The San Bernardino County Building Code provides that every mountain resident should have one shut off valve to their water system. Many shut off valves are located in the build-up area of the house near the water heater or where the main water line enters the home. However, this location does not protect the line from the meter to the house which is the property owner’s responsibility.

To protect the service line as well as the irrigation system and main household water system, the recommended location for a shut off valve is on the customer’s side, outside of the District's meter box.

Shut off valves should be clearly marked with a stake or pole that will be easy to spot in the snow. All family members (and your patrol service if you have one) need to know how to locate and operate the valve.

Please remember that only authorized District personnel may turn the District's water meter off and/or on.

If you plan to have a shut off valve installed, please notify the District’s Customer Service staff so they can schedule an inspection to make certain it is installed according to District standards. Click here to download connection specifications.
