While up in NY, taking the advantage to plan my plumbing,, WOW what expensive quality ball valves are.. Going 2 inch from the pump all the way to the bulkheads and to in from the sump to the pump intake.. Also going with flex pvc and a y valve on the output of the pump to minimize friction that elbows cause.. Am planning to do a regular durso, unless you guys know of something better, and a feed bar that runs down the middle of the tank with loc line shoots about every foot or so..
