Yes you need to shut off the Main water valve. Usually found in the basement or outside the house near the meter. Also you need to shut off the Gas valve located at the water heater, or the Breaker located in the breaker box/ fuse panel. Sometimes the water heater will have its own Switch box, located on the power wire
no need to change the copper tube if the capacity of the unit is same.
Water heaters should be turned off, with the gas or electric to them turned off as well, when replacing any hot water lines. This would also be a good time to drain the tank and remove any built up water scale. This makes your heater more efficient.
Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes
