    Easily the best customer service Ive ever had from a business.I had a problem with the DEP not accepting my backflow test results due to the original test being filled out incorrectly by Build It Backs architect.Tom and his staff helped me through the entire process,Contacted all the involved parties,And rectified the situation.They saved me a lot of money in fines,And alot of stress,And asked for nothing in return.

  • DeQuan was friendly, professional and efficient. The price was half of what I paid last year. So glad I found this company!

    I am a member of a condo board in NYC, and had a GREAT experience with our first appointment with 123 Backflow. They are very responsive and professional. The technician who worked with us, Ari, was knowledgable and did a great and thorough job servicing our building. He answered all our questions and provided a positive and informative experience.
