you have to figure out what pressure they are claiming 50gpd at. it could be 50GPD @ 50 or 60 or 100PSI. if the company isn't cheep they will use a 50GPD @ 50PSI... if they are cheep they will use a 50GPS @ 100PSI

This also explains why some people who buy 50GPD set ups only get 35 GPD out of them and some get more.

Basicly all TFT membrains have a max PSI of 120 PSI.. for a safe working pressure I would not go over 100PSI.

I just recived some new membrains from my supplier that are rated as follows.

75gpd@50psi, 100GPD@60psi and 160GPD@100PSI (this is one membrane not 3 different ones) I am rigging my RO up with two of these running at 100PSI so I will have a 320GPD setup.
