Calling those responsible for these lines may save you having to call the plumber.
Winter Tips - Disconnect garden hoses and drain. Leaving hoses connected can cause the pipes inside the wall to freeze. Close crawl space vents if temperatures are going to the teens, leave a faucet in the highest part of the house on with a pencil lead sized stream. If your kitchen or bathroom sink is on an outside wall, leave the cabinet doors open so heat can get to the pipes.
If you know the brand and model name or number of your fixtures, it can help the plumber complete your repair sooner.
When you have new fixtures installed, save the part information in a safe place. It may be years before you need it, so put it where you can find it.
