    How to Determine Pipe Size

    The pipe needs to be the proper size to handle what it''s carrying (water, gas, air, drainage, etc.), but it also cannot be too small, or it could cause the volume to travel too fast. And that could cause serious issues, such as water hammer (a hydraulic shock or pressure surge), which in turn could damage the pipe system and the fixtures attached to the piping.
