Watts Premier 531417 Reverse Osmosis Review

This Reverse Osmosis system consists of four stages of filtration based upon these treatments: sediment pre-filter reduces dirt, silt and rust; the carbon pre-filter reduces chlorine taste and odors and conditions the water before it is treated by the reverse osmosis membrane; the 50 GPD membrane reduces TDS and other contaminants like chromium, arsenic, copper, lead, and the VOC Carbon Post-Filter reduces chemicals like MTBE's, atrazine, benzene, 2,4-D, and lindane Sediment (WP105311), Carbon (WP105351), 50 GPD Membrane (WP105331) and Post VOC Carbon (WP105381). The system includes a RO Pure Reverse Osmosis module with four pre-installed filters; a parts bag; a brushed nickel, top-mount twist faucet, and 3 gallon storage tank giving you crystal clear, high-quality, and great-tasting drinking water. This space-saving, compact design allows this system to fit comfortably under your sink, requires fewer tube connections, includes back-flow prevention valves installed between the elements and cartridges have double O-rings so they won't leak. The easy, quick-change push release filter system allows for easy filter change with no need to shut off the water source, is installed with check valves in the filter lid between cartridges to prevent back-flow and shut off valves in each filter head that shuts off the water flow when cartridges are removed. Maximum operating pressure is 80 psi and to maintain top performance replace sediment and carbon pre-filters every 6 months, VOC carbon filter every 12 months, and the membrane every 2 to 5 years.
