My water heater hasnt been working right ever since someone broke a water line in town and we didnt have water for an entire day and a half. I didnt think about turning off my water heater until it was too late so I think the heating elements have messed up. I have some hot water but not enough to take a shower. That is until this morning and I dont have any hot water at all. Can someone tell me how to check and see if my water heater is broke without having to call someone.
