INSTALLATION & USE
Replacing Your RO Membrane
- Shut off water supply to the RO system and open the faucet to relieve pressure
- Remove the membrane housing cap and slide out the old membrane, noting the direction of water flow arrows
- Insert the new TFC-RS9-50 membrane with flow arrows pointing toward the output side of the housing
- Reassemble the housing, turn water supply back on, and flush the system for 30 minutes before use
COMPATIBILITY
System Fitment
This Good Water membrane is engineered as a direct replacement for Rainsoft TFC reverse osmosis systems, including models using the RS9-50 specification. It also fits compatible Sears and Kenmore branded RO units that accept standard 1.8" × 10" TFC membranes. Verify your existing membrane dimensions before ordering to ensure proper fitment in your housing.
🔧 Pro tip: Replace your sediment and carbon pre-filters before installing a new membrane. Worn pre-filters force the membrane to handle contaminants it wasn't designed for, cutting its lifespan in half.
