Friendly, thorough, and knowledgeable. This was our first “blowout” - moved here from Texas. He had to crawl under the house to find the shut off valves! Great job!

Josh came out in spring to do a backflow test. He was quick, educational, and just a nice guy overall. We then recommended him to a friend and our friend had an excellent experience as well. Will be contacting Josh again when it comes time to shut things down for the winter. Thanks again!

It is incredibly easy to schedule with H2O Flow and they are communicative the day of their service with more accurate ETA windows. They showed up, did they job, and rolled out in a quick manner. I've used them for some seasonal work with my sprinklers and will keep on using them
