Best Backflow Assembly Testing in Seattle WA

Spoke with Simon on Thursday morning and that afternoon he was on site discussing my options with me regarding a main line water leak. He advised what his work involved and what the cost was, then he proceeded to perform his detection work. Within 30 - 45 minutes he was able to determine the exact location of the leak, and that was confirmed by the plumbing company, Maple Valley Plumbing, when they repaired the leak.
Simon was very helpful and kind in his work and support with costs. I am grateful to him for his help and his referral to Maple Valley Plumbing too. Everything was completed expediently and efficiently. Thank you.

Mac has done the backflow testing for my house in Shoreline for the past 3 years. Scheduling my backflow test has been easier that with other testers I've used in the past. He has always been on time to the appointments I've made via his website.

I've had him conduct two backflow inspections during this pandemic and he has been very careful in regards to wearing a mask both times. (Really appreciate this!)

On the day of testing, he submitted the reports required by the city of Seattle via email and cc'd me.

Good Guy Backflow works well for me.

We use Ben every year for our backflow assessment. He is always on time, thorough and easy to get in touch with! We look forward to seeing him every year!
