The PENTAIR GRO-2550 is a 4-Stage high recovery reverse osmosis system. While most systems produce a 3:1 ratio of drained versus potable water, the GRO-2550 offers a 1:1 ratio. Therefore, it eliminates unnecessary water waste and produces a much quicker recovery time. This system allows you to make up to 50 gallons of fresh water per day. Reduces salts, dissolved minerals, and bad taste and odor. Also Designed for chlorinated and non-chlorinated potable drinking water.
