A Consumer's Guide to Backflow Prevention in Texas
The Texas Commission of Environmental Quality requires all public water systems to maintain a cross-connection control program that protects the distribution system delivering drinking water to your home or business.
City of Tomball's cross-connection control program includes:
- An inspection of the customer's private plumbing to identify and prevent cross-connections and potential contamination, including contamination from high lead levels in the plumbing.
- Installation and testing of backflow- prevention assemblies, where required.
- Rules to prevent cross-connections and unacceptable plumbing practices- ordinances, regulations, service agreements, and a plumbing code.

Some Public Water systems may have more stringent requirements that the TCEQ. TCEQ regulations are the minimum requirement.
How can backflow be prevented?
Backflow into a potable-water system can be prevented by using a backflow-prevention assembly, or an air gap, which is a physical separation between the water supply and a potential source of pollution. Licensed professionals as well as your public water system are responsible for determining the type of backflow- prevention assembly required, based on the degree of hazard.
Testing backflow- prevention assemblies
Because backflow-prevention assemblies are mechanical assemblies that can fail, the TCEQ requires testing of all backflow-prevention assemblies at installation by a TCEQ-licensed tester. Backflow-prevention assemblies installed to protect against any health hazard must be tested annually.
