I have been reading years of posts on the DIY Cerges Reactor. All examples seem end with flow restriction. The solution has been a dedicated pump and plumbing. I suspect many people don't ensure 1" ports and fittings remain consistent all the way through. Anyone have experience tying 1" lines to 1" ports on the water filter housing and still have flow restriction? Anyone done this without problems? For a cheap DIY, I am coming in around $100 with all 1" parts.
