Kevin O'LaughrinThe owner of GaugeTec and I have been teaching together for over fifteen years. Together we have helped certify over a thousand Wisconsin,Minnesota,Iowa and Illinois backflow testers. As a Cross Connection Control and Plumbing Code Instructor I would highly recommend GaugeTec to any of my students for their annual test gauge calibration needs. You will find that GaugeTec is very professional and always puts the customer first. Rest assured that your test gauge will be in good hands and returned to you promptly and in great shape.

John at GaugeTec provides excellent service that are hard to match! Tweet Garot relies on GaugeTec to keep our RP equipment certified and up to date.
Thank you!!

I have had many interactions over the past 20 years with John, Owner of GaugeTec. Although I did not receive my Backflow Testers certification thru John, I did attend a Surveyors course and have consulted with him regarding cross connection issues that my techs and I have encountered in the field. I consider him an authority on the subject of all things related to cross connections, and value his input.  GaugeTec is my instrument testing, repair, calibration and certification company and I am very confident my equipment is field ready and accurate.

It’s a joy to recommend GaugeTec services to our many clients and students. John offers professional quality – reasonable prices – and fast service for maintaining backflow prevention testing equipment. With his years of service in protecting the water- we can count on John to protect our test kits!!
