This system is capable of producing more than 1000 GPD or 42 gallons per hour of pure water. Remove 94%+ of all parts per million from your tap water. Can produce up to 1500 GPD at 80 PSI with an optional booster pump. Save more water by running 2:1 waste to product water ratio, or optional 1:1 ratio (included). Includes custom KDF/catalytic carbon filter for reduction of chlorine, chloramine, iron, sulfur and heavy metals. Simple and quick setup.

This pump is designed to be installed before the Stealth RO to boost the inlet pressure. Wells and low pressure (below 40 PSI) water sources can benefit greatly from this pump. It boosts the pressure significantly allowing the Stealth RO to run with higher flow and more efficiency while having better TDS removal. The pump is designed for long service life and runs very quietly. Comes with a high pressure switch and operates at 110V.

Ensure your Evolution RO1000 runs more efficiently. Helps protect the RO membranes and extends their life. Less filter changes and maintenance - every 7,500 gallons of purified water. Cleanable sediment filter is re-usable. Combination of KDF85 and the KDF55 with eco-friendly catalytic carbon filter reduces chlorine, chloramines, iron, sulfur, and heavy metals. - great for city or well water. Highly recommended when using more than 150 gallons of purified water per week on average.

This float valve features a 3/8 in quick connect fitting and adjustable water level. Can be mounted vertically or horizontally. Stainless steel and PVC components. This float valve allows you to fill a reservoir or tank unattended to your desired water level. For use with the Evolution RO1000 Tall Boy™ or any other filter systems with 3/8 in tubing.

Replace membranes when product water decreases and/or ppm increase. Merlin Garden Pro and Evolution RO1000 membranes reduce 94%+ of total dissolved solids. Stealth RO100/200, Stealth RO150/300 and microRO-75 membranes reduces 98%+ of total dissolved solids. The Evolution RO1000 and Merlin Garden Pro systems need two (2) membranes. For all membranes, RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output.
