If the property is hot-water heated, you open up the radiator valves on every radiator and drain the system from the compression tank in the basement and THEN add your antifreeze to the drain you used.If you have a property manager in the Northeast and he doesn't know how to winterize a property like this, he's a pretty piss-poor property manager.You would also probably be fine if you left the cold water on a basement faucet steadily running, the slowest continuous stream you coule adjust the faucet to produce just abive dripping.
