Dont turn the water on at all until you can get in the house. and then have people stationed on each floor to listen and watch for leaks.OMG what a RISK. even with a house being properly winterized by a so called professional company things fail.Just to mention a few,, outdoor sill cocks.. dishwashers,, ice makers in refrigerators, washing machines, and radiators. to mention a few some forget,  any and everything that's had or supplies water in it is potential for a leak and you won't know till your there and turn it back on.When you do turn water on DO it SLOWLY,  have faucets open and as water starts running and air is forced out then turn off each faucet.
