Sooooo if you do this you actually have NO water pressure. What is the
point of preserving pressure if every one turns their water off?

So that the fire hydrants still work. They're talking about [reventing
low system pressure (due to thousands of broken pipes), not your house pressure.



Sooo I can see that but there are broken fire hydrants too...spewing water.

I suppose they didn't think it necessary to use the northern style
fire hydrants where the valve itself is belowground.

Or silcocks with the valve well inside the structure (and pipes routed
inside). For once in 120 year problem, it's probably more expensive
than it's worth, if anyone in Texas even remembers how to do it.

When I lived in Vermont, one Winter we had water mains 7' down,
freeze. It got very cold right after a good thaw. The saturated soil
allowed the frost line to go down very deep, very fast.

I did have a frost-free silcock freeze once. I forgot a hose
connected to it. As it froze, the silcock froze and cracked because
it couldn't drain.
