My well has a combination of 3/4" pvc and reinforced plastic tubing for the intake, one ball valve between the high-speed pick up and the pump. The valve allows me to shut off the flow when I don't want water in the well. A 1" pvc coupling serves as the drain out the side at the bottom, epoxied in (rough it up with 30 grit before glueing). The coupling takes a cheap boat plug. The overflow is a 1.5" bulkhead that also goes out the side, with a plastic strainer inside. Openings in the strainer are small enough to keep my smallest baits in, and has enough surface area to not clog easily with debris that comes in with the cast net.
Bottom line...pvc is fine, but I would make your overflows bigger. You are pumping through the smaller intake but relying on gravity (head pressure) for the overflow.
Thanks for the input Cape-Man, Few questions. Your High speed pick, do you use the pump when on plane to bring water in and is the vents in the pickup pointed aft? If yes to either, do you have any problems with it not pulling in water at planning speeds? Is the pick up protected from getting hit or sucking up mud/sand when in shallow water?
Your logic is reasonable for the 1.5" strainer overflow, makes sense to drop bait directly in from cast net.
My design is cut off valve at intake, a tee, then pump. Flow control valves to each tank and shut off valves to each drain back to the tee before the pump. The drains will be used to recycle water back through the system for when the boat is loaded at the end of fishing trip or in very shallow water.
When ready to drain the system the flow goes back out the pick up. The plan is a overflow from bait well to live well and the live well then has a over flow out the side. I do a lot of catch and release so the bait well will be used more often than the live well.
Thanks again to everyone that provides input,
