INSTALLATION & USE
Replacing Your Clack GAC Filter
- Shut off water supply to the RO system and open the dedicated faucet to relieve pressure.
- Locate the inline GAC post-filter housing (typically positioned after the storage tank and before the faucet connection).
- Unscrew the housing cap, remove the old S-7025 cartridge, and inspect housing interior for sediment or debris.
- Insert the new Clack S-7025 filter, ensuring proper seating, then hand-tighten the housing cap until snug.
- Turn water supply back on, check for leaks, and flush the system for 5 minutes before use to remove carbon fines.
COMPATIBILITY
Designed for Clack & Hydrotech Systems
The S-7025 GAC filter is engineered for Clack Microline and Hydrotech reverse osmosis systems that use proprietary inline post-filter housings. This cartridge is not a universal fit—verify your system uses Clack part number S-7025 or Microline part A1013473 before ordering. It serves as the final polishing stage in residential and light commercial RO configurations, removing any residual chlorine taste that may pass through the membrane and improving overall water palatability.
🔧 Pro Tip: Always flush the new GAC filter for at least 5 minutes to clear carbon fines, which are harmless but can cloud the water initially. Mark the installation date on the housing with a permanent marker to track replacement intervals.
