    Hey there, as the title states I'm looking into getting an ro/di system and was curious how many of you in the quad city area have found it necessary to get a booster pump. thank you in advance.

    Happen to know your water pressure on your house? If you're 50-60 or better, I think that's the recommended psi, a booster pump isn't really necessary but I think there can be benefits from running higher psi. If you're under that I would look into one right away.

    Booster pumps are really only needed if you have really low pressure, say under 30, really high TDS combined with low pressure, extremely cold input water, or if you're running 2 RO membranes with either of the above cases.

    I currently have my 75 GPD unit installed that's fed from a well, PSI at membrane is around 40, TDS is as high as 1200 tds, temp is 50 degrees or so, and my membrane still produces 98% rejection rate. I run a 1 micron sediment filter, a GAC/KDF filter, Carbon block x 2 and I'm very happy with the results. I wouldn't add a permeate pump unless you know it will solve a problem, not just to try to increase performance.
     
  5. I would recommend one to anyone, I can tell that I get less reject water. I save all my reject water for washing clothes and it takes a lot longer to fill a 55 gal barrel now than it used to without a pump.
    My ro/di kicks butt.

    Measure your water pressure before you worry about it. If you have adequate pressure and want more output you're better off running a dual membrane setup. I bought a single membrane setup with a pressure gauge to get started and once I saw I had good pressure I just ordered a second membrane upgrade kit. Had I just added a pump blindly I would have ended up having way too high of pressure and likely would have ruptured my membrane.

    Look at this. Thus may help to. Brs put on a booster pump and it preformed better and better.

    Thank you guys for all the input. I have seen that video, well probably all the videos they have made about rodi. I just wanted to see what the community does. I have heard the pressure will drop also as the first 2 filters become more used. I may just get the system without the pump and see how it goes before I spend another $100.
