I wish I could give them zero stars! We asked them to come out and perform our annual commercial backflow test because our usually provider was unavailable. That was a mistake! The couple come across as very nice people but are very unprofessional. They had to use our electricity because they couldn't get their generator to work. They charged our company card with the wife's inflatable business CC account so the charge comes up on my credit card statement as the inflatable business not OH No! Backflow. A couple of our valves failed so they gave us an insane repair quote of around $15,000. We got a second opinion for the repair quote and ended up paying $2,800 with CALCO. Oh No! Backflow said that they submitted the reports to the City of Griffin, but here we are 4 months later and the City still has not received them. We have requested a copy of the report multiple times from them for our records and still have not received them either. So basically we paid for nothing because we have zero reports to submit for the city. If you need a great company to service your backflow needs. I would highly recommend CALCO.
**Response to Oh No! Backflow's response***
You were not called out on a Saturday. 4/30/2026 was a Thursday during normal business hours. Yes, you had to pump out our vault and we were charged for it as to be expected. You also used our electricity to pump the vault out because your generator did not work. You had said that if you came back out to perform the repairs you would do it on a Saturday so that it did not disrupt our production, but as I said your testing was done on a Thursday during normal business hours. As I said in my review, the City of Griffin still maintains this morning that they never received your reports. I don't know whether that was a system error or an error on your part. read more
