Our water heater flooded our garage. I am assuming it needs replacing. I shut off the water to the house and the pilot on the water heater, but how do I shut off the water going to the water heater? What is the typical cost to replace a water heater?

Gosh asked:


All electric house. I am considering adding on demand water heaters in two places. They cost at least twice as much as a tank type.

Does an on demand burn the heater elements if the water is turned off? My tank type does burn out the heater elements if the water level drops below the elements in the tank.

Also, is the on demand water heater repairable or would a person have to buy a new one in case of failure?
