The instructors are amazing. It is truly a pleasure to be in this class. A very stressful pleasure. A pleasure nonetheless. - J L / Spokane, WA


WOW! WOW! WOW! That was an intense week! Did not think anyone could make me feel so smart. Now I will see if I can keep this all in my head. - J M / Salt Lake City, Utah


Didn't know there was so much to learn about preventing backflow and how important it is. Now I see cross connections I have not noticed before. Glad I took the class. Thank you for your instruction. - B W / Idaho Falls, Idaho

​Great instructors, great idea to have 3 different instructors.  - M M / Twin Falls, Idaho


Class was fantastic! A little over whelming but the instructors were very patient and helpful. - M L / Post Falls, Idaho


I wish this class was more than a week long. A lot of information to get in your head in just a few days. The instructors made the class fun and I liked that they would stay during lunch and after class to help me. - J S / Kearns, Utah


OMG! I had no idea what I was in for. This was hard but the instructors made it fun and provided great encouragement. M W / Meridian, Idaho


I really enjoyed taking this class. I have been certified in Utah for over twelve years and found this to be the most informative training in backflow testing I have attended. Learned alot of things this old dog didn't know. GREAT CLASS! - C P / Salt Lake, Utah


NOT easy but I am so glad I took this class. I had no idea how much there was to learn about backflow prevention and testing. Super Duper instructors! They made it fun even though it was stressful. - S T / Twin Falls, Idaho
