I have always been able to take a hot shower or a hot bath. Yesterday, I was unable to take a hot bath, the water turned ice cold very quickly. The shower loses hot water within 5 minutes. The sinks all give hot water. Recently I had a clogged drained in the kitchen snaked to remove the clog, could this have affected the water? If not then what could the problem possibly be. The thought of dishing out another $350 dollars for 15 minutes of work makes me ill.
