About Us
To maintain water quality throughout the distribution system, Cal Water implements a comprehensive cross-connection control program. This crucial safeguard prevents activities on customer properties from affecting the public water supply.
Our specialized team ensures all backflow prevention assemblies are tested annually, evaluates non-residential connections, and manages installation of new commercial and residential assemblies. Last year, our experts oversaw installation of 2,826 new assemblies and testing of 36,433 backflow prevention assemblies company-wide.
Customers play a vital role in preventing water system contamination. Even small home improvement projects can create potential hazards, so following proper plumbing codes is essential for maintaining community water safety. Always consult with a qualified plumbing professional when making changes to your water system.
Common cross-connection concerns include:
- Garden hoses without simple vacuum breakers (available at home improvement stores)
- Improperly installed toilet tank fill valves lacking required air gaps
- Landscape irrigation systems without proper backflow prevention assemblies on supply lines
