We moved into our new home, as I've noted, on November 15. And we've had encounters with various sales people already: One man was selling furniture from an 18 wheeler (no thanks); one was selling meat packages from his truck(we bought one package); one was selling water treatment equipment. Whoa. Water treatment? Come in and let's talk. The water here is very unpleasant to drink; it is heavily chlorinated, and also very hard, with calcium and other minerals in it. Since the home is new (so is the plumbing and our appliances), we want to do whatever we can to protect our investment. Last night, the man from the water treatment company came out and showed us with some simple demonstrations just how hard the water really is. So we bought a system, and it is being installed now. It will be about 3 days before we can drink the water, but for other uses it will be fine in the meantime. And we do have bottled water for drinking. We will save money in the long run, on soaps and cleaning agents, on plumbing, and even on appliance repairs. I say it is money well spent, plus we won't have to worry about health problems like kidney stones, which can form when water is very hard.
