In preperation for summer I'm replacing our old, leaking single speed pump with a new Pentair Superflo dual speed pump. The manual for the Pentair says that the inlet piping from elbow to the pump should be 5x the pipe diameter. I don't have that option as the old pump is close the exterior wall of the house. Do I need to re-do the pipe from the pool to give this distance? What is the impact of not having this recommended distance?
Photos are attached and any help is appreciated!
