From the National Weather Service, Ft Worth:
Category: Freeze Warning
For the next few nights, temperatures will fall below 32 degrees.
Please make sure your faucets and out buildings are protected from freezing.
It is going to be very cold over the next 3 or 4 days with evening temperatures well below freezing. The last time we had below freezing temperatures, we had 5 townhouses that had burst pipes, 4 of them were in the two story out buildings and one was a pipe in a second floor outside wall that burst and flooded both floors.
Those of you who have washer connections either in a 2 story out building or in a room off the carport, please make sure pipes are wrapped and protected. Also make sure your faucets are protected.
Please cover your outside faucets and protect water pipes in the out buildings (washer connections on 2 story homes).
Protect your pets:
Please make sure that your outside water faucets are properly wrapped to prevent freezing during the low temperatures over the weekend. Townhouses which have outside washer-dryer hookups also need to either heat the room or make sure the pipes are properly insulated.
Make sure that you disconnect any hose attached to the faucet before thermally wrapping them. The water that remains between the hose connection and the actual valve (which is inside the wall) will freeze and fracture the pipe after the valve itself; learned that the hard way.
Home Depot, Lowes and other home stores sell foam faucet covers fairly cheap, like $3 each.
