Reverse-osmosis membranes are consumables. Over time they foul, take on salt passage, and lose production. If your salinity is climbing, output is dropping, or the system has been sitting unused, a fresh membrane is often the fix.
New membrane (Filmtec / Dow or equivalent), pressure vessel inspection and O-ring service, system flush, and post-install salinity verification. We coordinate the specific membrane part number for your Sea Recovery, Spectra, Village Marine, FCI, or HRO system.
