Plumber just did calculations for a home's water service, says minimums are:

and then

(2) 1-1/4-inch pipe inside the house until enough "units" fall off, then the pipe size can be reduced.

My question: how can a smaller 3/4-inch domestic water main pipe be made to support a much larger 1-1/4-inch pipe inside the house?
I've never seen 1 1/4" run in a house.

Have you considered running PEX?
