Well, y'all ain't heatin' up the cold water are ya? Nope. Turn the spigot for hot water heated up by the hot water heater. You want the cold water to come out cold.Lol. One of my favorites is when people call a water heater a “hot water heater”. You dont need to heat water thats already hot. Another one is “hose pipe” when referring to a hose(a water hose). Its simply a hose. I grew up in the South and I cannot stand that one.
