  4. Turn the water supply back on, check for leaks, and flush the system for 5 minutes to remove carbon fines before use
COMPATIBILITY

System Requirements

The Watts WQTCGAC-10 cartridge is designed exclusively for Watts QT reverse osmosis systems that use 10-inch by 2.5-inch standard size filters. This GAC pre-filter typically occupies the first or second stage position in the filtration sequence, ahead of the RO membrane. It is not interchangeable with the Watts WQTCBC-10 carbon block cartridge, though both serve the QT RO product line. Always verify your system's filter configuration and sizing before ordering replacement cartridges.

🔧 Pro Tip: Run a full flush cycle after installing the new GAC cartridge to clear carbon fines from the system. Black residue in the first few glasses is normal—it's harmless activated carbon dust, not a defect. Let the system flush until the water runs completely clear before reconnecting the storage tank.
