I have a slight concern with my 6 stage RODI system from BulkReefSupply. I've changed several filter kits over the years but never came into any issue. Prior to replacing the filter kit, whenever I am finish making my RODI water, the water flow from the waste line and the clean water will almost immediately stop, but after replacing this one the water flow will still flow for several seconds give or take about 6-10 seconds. It doesn't sound like a big deal but any changes prior and after replacement will always raise a concern in my head. Initially there was air traps in the line which was resolved after flushing the membrane but weird and odd that the flow still continues on after shutting off the main water source (faucet). Also, the only thing that I unplugged was the red line (see picture). anyone have any idea or have similar issues? I've contacted BRS but awaiting their response. Any advice, comments, tips will be greatly appreciated! Thanks in advance!
