The CraftBrew Water E-Series 6000 reverse osmosis system is available in two configurations: float switch-controlled or pressure switch-controlled with a 62-gallon reverse osmosis pressure tank. Each system includes a 6 GPM UV unit, a blending valve, a TDS meter, and is pre-wired and plumbed for anti-scalant integration. It’s economically priced, made in the USA, and ships free within the continental US, though shipping restrictions do apply.
