Why does BRS recommend this?

The 150 GPD water saving upgrade kit is probably our most recommended RODI upgrade. If you have proper pressure (65+ PSI) we highly recommend installing the kit, because it will produce water twice as fast as a standard 75 GPD membrane while cutting the amount of wastewater in in half.

The BRS 150 GPD Water Saver Upgrade Kit will increase the production of any BRS 75 GPD reverse osmosis system to 150 GPD without having to use any additional water. With the installation of this kit water production will increase from approximately three gallons per hour to six gallons per hour! It does require 65psi or more into the first membrane in order to function properly and be effecient. If your home's water pressure is less then the recommended PSI do not worry, adding a booster pump is simple and only takes a couple of minutes.


Recommended Conditions:

  • Minimum Water Pressure - 65 PSI
  • Max Water Pressure - 90 PSI
  • Recommended Water Temperature - 77°F
  • Recommended Max TDS - <300ppm

Water pressure can be increased by adding a booster pump before your RO/DI system if a pressure increase is required. Low pressure will cause slow production of product water, with excess production of wastewater. Pressure over 90 PSI may cause damage to the RO/DI units filters and components.


Recommended Flow Restrictor - 550mL/min


What's Included?

  • One Dow 75 GPD membrane
  • Two 2.5" x 2.5" membrane clips
  • Two 1/8" x ¼" 90-degree elbows
  • 1/8" x ¼" 90° check valve
  • RO membrane housing
  • ¼" tube splitter
  • 5 Feet of Red, White, Blue and Black RO Line


DOW Filmtec 75 GPD Membranes have a 96% - 99% typical stabilized salt rejection rate that can be reproduced through the following conditions;

  • Source Water Pressure - 50 PSI / Membrane
  • Source Water Temperature - 77°F
  • Source Water TDS - 250ppm Softened Tap Water
  • Recovery - 15%
  • Minimum Salt Rejection - 96%


If you are purchasing a reverse osmosis unit from us at the same time as this 150 GPD Upgrade Kit please mention in your order comments if you would like us to install the unit for you.If you select this option, there may be a one day delay in shipping your order due to additional time considerations. 150GPD water saving upgrade kit is not recommended for units with high TDS* or drinking water systems**.


*High TDS - Source water with high TDS we do not recommend using the 150 GPD water saving upgrade kit. If used you may experience increased DI consumption. The system will work as intended increasing filtered water production rate and decreasing the amount of waste water, but the overall amount of TDS that comes out of the system may be slightly higher than a single membrane system. Because of that your DI consumption will increase. We do recommend using two DI canisters for 150 GPD systems.

**Drinking Water RO Systems - When filling up the pressure tank will increase the back pressure, in turn will take longer to fill and increase the waste water produced by the RO system. We highly recommend a permeate pump for these applications to minimize waste water.
