I just got my RO/DI installed, and it's producing water, but at a very slow rate. It will be nothing, then a slow drip or a stream, and then nothing again. The waste water is flowing like every other RO?DI unit I have seen in action. It is a Water General unit, purchased from Filterdirect.com. Anyone have one of these or have an idea why it's so slow? As previously posted, I did have to run the drain and fill lines almost 25 feet to get to the nearest sink. Thanks.
