Plumbing repair. Came out because hot water is coming out of the hose bib. I installed a new water heater yesterday, and yesterday was the first day they used the water hose this year. After investigating, I found that this winter the lines in the basement froze, and another contractor repiped the basement. They crossed the hose bib into the hot water line. He is going to call the previous contractor out to fix the issue they created. No charge per Jake.
