Recommended Customer Reviews

I received other quotes from other companies but Backflow Northwest response time and price was great. I was able to make an appointment within a day or two. Our technician was Scott R who is awesome. We are new to the area so Scott explained the reason for the test. He was very professional and did not mind answering any of my questions. The testing was really quick. They send the report to the water company as well. So, the only thing I had to do was make an appointment and pay. We will definitely use Backflows Northwest/Scott for our annual testing. I will definitely spread the word to my neighbors since this is a newer neighborhood. Thanks Scott R for great customer service.

Backflows Northwest were timely and super-responsive! And they showed up within the 2-hour window and completed 4-backflow-tests and were finished within 1-hour. We are now on an annual program with them!

I first contacted Backflows Northwest via their online scheduling system. After a few days with no response I decided to call and schedule. This was 18 days before my testing was due, so I was scheduled for ""sometime in the next two weeks."" After 14 days of receiving no indication that testing was done, I called and was told that I had been scheduled the previous week but due to an emergency with another customer my testing was not performed. I had not been automatically rescheduled. Since my deadline was approaching, they offered to schedule me ASAP and file an extension with the water company on my behalf. After three days with no evidence of testing, I called the water company and was told no extension had been filed.
At this point I called again to cancel my service request. Bottom line, make sure you are given an actual date for service.
I was very happy with the ease of scheduling, the fact that I didn't have to be home for testing, and the friendly folks I spoke to over the phone, but lack of follow through is very disappointing.

I've gone thru BN for the last two years, and will continue to do so. Their promptness and ease of service (you're not required to be home) is great for a busy schedule! The first time I wasn't home and they left the results at my door, the second time they came I wasn't feeling well and wasn't disturbed at all, they came, did the test, left results, and that's it! Easier the better when it comes to getting things like this done, especially with a very random schedule. They also have great customer service and work with you to make sure it's done quickly. After dealing with a couple other places that I was less than impressed with I will continue through BN as long as I need backflow testing! Thank you for a great experience!

Great customer service! Easy appointment process, they do what they say and with the bonus of with a smile. Thank you. It's nice to find companies that care about results and the customer !

These people were incredibly accommodating and their customer service is top notch. I totally botched the process of having my backflow device inspected and they really saved me. It was the first year in our home and I didn't know we even had a backflow device or that they were required to be inspected. I was late on it, because I didn't pay attention to the date, then mistook a pressure device in our basement for the backflow device, had to reschedule twice and then got a notice that my water was going to be shutoff if I didn't do it asap and they came on a Saturday to take care of it. Basically, I was a terribly inconvenient customer and they were nothing but kind and understanding.

This firm is very professional and prompt. You can sign up for an annual backflow test and not have to worry about it each year. They have a quick response time and are very courteous. The fee appears to be in line with other companies and I appreciate that.

Backflows Northwest responded to my online backflow test request quickly. Their technician caught a small leak of my irrigation system. The technician fixed the leak on the site and the customer service explained the leak and fix in details to me. I was very happy with their service.

Based on a failed test by our annual tester, he recommended that we replace our backflow assembly because of the age of the device. After having another company not show up and chalk it up to a ""misunderstanding"" about the date, I contacted Backflows Northwest. I spoke with Steven who discussed possible repair or replacement of the assembly. We scheduled an appointment for Tim to come out on Saturday morning of the Memorial Day weekend. Tim arrived at our house promptly before 8 am and after glancing at the device, didn't think it looked that bad. He suggested testing it and it passed! He saved us hundreds of dollars and gave us back several hours in the day.
We truly appreciate Tim's honesty and genuine concern for his customers. He is a standup guy and a tremendous asset to the company. We wish all technicians are like Tim!

Terribly RUDE and irresponsible company. try to avoid. wish there were 0 stars option.
so back in April, it was time to annual back flow test, we scheduled one with them, asked them what they need from us. they told us they will take care of everything, we don't even have to be at home for the test. that's great right?
then in may, we got a notice from the city saying we did not finish our back flow test, so I contacted them again, didn't answer the phone. then I contact the city, and was told I had two irrigation and fire sprinkler back flow tests, and the fire sprinklers were not tested.
I was confused and called the company again, without giving out any of my info, I asked if they'd take care of everything, the operator said yes, they will take care of everything for $45. then I specifically asked, if they would take care of the irrigation and the fire sprinkler test as well, she assured me again, they will take care of everything for $45. it was Thursday and the deadline from the city was 4pm next Tuesday, so I told her the situation and ask for a test before that, she said she couldn't. well, then I told her to get a supervisor and finally we had an appointment down on Tuesday 10AM. at this point, I was OK because everyone makes mistake right?
then it comes to 10AM Tuesday, the technician came to knock my door, I opened the door and he said he's testing the back flow, I said ok and went back to grab my glasses, when I came back out (within 2 minutes), he's gone, without asking what I have and without entering my garage (where the fire sprinkler thing is). hey, I scheduled this test just to test fire sprinklers, and you left without even asking or looking at it? seriously? then I called the company third time, and thankfully the technician came back later in the day. ok I had to stay home for this long, but at least our water won't be shut off.
the above is irresponsible part and here comes the rude part.
I received a second invoice asking for another $45 for ""annual testing of back flow assemble"". I thought it must be a mistake because we have paid for the first invoice $45 before they even came back. so I called them, again. and they still asked me to pay for this $45, well, what about ""$45 dollars we take care of everything""? guess what, operator defined 'everything' for me, she said, 'everything' means 'everything from trip fee, filing fee, paperwork fee, etc', and irrigation is not in 'everything' for fire sprinkler, and fire sprinkler is not 'everything' to irrigation, and we do this for 'everyone', so I guess we might have a different understanding on 'everyone' right? because I asked couple of my neighbors (same development, same builder, all built within last 12 month), they all finished the test for $45. at this point, the women on the phone was being rude already, won't even let me speak, won't let me finish my sentences. I didn't want to argue on the phone, so I just said, if we come down to business next year, I'll pay $90, but this year, I asked for a quote, you give me $45 without asking how many devices I have, just plain said $45 for everything, it's you mistake, I'll not pay $45. guess what, she said, ""if you don't want to pay $45, fine, I'll write it off. but I'll note on your account, bad customer, we will never do business with you again"", and she hangs up immediately.
yeah, I guess finally we can be on the same page, I will never do business with you too.
