I may be in minority here, but I think Vancouver tap water with prime is good enough for most reef tanks. For soft corals it is certainly fine. We have great tap water here. Don't use the ro/di waste water, better off using tap water.

What the heck?

Waste water is cleaner than the water that you fed the RO unit...

What are you guys Putin' in yer water out there... Liberals. ( a joke ok)

If you say you have the same unit as the one on the site then something is wrong. A 100GPD membrane should have a constant stream of water being produced not a drop every second.

If not water pressure then your membrane may well be malfunctioning.

Does it have a back flush unit? because it minght be that the flush unit is not well adjusted? On my RO unit if this gadget is not well adjusted my unit only produce a few drops like yours.

just a wild guess here. This or it needs a new membrane. I usually pay around 50$ for a brand new membrane.
