    Hi, as the title says the water pressure has gone really low where I am, they have just built another 20 houses down the end of the road so i'm not sure if that's anything to do with it? but still getting a high reading after ro would the pressure effect it that much?

    Yes if you have 2 bar then you will only get around 94% rejection rate . For example input 100 ppm then output 006 ppm.

    That's a 125 psi rated membrane that is more suitable for commercial ro systems not wfp systems so you will need a booster pump.
