anyone know how to shut off the water to your house?

Find it now, before you need it. The main stop valve is usually where the pipe comes into the house: low on a basement or crawlspace wall on the street side, under the kitchen sink, in a utility room or garage. In warm climates it's sometimes outside by the foundation. A lever valve is off when the handle sits across the pipe. A round wheel turns clockwise. Turn it while you're calm, old wheel valves often seize, and you'd rather find that out on a quiet Sunday than with water pouring through a ceiling. If yours won't move, there's also a valve at the meter or the street, but that usually needs a special key and may belong to the water company.
