the main coming into my house is 3/4 inch copper. As soon as it comes through the wall it is reduced to 1/2 inch and that is what is run throughout the house. My friend told me to replace the hot and cold mains throughout the house with 3/4 inch, but where it tees off to fixtures or applicances, leave it at 1/2 inch. He said it would increase pressure at each fixture and when someone flushes the toilet, it wont affect the shower if someone is taking one, or reduce the pressure at other fixtures. Is this true?
