What to expect
Replacement details
A single CFS 50 GPD thin film composite reverse osmosis membrane with a built-in check valve, for 4SV, 5SV, and ZeroWaste systems. These systems are built around the integrated check valve – without it the drain line can siphon and the system runs on instead of shutting off, so a standard membrane is not a substitute here.
- 50 GPD thin film composite membrane
- Integrated check valve – required on 4SV, 5SV, and ZeroWaste systems
- Membrane only – no prefilters, carbon cartridges, or post-filter
- Replacing like for like at 50 GPD keeps your flow restrictor correct
Compatible with: 4SV, 5SV, ZeroWaste
