"Sounds like the thermostat on the hot water tank is faulty on your system which is open vented hence water coming into your header tank."

"The pipe that is going back into the storage tank is the hot water vent pipe. When the hot water expands inside the hot water cylinder it travels up the vent and discharged back into the tank. It shouldn't be running back into the tank that often. Best get someone out to have a proper look at it.👍"

"The only pipe than comes from hot water tank to cold water tank is vent pipe which means hot water tank is overfilling which means feed to hot water tank is not shutting off."
