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.

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!!!

Every year the county (Los Angeles County, CA in my case) requires Backflow testing. Since I had to…read morelook up exactly what it is, "In order to protect our drinking water quality and prevent the spread of infectious disease and other contaminants, mechanical backflow prevention assemblies are utilized to prevent used, unclean or contaminated water or substances from entering the potable / domestic water system. To prevent contamination, it may be necessary to install testable backflow prevention assemblies to prevent backflow from occurring. In Los Angeles County, these assemblies must be tested every year by a backflow tester certified by the County of Los Angeles. My HOA has been utilizing the services of Dakota Backflow since 2001, when the units were first built. I like the streamlined, nearly or completely paperless process: County sends forms to HOA, sign and either snail mail or email pdfs back to Dakota, they do the testing, certify, sign, send back to both HOA and County. I like the smooth,efficient process, and if I have questions, an email takes care of it. It's customer service that works for me! Dakota is great to work with with an easy to follow process. I have received other backflow company ads this year and I like Dakota and they are priced well. Jane of the HOA :-)

The employee said they don't usually have those in stock, but it's cool that they did have on in case someone needed it right away. They are located off of 4th street and Hermosa and maybe 2 miles from the 10 freeway and Archibald Ave. They are across the way from Top Golf!
