"GREAT SERVICE - Requested Service Call from Andrew [with County Backflow]. *Actually, he was referred to us by another serviceman that recently retired. *Andrew was prompt, courteous, on time and fulfilled all the requirements necessary for our business in servicing three preventers. A great 'people' person. He took the time out to answer any questions I had and was able to provide any recommendations for future (annual) visits. When finished, he was clean, 'detailed' and removed any debris in the surrounding area of his work. Looking forward to his next visit. * FIVE STARS in my opinion. *"
"Andrew from County Backflow performed testing recently, and his services were excellent. He answered my calls with politeness, flexibility, and responsiveness. He completed the testing far in advance of the scheduled time and turned in the testing paperwork well ahead of the deadline. I'm quite happy with his service and will be using his service in future as well."
"5 stars. Quick response and Andrew from County Backflow got my problem solved fast. Will be using again in a year."
