Of course it expands -- but not nearly enough to cause an explosion, unless it boils.

Also, as I pointed out previously, water isn't the only thing that expands when heated. The steel tank does too, increasing it's volume.

I don't think it matters, one large one or two small ones. I'd probably opt for two small ones.

That would be terrible.

But I have nothing like that. I have a garden hose I use for less than 2 hours a year, and when i use it, it just has a nozzle and no container to siphon from.

Water was off one day for 3 hours working on line own street. Told us to open big sink cold water spigots to clear the air out of the lines. The water was nasty brown. I guess that normal for old lines.
