    123 Backflow has excellent customer service. They went above and beyond to not only make sure my Backflow test was done in a timely manner for the district, every step was done with excellence. From my initial phone call, follow up call, pre-tech texts, and actual appointment experience- everything and everyone was friendly, professional, and operated excellently. That even included sending me a picture of my tech before he arrived. Many companies still don’t do that yet. As a new customer, I was very impressed and my work was done and submitted to my district within minutes.Thank you Kelly, Sebastian, and Tom the tech!Thank you 123 Backflow!!I will be back again for sure.Use them today, you will not be disappointed.

    I used their service (annual inspection of RPZ device) for the first time this year, and I will use them for the next 20 years or more. Technician came on time, reliable service, great people, friendly and affordable. I wish all contractors were so professional as "123 Backflow Testing". I highly recommend this company to everyone. Thank you.
