Agree with GH85. Keep the water off until the house comes up to temp. Bring two helpers with you, send one to the second floor and one to the first. turn the water valve on slowly and have your helpers listen for leaks (gushing water). Keep and eye on the gauge to see how fast it is spinning. It will go fast at first until the pipes fill back up, but then should stop if no leaks.
