After years of having American backflow do my annual backflow test with no fuss, they really dropped the ball this year.

A tester came out in early July and, due to some overly enthusiastic spring mulching, 'couldn't find' my back flow device (its in the same place it was last year, I guess the company doesn't keep any notes?). Instead of knocking on the door or calling, he filled out a form saying they couldn't find the device but that they would contact me to reschedule.

It's now late august, they have not contacted me to reschedule.

I get that the company might have a policy about not digging around in customers' mulch, but i think it took me less time to clear the mulch after finding the form than it took the technician to write it out. Why fill out a form and leave instead of even trying to contact the owner?

Owen came out on a Saturday and found our Backflow device that the city and another plumber could not. Took Owen less than five minutes. What a great employee and a great company. I highly recommend American Backflow to anyone needing these services, and if your really lucky maybe you will get Owen.

Happily, the owner of American Backflow contacted us concerned about our recent experience. He arranged to come to our home and make right the situation that one of his plumbers left us with.

Tony came to the house, took care of everything that we'd called them for in the first place, and made some recommendations for us to consider in the future. His work was of the high caliber that we'd always come to expect from them, and we will be using them for any of our future plumbing needs.

Thank you for restoring our faith in your excellent company.

They tested our irrigation backflow device as a subcontractor for Cornel's plumbing. There was no problem with the testing. One issue was that their web presence is clearly in need of some updating. There is no e-mail address or functional web form. Their website was developed in 2016 and parts of it are still missing. What worked though was a chat through Google maps.

I needed a backflow installed at my home, and didn't really know where to start. I have very old plumbing and I was very wary about people being in and out of my home in a pandemic.
American Backflow sent out Owen, and I'll admit, even though I had a lower quote from another company, he and the owner of the company, Tony, sold me on going with them.
I've never had a more polite service person in my life. Owen showed up on time, masked when I asked, and bent over backwards to be helpful in explaining the job. Tony got on the phone with me to explain my options. (Ok, their scheduler is a bit cranky, but seriously, hold out because the service people are amazing).
The job was scheduled really fast- a week!
On the day of installation, they called ahead of time, showed up and were incredibly respectful to my home and to me. They took their time doing the install, asking me whenever there were options to be discussed, making sure I understood the system, and repeatedly reminding me to call if I needed help or explanation after install.
Honestly, its the best service call I've had through the pandemic, possibly before that, too. I was very happy to pay their rate, which was very competitive (I'd have only saved $150 going with someone else, but it was clear they cared less).
Having talked to a TON of plumbers and other services, I was very happy with my choice.

Spare yourself a headache and use a different company, there's tons of plumbing company options way better than this one

Very accommodating - easy to work with. Dean explained every step and gave us more economical options too. Used them for our backflow inspection and a cracked pipe. Will use them every year for our inspection now. Eric was our technician and was very polite, professional and took his time and explained everything. Very trustworthy and honest.

I am a first time customer of American Backflow Services and I am so pleased with their service. The technician was very nice and friendly and called an hour before he came and was right on time!!!!!! That is amazing. I took a card from him and made sure to schedule us for next year! This was on a referral from a neighbor and he was so right when he told me that they did a good service and would get the paper work to the city of Newberg in a timely fashion. Thank you American Backflow Services. Diann P in Newberg,Oregon

We have used American Backflow Services for years now. They are GREAT! You can schedule online, pay online and they are on it! They send reminders every year and I just schedule, and DONE! Also, they offer great prices ($40) so it's just easy and reasonably-priced too. They send verification of their services to the city so it's just so efficient! I highly recommend American Backflow!

We used American Backflow again this year and were just as happy as the first time! They had us on a reminder schedule and even called me to schedule before I realized we were nearly due. SO HELPFUL. They were on time for the appointment, worked quickly so the water wouldnt be off for too long, and their online payment system is a breeze to go through.

I am VERY happy we found this company when we did because the process required by the city for these devices to be checked out every year is a little confusing, and American Backflow basically took it over from me and have handled everything needed for the last two years.
