How does cold water heat up?
Cold water can also heat up by being too close to a water heater or forced-air heating duct. When the supply lines sit too closely to these heat sources, the radiant heat transfers to the cold-water pipes. This affects the water temperature flowing through the adjacent water lines though the effects are often temporary.
Why does hot water flow out of a cold water tap?
Pipe proximity is one cause of hot water flowing out of the cold water tap. When pipes run parallel and are seated too closely, heat can pass from the hot water side to the cold.
