Best Backflow Preventer Certification in Plano TX

I accidentally created an ice skating rink in the street due to some kind of leak in the irrigation system. I had a plumber come out and close the valve, but they recommended I talk to an irrigation specialist since they can fix it for much cheaper. I contacted Steven and he was quick to respond and laid out clear expectations. What really surprised me was that he was able to come out the very same day I sent my request! He showed up when he said he would and got the repair done quickly. Before starting the repair, he did warn me that if the location of the leak was under the sidewalk it would cost extra. I appreciated the heads up and straight forward pricing. Fortunately it wasn't. I'd call Steven if I have problems again!
