I'm currently having issues with running water. I have a utility sink that is running only hot water, but the hot and cold water throughout the rest of my home hasn't been working since yesterday. It's currently .5 degrees outside so I've considered the pipes to be frozen.. My home is on a slab and I know the pipes generally run along the back side of my house. I was curious if there might be an alternate reason for the lack of running water, as well as, what I can do to prevent the pipes from freezing in the future. Please Halp!
