In this manner, how does a crossover valve work?

Crossover valves open when the hot water temperature falls below 95 degrees Fahrenheit. When the valve opens the cool hot water is allowed to flow into the cold water line until the water in the hot water line reaches 105 degrees Fahrenheit. Once the hot water reaches 105 degrees, the valve closes.

Also, how do you tell which water lines are hot and cold? In most cases, the hot water is on the left and the cold water is on the right. Regardless of the style of faucet, hooking up the hot and cold water lines is relatively easy. Supply lines with integral washers are available at most home centers.
