Straightline Backflow, Inc. is a family owned and operated business.

We provide backflow testing and backflow repair for commercial, residential, apartments/condos, and construction sites.  Customers scheduling appointments with us for annual backflow testing, includes us completing the testing paperwork that you received and submitting the test report(s)/results on your behalf to the requesting water agency.  

For contractors, we provide backflow testing and certification for new installed backflow prevention devices, which includes us submitting the completed test reports to the assigned water purveyor and leaving completed test report(s) onsite for inspections.  

Moreover, we provide testing on existing backflow devices for contractors needing testing done to complete inspections.
