Course was very very informative and was extremely eye opening. R M  Greenleaf, Idaho

The course was informative and well put together. L S  Hayden, Idaho

This course was very informative and enjoyable. VERY fun instructors that know their stuff. Was tough class but the teachers made it fun and tried to make it less stressful. J W Twin Falls, Idaho

AWESOME CLASS! Thanks for making it fun, and making it easy to learn. I really enjoyed the relaxed classroom and comfortable environment you create! It makes learning fun! THANKS!! - A W / Kimberly, 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 a lot 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
