After receiving a woefully poorly constructed letter in the mail from my city that required…read moremandatory backflow repairs, I reached out to a number of vendors to help with my backflow repair. Some didn't respond, others couldn't do the services, others still only did commercial products. Pro Backflow on the other hand was responsive, offered reasonable prices, and ample availability. During my appointment, I found the service tech offered a good explanation of what he did and offered to file the paperwork for me with the city. My only two points of improvement is the service technician started the work on my house without even knocking on the door or meeting me. I just started hearing drilling. At best, it didn't matter, at worst, it could have been the wrong house! Second, I never hear back for days after the service tech left. I had to reach out to offer my final payment and figure out if they filed my paperwork. Overall good, but Pro Backflow can clean up the edges a bit.

Jaime was extremely quick to answer my questions! We set up a time and spoke before hand what he…read morewas going to do. Our Backflow was over 20 years old and had its days. And we had our shut off to our house replaced, including the valve. 28 years this shut off always hit the house to shut off. Jaime reversed it and now it's simple. Waited too long to change that out!! Jaime is a Professional and knows 100% all that he does! Could not ask for a better Professional and a job that was so expertly done!!! He also works on his jobs like it was his property, he takes pride in his work you can tell!!! Would always call on Jaime for any of these needs!!! Overall - EXCELLENT!!! TRUSTWORTHY!!!

I think it has something to do with the rewiring done. I reached out to Manuel via text and he ignored my text. I sent another text and he again ignored my text.

I was skeptically first because he told me they offered free estimates but a service fee cost so I really did not understand that. How is it a free estimate but charge for service fee even though it could be applied towards repair. Anyways, I provided Manuel a picture of what I was needing repaired and he was able to provide a reasonable quote and within a good timeframe. Installer reported as requested and on time and knowledgeable. We provided suggestions for concerns and really liked the unions on the pipes! Overall happy with repair and service. Would like to see other payment options besides Venmo.

Someone in an Aqua Backflow and Chlorination van was driving (not even) 60 mph in the left lane on…read morethe 91W. I went around the van and passed it since the freeway was WIDE OPEN ahead of this guy, and he flipped me off! Maybe these people are too emotional and unhinged to do your job correctly if they get this fussy and angry over someone passing them up on the freeway. I didn't even honk or flip them off or anything. Typical little man who can't control himself. Given the other review about a driver holding down the horn, I'm thinking they're roads ragers with hormonal problems. Is it that time of the month, big guy? Whatever makes you feel taller.
