I want to know, since I am removing all my plumbing in the basement and re-doing it. I have two redundant array pumps in case one fails, but they are too powerful when running together. They move 2200gal each. They are magnet pumps. I have two questions.\
1.Which return pump runs the coolest. I know ceramic shafts transfer less heat from friction.
2.what is the lowest watt pump that moves the similar amount of water.
