Why would the cold feed be backfeeding hot on a hot water heater?

The cold line is "upfeeding" hot. Both of the pipes running out of the hot water heaters(dual system) are hot. When we run the hot, it gets cold again. The cold feed pipe is hot until it reaches the T where it first splits from the main feed. Have had 2 plumbing companies out and nothing. All singke handle faucets and showers are off.
