Aqua FX RO Unit trouble

[KennyKen]

So im in the process of setting up my new tank, and went to start making the water.
hooked my ro unit up to a tap, and noticed a change in the waste/filtered water ratio. Extreme change.
About 20 gallons of waster water in a bout 6 minutes with less than an inch of filtered water.
I noticed the psi was a bit down, around 45. the unit says it needs 35 to function properly.

I replaced all filters and membranes, could this be the problem.? i mean i gave it time to break in (over 30 gallons.)

I contacted Aqua FX, but i assume no one will be in till monday.

Any suggestions.
