Don’t say I didn’t warn you, disconnect your garden hose and shut off the faucet and drain the supply pipe. NOW! Every year people forget this little procedure and end up with a broken pipe and flood house. After the first frost you should definitely disconnect the garden hose or the water will freeze in the hose and the faucet and pipe. When water freezes it expands and the pipe will burst. There are two types of valves on the outside of the home the newer ones are called frost proof but can be shut off from the outside without danger of bursting. The older lawn faucet valves should be left open and shut off from inside the house. When you locate the valve on the inside there should be a little cap on the side of the valve to back drain the pipe. Make sure you do that.
