PROCEDURE FOR TURNING OFF WATER AT THE BACKFLOW PREVENTER

For residents of the Port who want to turn their water service off while they are away for
extended periods of time please follow the following instructions:

To extend the service life of the backflow preventer you will turn off the valve after the
backflow.  This will ensure that the gaskets, o-rings, etc… will remain under pressure and wet
while the water is off to your home.  In the picture you see that the side of the backflow is
marked with the direction of flow.  The valve located at the discharge side of the backflow is
the proper valve to shut, as shown in the picture.













If you have any questions please call the office at 239-642-9219

Thank You-
Bert Underwood
