenance is Key. The vast majority of these problems are solved by timely filter replacements. Mark your calendar or use smart indicators. Regular maintenance ensures you consistently enjoy clean, great-tasting water at the proper flow.
