How big is the main water pipe in the hotel 10 room?

The water supply and living pipes of the hotel are six branches.

Because hotels normally use tap water, the tap water pressure is generally high, so there is no need for large-scale water supply pipes. Under normal circumstances, the water supply pipes of water supply companies are all one-inch pipes, so the six-branch pipe is the most suitable for hotels, and then it can be used normally when it is connected to the basic four-branch pipe of each bathroom.
