kman, don't reduce the pressure, more pressure, up to 100 psi is better for RO membranes, you want higher than 50 or 60 if you can get it. I run mine at 90-100 and it not only produces more water but it also gives lower final TDS too. You wil find you cant really regulate pressure with a gate valve or hose bib anyway, a 75 GPD RO only consumes about 1 quart of water a minute and you are not going to accurately regulate that. Open it up and let it go.
