We also installed our IceGuard technology into this home. The IceGuard is most commonly used for homes that experience freezing winters, just like in Michigan. This goes outside the home and automatically flows the water away from the exterior wall just in case the pipe freezes. The IceGuard allows any water to exit even when the pipe is frozen by having holes that direct the water out of the pipe when the pipe is frozen. When the pipe is not frozen, no water exits the holes.
