RODI Question

Hi. I purchased a used BRS 5 stage RODI system in good shape. I’ve had it connected and running for 46 minutes and no clean water is coming out. A small trickle of wastewater has been coming out for 25 minutes. How long should it take to see clean RODI water start to be produced?
 
Does it have an ASOV valve?

Also - the DI resin comes after the product water - do you see it filling up at all? They may be a DI bypass valve that you can open to see if water is coming out of membrane output.
If you pressure is very low, it may be very slow (drips).
If the membrane dried out - it could be shot and mostly clogged.

Photos of the unit and plumbing would help.
 
Hi. I figured I just needed to tweak the pressure in the booster pump, that fixed the issue this morning. I put all new filters and resin in. Thanks for your suggestions.
