Backflow Testing

The backflow testing process checks your plumbing to ensure dirty water does not infiltrate the drinking water supply. This can happen if the system loses pressure.

Testing is due annually, and failure to provide acceptable test results by the due date may result in fines. Sprinkler systems are required to have a backflow prevention device.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″ css=”.vc_custom_1629924009184{padding-top: 10px !important;}”][vc_column_text]
