RO/di machine headache

Yeah, that ain't right. Should definitely be more than a drip coming from the product line. I have a fixed 75 gpd restrictor built into a manual flush valve assembly, no adjustment but is simple & works fine.

You say the water is pouring out the waste line, perhaps it's your adjustable restrictor that's the problem, could be as simple as that. Try plugging the waste line completely to see what happens. If you have a JG end plug, just use that, but don't run it too long that way, just long enough to see if you get more than a drip from the product line. Depending on the outcome of that scenario, logic would dictate that either your adjustable restrictor is toast, the membrane is toast, or water pressure is being bled off/lost somewhere upstream of the membrane.
