The City of Grapevine’s Backflow Prevention and Cross Connection Control Program aims to ensure that the public water supply is free of contaminants and that potable water remain safe for the public.

As required by state and federal law, existing systems and new installations must be inspected by the City of Grapevine’s Development Services Department and the Public Works Department.  To this goal, all annual backflow testing companies and installers must be certified by the state and city of Grapevine and backflow testing licenses must be kept current.  For more information call 817-410-3165.

City Backflow Testing is a licensed backflow testing company and has been testing backflow device for quite a few years now.  For affordable backflow testing call City Backflow Testing.
