Is the water from the fire hydrant the same as tap water?

1, all the way. For example, the municipal fire hydrant installed on the municipal water pipe network adds water to the fire truck, and the water it produces is tap water. In addition, the fire hydrant inside the unit is also a pipe for tap water, and the water coming out is tap water.

2. Not all the way. For example, the fire hydrants in some units are separate fire water supply networks. The water source is the water in the fire pool. The water in the pool may also be tap water or well water, so its outlet is different from tap water.
