I'm interested in installing a hot water recirculation system, with a dedicated return line. The dedicated return line will be made of 1/2" pex. What should I look for in a pump? Should I make the return line enter the hot water tank at the cold supply side with a check valve? Or is there a better design for the return water? The system will have 5 or 6 feet of head. What's a good brand name of pump?
