I know that some folks totally against running the skimmer to a settling chamber and I understand that! Let's put aside that discussion! If I have to plumb my 3" line skimmer gravity feed to a large 500Gal settling chamber together with a 4" botton drain. And if I don't restrict the flow, which line will get the most flow to its potential? I wanted to know that, so I can decide which line should I install the ball valve to regulate the flow. My guess is that the skimmer line would get the max flow to its protential, so I should put the valve there to restrict its flow to allow more flow to the BD.
What do you think?
