Anti syphon valveReplacement

LMI's diaphragm back pressure/anti-syphon valves apply positive discharge pressure to a metering pump system and act to stabilize the output of higher output LMI Metering Pumps when pumping into low or no-pressure systems.

So I have a new build house, and the water heater is at one end and most of the hot water demand. Such a showers in the kitchen is at the other end of the house. As you can imagine we wait a long time for hot water. My brother-in-law, who is a licensed plumber, suggested we install a recirculation pump and crossover valve to fix that problem.

He didn’t explain exactly how this works-if I have a pump that’s pumping the cold water out of the hot water pipes and the crossover valve at the furthest, end of the system, doesn’t this compromise the ability to get cold water? Doesn’t this dump a bunch of hot water into the cold pipes?

LMI's diaphragm back pressure/anti-syphon valves apply positive discharge pressure to a metering pump system and act to stabilize the output of higher output LMI Metering Pumps when pumping into low or no-pressure systems. Pressure relief valves are designed to protect chemical feed systems from overpressure damage caused by defective equipment or deadheading. Valves are available in sizes:1/4”1/2”1”Available MaterialsPPPVCPVDF316SS

Or does it run all of the time and if that’s the case, wouldn’t all of the lines in the house basically carry hot water? It seems as if you would need a third line to act as a return to water heater to have hot water on demand as well as cold water.
