- Run water through the system for 3-5 minutes to flush fines and settle media before use
COMPATIBILITY
Housing & System Fit
The Watts FI-EC10C fits all standard 10-inch filter housings designed for 2.5-inch diameter cartridges. Compatible with Pentek, Culligan, GE, Omni, and most other brands using the industry-standard 10" housing format. Ideal for under-sink systems, whole-house pre-filtration stages, and commercial applications requiring custom media configurations. The clear shell allows visual monitoring of media condition and flow patterns.
🔧 Pro tip: Pre-rinse granular media in a separate container before loading to remove dust and fines. This reduces initial flush time and prevents cloudiness during startup. For blended media, layer from heaviest to lightest to prevent stratification during backwash cycles.
