    Was wondering would too much water pressure damage the membrane? I have quiet good water pressure and my RO unit seems to produce more water than what it's rated for?

    most home units are supposed to run at about 4 - 4.5 bar pressure.
    we had about 7 bar pressure at work and it also ran more water than supposed to , but the membranes didn't last more that 2 months.

    one day ( thank goodness we were at work ), the plastic membrane cover shot off completely and poured water out, just leaving the thread on the unit from the membrane cover.

    We put a inline pressure regulator and set it to 4.5 bar and all is well again.
