Corrosive drain cleaners, such as those on supermarket shelves, frequently cause injury to plumbers or homeowners when they open pipes or sink traps to do repairs. Use non-corrosive drain cleaners—they are better for safety and the environment.
Treat faucets gently; when turning on and off, use normal hand pressure only.
Use caution when using hanging toilet bowl deodorants. They are prone to slipping and lodging deep in your plumbing system. Certain chlorine tablets may also corrode toilet tank components, leaving you with a major hard-to-get-at leak.
Use lemon peel in garbage disposal once a month to keep odors at bay.
