This Reverse Osmosis Permeate Pump will allow the Microline Reverse Osmosis Systems to operate even better than the out of the box units. They will increase the pressure to your storage tank, allowing the tank to hold more water. They will make the system run more efficiently without the high levels of water wasted that an RO unit can sometimes produce. The system will also work on all systems with individually plumbed filters. It does not work on most systems with a central plastic molded manifold. It does include the parts to install it on the Microline RO units.
