: I just purchased a home built in 1874. It has been unoccupied for approx. 4 years and has been
: "winterized". I first need to know what I need to do to de-winterize it. Do I only need to let the water
: run from all faucets for a day or so?

Winterizing involves draining down all of the pipes and putting antifreeze in p-traps. Running the water a bit should do it. I wouldn't leave the home with the water running. If a pipe has a slow drain, you could have flooded floors. Terry
