What to Expect During A Backflow Test

  • Our tester will meet with your contact for the job and brief them.
  • We go through any necessary background or security checks before starting any job if you require it.
  • After finding the backflow device we make sure we have the right forms for any potential agreed upon tests.
  • A Backflow Test begins with various tools/gauges to check for any pressure changes in the backflow device.
  • If there’s nothing wrong with it, which in most cases there isn’t, the device passes.
  • When it fails, our testers open the device to clean out any debris that may be obstructing one of the valves. We have found tennis balls, wood 2x4s, rocks the size of your hand, a donut, and many more things in our days.

  • We are fully stocked with any parts that might be needed for the repair and can fix your device on the spot.

  • After opening a device the tamper switch needs to be reset once cleaned.
  • We always make sure to brief the owner of the property on what was done and upcoming visits before leaving.

Backflow testing cost twice as much as last year.... total misunderstanding. Customer service rep did not explain pricing. Talked to someone else and they explained what was going on. I have a lot of devices and I need to have them check annually so this is the best company to do it. I should have asked more questions.

I love this: The office makes an appointment, with an actual time range. Then the service provider calls to say they are on the way, during that time. And then texts you when they arrive. I made an appointment for our next annual backflow check - in 12 months!

I got quoted $240 then I got quoted $99 for the work and then I ended up getting charged $240. While the technician that came out was pleasant to work with, their back end office is a mess. They need to get their act right.

Our the backflow device annual testing was performed yesterday and Matt K was amazing. He communicated every step necessary and was able to efficiently work his way around without needing to be escorted every step of the way. I already received an email with the invoice and copies of the test results. I am super impressed and very happy. I love to get things off my desk asap, this is great. I highly recommend you contact Megan D. for any future testing.

This is the best backflow testing and certification we've experienced from start to finish in terms of cost and quality. We were able to schedule the work at a guaranteed time which was a first ever for a service call and was truly a day saver. Jack arrived even earlier but waited till the appointed time to ring the door bell. He was very professional, respectful, knowledgeable, efficient and a pleasure to work with. Besides Jack, all the staff we dealt with were wonderful. Being a family owned business, they treat their customers like family. We certainly highly recommend Chicago Backflow and will be using them for future plumbing needs!

Top notch service!!! We are a new to the area company that needed a portable RPZ to use on city of Chicago hydrants, the owner himself took the time to sit down with us and write down exactly what to get and where to get it. They also set up a prompt test date for it. Thanks again!

We used CBI for our backflow inspections. They were extremely responsive and quick to give us pricing. The technician, Mark, was on time, professional, quick, efficient and able to answer many question I had about our specific devices. Couldn't have asked for a better experience. CBI had much better pricing than other companies in the area who we've used in the past. 5/5.

Chicago Backflow was very professional from the office staff to the onsite technician. The office staff provided a time-window and Genaro, the technician called early and showed up on-time.As a plumbing novice, I do not have much experience with backflows or plumbing. I highly encourage to opt for their $150 test/repair package instead of the standard $99 for first-time customers. It is slightly extra but if the backflow test were to fail, you might be quoted the standard price that will be substantially more.
