According to Texas Health and Safety Code, when must a Customer Service Inspection be performed?

A Customer Service Inspection must be performed when there is reason to believe that cross-connections exist. This is crucial for the protection of the public water supply. Cross-connections can pose significant health risks, as they can allow non-potable water or contaminants to enter the drinking water system. The inspection ensures that appropriate backflow prevention measures are in place to safeguard the water quality.

Addressing potential cross-connections is a proactive measure in maintaining safe drinking water standards. Other situations, such as leaks in plumbing or requests by customers, might warrant inspections but are not specifically mandated under the Texas Health and Safety Code in the same way. Similarly, the installation of new water meters does not inherently require a Customer Service Inspection unless there are concerns about cross-connection or other safety issues. Thus, identifying and addressing cross-connections takes precedence in the regulatory framework to ensure public health and safety.
