Re: Turning off water
Shup, we used to do that every week. Mom and Dad had a weekend place, and we'd turn the water off on Sunday, and leave it off till we got back again. Some places I know had their water off most all winter, and never had a problem. This was back in the day before whole-house filters, so what was in the water was in the pipes! The difference is we would always drain as much of the water out as we could. The toilets got a dousing of anti-freeze. We were on a water system, but had (still have) our own septic tank so the anti-freeze would go there, not to a county/municipal system. I wouldn't use anti-freeze now.
I don't think you have anything to worry about. City water is about as clean as one can get for the most part. There's nothing in the water to grow pesties that could bug you. If you feel weird, just drain it out.
I put it all back together better than before. There\'s lots of leftover parts.
