I need advice on plumbing my return. I’m using the Cor-20 pump that recommends 1.25” return line. I will be reducing that line down to 1” close to my bulkheads. I have an Apex, and want to use their flow meters on my line. One of the pictures shows a 1” flow meter at each bulkhead and the other picture shows a single 2” flow sensor close to the return pump. I’m also going to be running a manifold above the sump.
Which of these options would be best? Can anyone suggest better options on the plumbing? Different design etc?
