What is Backflow Report

ANSWER: Backflow is the undesirable reversal of flow of nonpotable water or other substances through a cross-connection and into the piping of a public water system or consumer's potable water system. QUESTION: Why do water suppliers need to control cross-connections and protect their public water systems against backflow?

I cannot say enough positive things about this company. They have assisted me in many of my last minute backflow needs, sometimes getting my water turned back on within hours. The team is quick to respond and react, always going over and beyond!

This was one of my neighbors back flows that have been fixed by dolphin. Second year of me calling to have them fix this for the gentleman who works there and speaks minimal English. They have refused to insulate it, stating it's not part of the job. I recommend Bob's backflow for any backflow work you need done
