    Why does BRS recommend this?

    Being able to monitor and maintain your RODI system is almost a necessity to know when your filters need service and if a problem does arise, having a pressure gauge and TDS meter makes trouble shooting much easier. The TDS meter will let you know when your DI resin is fully exhausted so you are not relying on color change alone anymore.


    Ideal for 75 GPD and 150 GPD Water Saver RODI Systems

    The BRS Value to Value Plus Upgrade Kit, will allow you to add the accessories to upgrade the BRS 4 stage Value RODI system (and most other RODI systems) to a BRS 4 Stage Value Plus RODI system.


    Kit Contains:

    • Dual Inline TDS Meter DM-1 - HM Digital
    • Glycerin Filled Pressure Gauge 1-100 PSI
    • 550 mL Flow Membrane Flush Valve


    Glycerin Filled Pressure Gauge 1-100 PSI

    Sufficient PSI is very important for the correct operation of a reverse osmosis unit. Low water pressure is a leading cause of poor RO system performance. A pressure gauge assures that proper pressure is being supplied. It will also make pressure drops apparent which can tell you that sediment and carbon blocks need to be changed.

     Glycerin filled pressure gauges absorb vibration and pressure spikes increasing service life. This glycerin filled pressure gauge comes assembled with 1/4" quick connect fittings for quick easy installation in-line before the RO Membrane. This item is designed for use with our saltwater aquarium line of RO systems.


    Dual Inline TDS Meter:

    The DM-1 Dual Inline TDS Meter from HM Digital is one of the most important reverse osmosis accessories. This tool monitors the TDS of your reverse osmosis system in two places and lets you know exactly how the system is performing.

    BulkReefSupply.com suggests installing the dual TDS meter post membrane and post DI stage. These two readings will notify you when it's time to change the RO membrane and DI resin. This unit features a digital display and comes with two 1/4" John Guest Quick Connect Tee's.


    550 mL Flow Membrane Flush Valve

    Reverse Osmosis membrane flush/flow restrictor valves increase the flow to the membrane by bypassing the flow restrictor when the valve is opened. This helps flush deposits and significantly increases the usable life of the RO membrane. The Membrane Flush/Flow restrictor valve is an all in one flow restrictor equipped with a flush valve for easy worry-free use. Keeping the flush and flow restrictor in a single package keeps the number of connection points to a minimum which means less chance for possible leaks or failures down the line. BulkReefSupply.com recommends flushing the membrane before and after each use for a few seconds, or every few weeks for a few minutes as part of regular reverse osmosis system maintenance. When the handle on the valve is “in line” the valve is bypassing the flow restrictor and is in “flush mode,” if the handle is perpendicular to the valve, then the unit is ready for normal use.

    Product Questions

    It looks like there's two upgrade kits, 550ml and 800ml. I have a 75 gal/day unit and am planning to upgrade to the 150 with water saver. Which of the value plus upgrade kits would be best, the 550ml or 800ml?
    Thanks for you help.

    Hey there,
    Thank you for reaching out to us. I would go with the 550ml unit. This should work effectively for you in either of the units you go with. Please let me know if you need anything further.

    Hi, I have purchased the BRS value 75 GPD rodi unit. I want to use this upgrade kit on it. Do I need to purchase anything else besides this kit to do the installation? thanks
