anyone have a water pressure gauge for RO?

I dont think the system does, and I didnt read the RO membrane before putting it in, but from what I've read about other systems, it is a minimum PSI of 50 and 77C for best performance

Filmtec membranes are spec'ed at 77 degrees, 50 psi, and 250 ppm feedwater. Other brands are similar, except they are spec'ed at 60 or 65 psi.

50 to 65 PSI however won't give you the best performance however - the higher the better, up to about 90 PSI. I say 90 because typically there is at least one component in an RODI system (not the membrane!) that has a max operating pressure of 100 PSI.

For those w/o a pressure gauge - instead of spending your money on a hardware store gauge, think about adding a pressure gauge kit to your system. Not only can you tell what your home's pressure is, you can also use it to tell when your prefilters are clogging.
