Posted on James FitzgeraldTrustindex verifies that the original source of the review is Google. Right from the start top to bottom this is a great company to work with. Sara is very upbeat, and will remember you even after a year or two. 100% we would recommend simply backflow. I am a general contractor so I know the difference between great, good & bad and they are great.Posted on Carl D wertsTrustindex verifies that the original source of the review is Google. Simply Backflow has been my plumbing partner for over 10 years. Minas has unquestionable integrity and quality consciousness to be sure the project is done right. He totally stands behind his service and will happily return if any adjustment may be needed. In this day it is such a relief to be able to work with someone you can completely trust to do excellence at a fair fee.
