    Booster Pump Question

    For those, if any of you using a booster pump on your reverse osmosis, I was wondering what your incoming pressure before your membrane is with your pump on. Mine seems a bit on the high side, at anywhere between 132 - 120 psi.... The pump says 70-100 psi, so this is where I get confused... And the pump is 100gpd to go with my membrane.

    I read somewhere that it was unsafe to go over 90 psi...

    I just ordered myself a booster pump which is adjustable and i think its the way to go for not killing my Ro/Di unit. My psi is at 40 now, i will bring it up to 80-85 and see the result.

    how much water are you producing now compared to before?

    I get atleast 3x the water output then I did before. My pressure before wasn't bad, my well pump kicks in at 28 psi, and kicks out at 51 psi... Also, the pump is dead silent, I can't hear a thing from it even when I have my ear right next to it.

    i agree too, Running at around 65-90 will maximize your membrane and help with your productivity!
