One winter a few years ago my husband had used the hose outside to spray something off on a warmer day and forgot to remove it from the faucet afterwards. A few days later I was in the laundry room while he was outside and suddenly water started pouring from the ceiling. Fortunately my parents were visiting and my dad was nearby to know enough that it was my husband using the faucet outside causing the flood inside. We got it shut off, put a new faucet in and pulled up the carpeting to dry everything out in the basement. It could have been worse but it was enough of a lesson for us to always remove the hose from the faucet and have the freeze proof faucets outside!
