Have you ever been curious what happens when a pipe bursts? Well take a glimpse at the frozen waterfall that formed after a pipe froze then burst!
When cold snaps happen pipes can expand and freeze, then when it warms up they shrink creating pressure that causes it to burst!!
A way to help prevent this is have a faucet run a small trickle of water to allow the water to keep moving, reducing the risk of the pipes freezing.
