Replacing Your Clack GAC Filter

- 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.
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.
