Today a contractor installed a water line from the main to my house. During the tie in, the pipe continued to leak. The fitting thread was found to be defective, so the contractor placed 3/4 line about 16 inches from the main to the 1 inch line, and then fed the 1 inch to the house and water meter.
Will this 3/4 to 1 inch affect my flow or pressure? Is this ok to do? I am not 100% sure this was right.
