Great service and work. I have a commercial building that had a Backflow unit that was leaking. I got a couple quotes from different companies and The Backflow Guy was the lowest. They cane out and repaired my unit fast and the problem is fixed.

Fast, easy and painless! The Backflow Guy makes our burdensome annual backflow check as easy as possible, they do all the heavy lifting with reminders, scheduling and payment coordinated and seamless. Backflow no longer sucks my time. Thank you, thank you!

These guys (or guy) are great, they fixed my backflow preventer that was gushing out water. I first called a regular plumber and they were going to charge me $1000 to replace the whole thing, and they didn't even sound that confident they could do it. Eventually their boss referred me to The Backflow Guy. I called and got an appointment a few days later. The technician that showed up was very punctual, knowledgeable, patient and professional. He ended up finding two pieces of solder that were stuck in the valve so removed them, tested the backflow preventer for leaks before he left. Best part is I only had to pay the 1 hour service fee.

We have used The Backflow Guy for the last 3 years and have had great results with zero hassle. The company contacts me as a reminder that I must have this tested each year and then comes out and does the test and files the paperwork for me. Simple! Great service and I highly recommend.

I used The BackFlow Guy for all the years I lived in Atherton and they are GREAT! Very quick and takes care of everything for you. This is the group to go with.

Needed to have a report done for city water. Found Backflow Guy on Yelp. Great experience. The work was done right. The techs were polite and knowledgeable. The office was very easy to work with. I would recommend them highly

I was very impressed with The Backflow Guys professionalism and their expertise. The installation was quite difficult but their team pulled it off and the result is perfect!
We heartily recommend The Backflow Guy for all your Backflow Preventer installs and inspections.
I give Peter Weiss my 5 star recommendation.

I've used The Backflow Guy every year since 2013, and just wish that more home service providers could be as efficient and trouble-free. They show up, as scheduled, do their thing, send me the results and invoice, and they're done for another year!
