"Our house will be vacant for a few months this summer. What&amp;#039;s the best way to prevent water stains and rings inside the toilet bowls? -- Dottie J., Mansfield, OH Most plumbers recommend shutting down the toilets if you are going to be away for an extended period. First turn off the water (the shutoff valve should be behind the toilet on the floor or wall). Then flush the toilet, which will drain the water from the tank but leave enough in the bowl and trap so that sewer gases won&amp;#039;t escape into the house. When you return, turn on the water and give the tank time to refill. There&amp;#039;s still likely to be a slight stain from natural evaporation, but over a smaller area than if you had left water in the tank. "^^<http://www.w3.org/2001/XMLSchema#string>
