Designed for Watts Premier WP-4V Systems
This filter set is engineered as a direct replacement for Watts Premier WP-4V reverse osmosis systems and compatible models including the Premier 4SV and 5SV series. All cartridges use industry-standard sizing: 10"x2.5" drop-in format for pre-filters, a standard 1.8"x11.75" membrane housing, and a 10"x2" inline post filter with 1/4" NPT female threaded connections. The 24 GPD membrane (Watts 560014 compatible) is suitable for residential applications with typical household water pressure and temperature. This set provides a complete annual service kit for maintaining optimal system performance, including sediment removal, chlorine and chemical reduction, reverse osmosis filtration, and final polishing. Reuse your existing post filter fittings during installation.
