Base 4-stage BRS 75 GPD Value Plus RO/DI with additional DI stage from SpectraPure. The system includes a brand new Dow FilmTec RO membrane (never seen water), 4 DI refills, 5 carbon refills, and 6 mechanical filter refills. The DI refillable cartridges are brand new and have never seen water just like the new membrane. In addition, the system includes an additional digital TDS meter for a total of 4 measurable TDS points (inlet, out of RO, out of DI #1, and out of DI #2). In addition, the system includes a 120VAC solenoid and programmable timer to allow for controlled filling. The Value Plus series includes the RO shut-off and flush kit. This is all boxed up and ready to ship but it is HEAVY (30 lbs). Hence, I can do $165 shipped to the mid-west. Please PM for shipping to other locations.
