The Backflow Guy

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.

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!

These guys are the best when it comes to testing the backflow. We have been using them since 2013 and still getting them back each year.
I highly recommend using them for your backflow servicing and anything else to do with backflow.

Was referred by the fire designer and the whole process was seemless. Scheduled, inspected, and report sent out in a few days. Paid online and done! Very painless, will be calling them for next years inspection.

They are ON IT!! Came out as scheduled, submitted the report and invoiced me within two days of testing. You can even pay online, which is so convenient-- and about half the cost of what I was paying another well-known company! The Backflow Guy is now my Go To Guy. Highly recommend.
