Very knowledgeable and professional
We had a city inspection for a commercial building, and one of the backflow valves would not test out, we found out today. The company that did the testing referred us to DNA Plumbing. We called today and registered our account, and today at 2:00 p.m. a DNA person looked at our plumbing backflow problem and within 5 minutes gave us a quote and ordered the parts for us. We are scheduled with DNA to repair the plumbing on Monday. The DNA employee was very knowledgeable and professional in every way. We will definitely call them again!

I’m Clearly Very Happy With DNA Plumbing!
I called DNA Plumbing, Heating and Air, on Tuesday morning and by Tuesday afternoon I had a crew out here, Brian and Carlos, and they explained to me what the situation is, and we saw it when we turned the water on outside in the yard in a terrace: it was a broken, old backwash stop, and it was broken between them in the brass, so the whole thing had to be replaced. When we agreed on the quoted price, they got the parts, because they’re not common parts, came back, and before the afternoon was over had the water back on and an up-to-date, up-to-code backwash valve put on the feeder line to the house prior to the filter I have in the garage. Their work was done professionally. Both Brian and Carlos know what they’re doing, and they set forth immediately to putting it in with the right tools, working together because it is up on a terrace, which made it a little bit more difficult, and finished it out making it look professional, pea gravel and all! Brian and Carlos are a good working team, they think within conjunction of each other and get the parts that are necessary and work well together to make the end result most excellent! So I’m grateful for the repairs that Brian and Carlos did, and I’m grateful for the company sending out the right people to do the right job, and I’m clearly very happy with DNA Plumbing!

Chad provided a competitive estimate
Chad came out and provided a competitive estimate to replace some outside leaking facets. He also provided some valuable information about which facets needed backflow valves and which did not.

Customers for Life!
Taylor came to our rescue this morning and was like a breath of fresh air and made us feel like we were in the best hands possible after we were stood up by American Home Shield and A-USAir. Taylor came in and stayed until the problem was resolved and didn't quit on us until the job was done. He was friendly, professional, and extremely knowledgeable in his field. We would highly recommend DNA Plumbing to our family and friends. Customers for life! The Birdines
