Troubleshooting
Diagnosing the most common problems
Common problems, likely causes
| Symptom | Most likely cause |
|---|---|
| Slow flow / low pressure | Clogged pre-filter, low incoming pressure, kinked tubing |
| Taste or odor returned | Spent carbon media, or a genuine source water change |
| Cloudy or discolored water | Trapped air (temporary) or failing sediment filtration |
| Unusual noises | Pressure buildup from a clogged pre-filter, or air in lines |
| Leaks | Worn O-rings, over-tightened housings, loose fittings |
Key takeaway
Over-tightened housings can actually cause leaks by cracking fittings - snug plus a quarter turn is usually sufficient.
When to call a professional
Persistent leaks after checking O-rings, consistently low output despite fresh filters, any electrical issue with whole-house or UV components, or simply not feeling confident diagnosing it yourself.
Frequently asked questions
- Is a small drip an emergency?
- Not usually, but address it promptly - slow drips cause meaningful damage over weeks.
- Why does taste vary day to day?
- Source water isn't always constant - disinfectant switches or seasonal changes can shift taste even with a working filter.
