Bobby, I'm not sure what there is for specific guidance. What I usually try to do is keep all of the suction pipe the same size (or larger, if distance is an issue) as the pump suction. I also like to valve each tank so if a problem develops, then you can isolate the tank and keep the system in service. The value of that has been debated on the Forum before, but I still prefer that arrangement. The pump or tank manufacturers might have something to say about it, too.

We are installing a 13R system. There is a pump room with (5) 400gallon
plastic tanks that will be piped together. Is there anything that gives
direction for the requirements for piping materials, valves, etc. between
the tanks and pump?



Thank You,
