When designing your plumbing system, be sure to include a few ball valves. Ball valves will allow you to isolate different areas. This way, if there is ever a problem you can easily shut the water off to that specific area without needing to shut the water off to your whole house. Make sure that your ball valves are easy to access and that there is a place to shut off each faucet or fixture in case you ever need to find it in a hurry.
