Thanks for all of the responses!
I did a little more testing: I measured the rate of the water coming out of the
RO membrane, and it's about 6 minutes per cup. That's about 1 gallon per 1.5 hrs. If I bypass the prefilters and connect the source water directly to the
RO unit, I get a rate of a little over 3 gallons per hour; that's closer to what I'd expect. Although I assume that there would be a little less pressure when flowing through the pre-filters, just not that drastic of a difference.
I'll have to take the prefilters off tomorrow and see if I can find a blockage that I didn't notice before when I examined them.
Thanks!
Jason
