Watts Premier - Reverse Osmosis Membrane with Check Valve for FMRO4-MAN, WP-5 & WP-4V

The Watts Premier Reverse Osmosis Membrane with integrated check valve is the core filtration element for FMRO4-MAN, WP-5, and WP-4V systems, removing up to 99% of contaminants down to 1/10,000 of a micron. This semi-permeable membrane reduces TDS, sodium, arsenic, lead, perchlorate, chromium, copper, radium, and protozoan cysts including Giardia and Cryptosporidium.

COMPATIBILITY & APPLICATIONS

System Fitment

This membrane is engineered specifically for Watts Premier FMRO4-MAN, WP-5, WP-4V, and WP4-V reverse osmosis systems. The integrated check valve design ensures proper system operation and prevents backflow that could compromise water purity. The updated in-line flow restrictor technology used with this membrane eliminates the need to replace enclosed restrictors at each membrane change, reducing long-term maintenance costs. Ideal for residential point-of-use applications where high-purity drinking water is required.

💧 Pro Tip: Membrane life is directly tied to pre-filter maintenance. Replace sediment and carbon pre-filters on schedule to prevent fouling and maximize the 2-5 year lifespan of this RO membrane. Low water pressure or off-taste are early indicators that pre-filters need attention before membrane damage occurs.
