I am surprised at all the local weather reports of our sub freezing temperatures for today, Monday and into the next 48 hours, but no one is mentioning to crack your faucet levers and keep a water drip going !!! I lived in the Dallas-Ft Worth area back in the early 1980's when they had similar temps like now, and homeowners water pipes were bursting all over town including some water mains ................... Crack your faucets so they keep a steady leak going and this will keep the water in the pipes moving, instead of freezing up in the pipes !!!
