Our History

Over the years, Wednesday developed and implemented backflow prevention programs in her water purveyor role. This experience has allowed her to learn and understand why backflow preventers are needed and why they are so important.

She has a love for protecting our drinking water—so much that she created a residential backflow model to provide demonstrations on how easily backflow can occur in a home. She continues to look for ways to help educate and inform people on backflow prevention.

Today she is happy testing backflow preventers and educating clients.

She belongs to the Western Washington Cross-Connection Prevention Professionals Group and holds certifications through IAPMO ASSE International as a Cross Connection Control Surveyor, Tester and Program Administrator.
