Hi guys and girls need some help. I opened an outside water line yesterday and now I have no hot water anywhere in the house. I know the hot water tank is still producing hot water it is just not getting to faucets. Last thing hot water tank is natural gas. Any help would be greatly appreciated.

Perhaps opening the outside water line produced an air pocket in the water lines somewhere? Does cold water come out of the inside faucets? Maybe try letting the water run out of different faucets to see if air works it way out? My dad (RIP) was a plumber but he never taught me anything about this situation.

Try turning the outdoor hose bib water supply off again and see what happens.
Are you getting cold water outside?
Do you have a mixer on your hose bib supply that combines hot and cold water to give you warm water to the hose bib to wash your car?
Do you have a laundry sink that is very close to the tank? If yes, turn the hot on full blast and see see if you get hot water.
Touch the hot output pipe at the top of the tank and confirm that the pipe coming out of the tank is indeed hot.
If both the cold supply to the tank and the hot output pipe are cold, then you have a problem with the tank. Hot water tanks work by delivering cold water to the bottom of the tank and taking the hot water off the top of the tank. Even though on a gas tank, both pipes come off the top of the tank, the cold supply connects to an internal pipe that delivers the cold water to the bottom of the tank. It is not impossible for this pipe to break away and fall inside the tank. The result is about a minute of hot water followed by cold water.
How do you know that the tank is producing hot water?
Is the natural gas actually burning? Or because you hear the noise of the power vent running you assume that the tank is firing? Two different things. You need to confirm that the tank is firing, I.e. the natural gas is burning.
If the tank senses an overheat situation, it will shut down the burner, but the power vent will continue to run. And run and run in fact until you reset it. This can be caused by a sediment build up in the tank as Toronto municipal water has a lot of calcium suspended in the water. (You would need to flush the tank to fix that.)
