...the water to the house is turned off in the basement to prevent the pipes from freezing.

In basement, to the left of the steps are directions for turning on the water.

Before you leave, please turn the water off again (then drain the water from the faucets in the sinks).  Thank you!

In the basement, on the wall in between the blue Budaris boiler and the blue tank water heater, there is a metal box with a socket and switch.  Turn the switch to "off" for 5 minutes and then flip it back to the "on" (up) position.  Make sure that the little light on the front of the boiler is over the sun symbol and not the moon symbol.  That should do it!
