When temperatures get near freezing, you may need to close up shop for the winter. Here's how:
1. Clean and cover the grill.
2. Turn off and unplug all other appliances, such as a fridge.
3. Shut off the water supply, and flush any remaining water from
the pipes. (This is easiest if your plumber installs a gravity-based winterization system; otherwise, you'll have to pump the water out.)
