Aqua Tec Aqua Tec ERP-1000 Aquatec AQUATEC-ERP-1000 Permeate Pump Black

The Aquatec ERP-1000 Permeate Pump is a non-electrical device that uses only the hydraulic energy of the 'brine water' (normally lost down the drain) to push additional purified water ('permeate') into your pressure tank. This is a great add-on. Increase your RO efficiency as much as 400 percent!
