Subject: Water Mains
We all have a pretty solid grasp of what is meant by the AC Mains, but
what
in IEC language is meant by “Water Mains”?
In the US, when I think water mains, I think of the place down in the
basement where it enters my house. Using the analogy to the AC Mains, it
would be any place where I get water from the pipes, be it a shower head or
faucet. Any clarity out there today?
Thanks,
Doug Kramer

Doug:
I think the pipe that runs between the water main (typically under the public
street in the USA) is called a lateral.
Although I'm not a hydraulics specialist, I wouldn't call any plumbing within
a house a "main." In a commercial property, the term "main" just might be
applied to major in-plant distribution pipes (potable water, fire suppression).
Maybe the best description for a main is "the big pipe that you don't own."
