Hello, working on plumbing return layout, have the idea in my head of sending the uv return back through manifold port on the return with a separate DC pump I can regulate flow with. Is this going to mess with it or the tanks return pump flow since they will be going back through the same pipe to display tank? Also if I shut down uv to service or shut down return pump will this mess with sump water levels so much it isn’t worth the head ache and I should just get one of the cheap hang over return pipes and run the return line right up the back and into the display tank? Torn on this because I have a clean install going and this pipe and hose will be the only thing on back of tank. Thoughts on this, please and thanks in advance.
