I have been going round and round with the contractors and plumbers installing new drainback Solar Water Heaters with additional storage tanks.
2006 IRC Section 2301.2.8 Solar Loop Isolation---- Valves shall be installed to allow the solar collectors to be isolated from the remainder of the system. Each isolation valve shall be labeled with the open and closed position.
2006 IPC Section 503.1 Cold water line valve----The cold water branch line from the main water supply line to each hot water storage tank or water heater shall be provided with a valve etc.
Do your jurisdictions require these valves to isolate the systems.
