Questions about Pumps

[sphelps]

Have you considered leaving the CL dart as is and replacing the return pump with something a little smaller? With the CL already in place I wouldn't take it out as it will be more efficient at creating in tank flow than a return. The bigger source of the energy consumption is the hammerhead. I'm assuming you're pumping from another floor with that pump? If so have you considered any options to reduce the pump head pressure like raising the sump?
