## Description

ERP-500 permeate pump is a simple, yet revolutionary, device. Powered only by the hydraulic energy of brine water, the ERP-500 requires no electricity. the permeate pump forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure. Dramatically improves the efficiency of RO water production, reducing wastewater by up to 80%. The permeate pump can also bring storage tanks up to line pressure and shut the system down when the tank reaches capacity, eliminating the need for an ASO valve. Other benefits include higher delivery pressures, faster RO water production, superior water quality, and extended filter/membrane life. Includes a sound suppression insert which helps the system operate in near silence. Package includes ERP-500 pump, mounting clip, SS screws, and installation instructions. The ERP500 can easily be retrofitted to existing RO systems. Install after RO flow restrictor.

Review: Fixed Low Pressure and Expansion Tank Not Fillling - My expansion tank on my RO system stopped filling up about 6 months ago. This had been installed for about 5 years and was US Water brand RO system. It never really had great pressure at the faucet but worked ok. When it stopped filling the tank I tried new filters, new membrane, and any of the components that might help with pressure. I even took pictures of the whole setup to US water to see if they could see something I may be doing wrong. All to no avail, still little to no RO water!! At wits end I bought this permeate pump and it solved the issue. After I bought the permeate pump I found a youtube video made by US water as to how to install. Super super easy to install and now have perfect water pressure at the faucet and the tank fills as the system was designed. If you have pressure problems on your RO system and have eliminated any obvious problems you should give this a try. 100% satisfied with this very reasonably priced solution.
Review: Must have for an RO system. - If you have an RO system you should have this pump. I had a pressure pump that did not help at all and ended up leaking and ruining a door. After removing the pressure pump and installing this Permeate pump, the RO operation improved greatly. Better flow and pressure, more efficient and does not use any electricity.

### ⭐⭐⭐⭐⭐ Must have for an RO system.

### ⭐⭐⭐⭐ Works well
*by M***Y on November 14, 2022*

Instructions are hard to follow, had to find a proper instructional video for installation, i think it was the third video i found that had the correct process. Process may vary depending on filter system, i installed on a express water ROALK5D, i think the one thing i can say that may help others is that you know the pump is running properly if you hear it clicking, see the brine out flow lines pulsing and not a consistant flow. If your flow restrictor is in the wrong place or your lines are wrong you will most likely see a constant flow from you waste water or brine out line and the pump won't click.
