About Us

PM Backflow provides prompt and cost effective backflow prevention testing, maintenance, and installation services for all residential, commercial, and industrial applications.  Founded in 2003, we have provided service under the simple premise that “just because it is required by law, that doesn’t mean it has to be difficult or expensive for the customer.”

Our goal is to make the process as simple as possible. We achieve this by providing the following:
• Ease of scheduling (web, email, or phone)
• Quick turnaround of test results with copies provided to the customer and their water provider
• Convenient payment options
• Option of automatic scheduling of annual retest
• Large group discounts
• One charge per assembly per year (if repair is required, retest is free)
• Nationally certified testers through ABPA
