As long as you get the correct flow retrictor soon its should not matter. I just wouldn't go too long.
The 150 GPD membranes are a sweet deal if you can get one that really delivers 150 GPD at close to 98% rejection. I have witnessed problems with them producing 98% efficiency. Spectrapure tried them recently but had trouble getting them to pass their rigid standards so dropped them. They are the only vendor who bench tests their membranes that I am aware of so others may be relying on Dow's word that they work. Most vendors will not guarantee a membranes performance so you may or may not get a good one?
