Replacing Your GAC Cartridge

  1. Shut off water supply and relieve pressure by opening the faucet. Remove the filter housing using a filter wrench.
  2. Remove the old cartridge and clean the housing interior with mild soap and water. Rinse thoroughly to remove any residual carbon fines.
  3. Insert the Watts GAC20NRW cartridge, ensuring proper seating in the housing. Check the o-ring for damage and apply food-grade silicone if needed.

COMPATIBILITY

Standard 20-Inch Housing Compatibility

The Watts GAC20NRW fits any standard 20-inch filter housing with a 2.75-inch inner diameter, including Watts, Pentek, Culligan, and other major brands. This cartridge is typically installed as a second or third stage in under-sink reverse osmosis systems or as a standalone carbon filter for municipal water treatment. Replace every 12 months or 5,000 gallons, whichever comes first, to maintain optimal chlorine and chemical reduction performance.

🔧 Pro Tip: Always flush new GAC cartridges for at least 5 minutes before use. The initial black water is harmless carbon fines, but flushing prevents sediment in your first glass and extends the life of downstream components like RO membranes.
