I needed to complete my annual backflow test, and he responded promptly to my questions and quotes…read more I received several quotes that varied widely in price, and his was among the most affordable. Before even coming out, he took the initiative to follow up with the city to confirm whether I needed the backflow test and to verify which valve required testing. He arrived right on time as scheduled and was very professional throughout the process. He truly went above and beyond. He submitted all required documentation to the city and county and also provided me with a copy for my records. I highly recommend him.

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.

Not enough effort is put into building an authentic relationship and it seems like people just do the minimum so that they can move on to the next transaction. Steve and his crew are regular people that treat others with kindness and respect not because they have to, but because that's who they are. They fixed a leaky pipe in my backyard without having to pull up my pavers and then they fixed a pipe in my front planter that solved low pressure on my drip lines. No fuss, no extra charges or unnecessary parts and labor. Steve's team obviously have deep knowledge and experience but what makes them so great is that they communicate clearly and are enjoyable to work with. Highly recommend them.
