The advice about turning off the water from inside is the best solution. Having said that, I don’t always do it. The weather has been so variable over the last few years that turning the water on and off got to be a hassle. I do shut if off when we hit the main stretch of winter, but I use covers to guard against the unseasonable freezes that happen on either side of that. I have not had any problems over several years of this, so I think I can say that they work.
