  3. VERIFY & ADD NEW ASSEMBLIES: Any new backflow prevention assemblies (not replacements) installed or tested need to have their locations verified by the City of Cedar Hill and tested by a licensed and registered backflow assembly tester. New installations may require a Plumbing Permit with the Building Inspections Department located at Development Services (285 Uptown Blvd. 2nd Floor). The backflow tester who performed the test will register the new backflow prevention assemblies into BSI Online. Contact Gregg Kidd at 972-291-5126 x2805 or via email.

What is Backflow?

Backflow is the undesirable reversal of the flow of water or mixtures of water and other undesirable substances from any non potable water source into the distribution pipes of the potable or drinking water system. Backflow occurs as a result of a “cross-connection” within the water system.  A cross connection exists when there is an actual or potential connection between a potable water system and any non potable source or system.  When a cross connection exists and backflow occurs, the water system can become contaminated and potentially very harmful.

For this reason the City of Cedar Hill requires that all backflow devices be registered with the Public Works Department and that the devices be installed and tested annually by registered, State licensed backflow testers.
