What type of Backflow Prevention Assemblies must be installed?
The Texas Commission of Environmental Quality (TCEQ) requires different types of Backflow Prevention Assemblies to be installed based on whether the assembly is protecting against a non-health or health hazard. A health hazard is one which could cause illness or death and must always be protected by an air gap or reduced pressure backflow prevention assembly. Non-health hazards may be protected by other less protective assemblies (e.g. double check valves, atmospheric vacuum breakers, etc.). A list of common hazards and the assemblies required by the Texas Commission on Environmental Quality rules 30 TAC 290.47 (i) Appendix I can be viewed by checking [Here]. This list and other information concerning the customers operations and plumbing are taken into consideration by the Citys Building Inspection Division as they determine the type of assembly required.
