I own a motel in Montana. We have a 2″ line feeding the motel from the water main. The city is in the process of replacing the existing 6″ water main with an 8″. When they hook us back up to the new main, they are planning on using a 1″ pipe for about the first 10 to 15 feet and splicing it onto our existing 2″. They tell me not to worry, it’ll have just as good of pressure as if it had a 2″ the whole way in. They said that the 1″ pipe out by the main, coupling to a 2″ pipe will still flow enough water to supply the entire motel. Is this true? Any advice would be appreciated. We have 23 rooms so there is potential of 23 showers running at the same time.
