Best Backflow Preventer Maintenance in Irvine CA

Andy did an amazing job, very fast even after hours. I kept searching for for companies that did fire sprinkler system and mostly were over priced and had to work with other company to do partial of the job, I was amazed Andy was able to get it fixed under 4 hours !! I will highly recommend California fire protection for any leaking fire sprinkler system. Very honest and reliable!!!

Had a backflow on my property for years and it wasn't​ until recently that I was mandated by the city to have it inspected. I called one flow and spoke to John who happened to be the owner. After a brief conversation on backflows, he realized he wasn't too far from my property and told me he could stop by after his current appointment. Upon arriving he gave me a crash course on the device and the importance of testing backflows. He then gave me a quote before any work was done (a real rarity with contractors). John provided​ Great customer service and provided testing the same day I​ called​! I will be using john and one flow for all my backflow needs in the future!
