Sorry for the confusion. The slow drain is only during air draw cycle. After cycle ends water flow stops. Thanks for the advice. Im a tinkerer but agree I will wait for my own iron test kit to arrive so I can verify what I see and try to get the seller to resolve the issue. He has been nice so far so hopefully that continues and we can resolve everything. I do get the impression though that he normally puts a system in and its good to go without the issues I am seeing so hopefully he can resolve them without to much more costs.
