Is Cal Water responsible for plumbing leaks?

The California Division of Drinking Water only authorizes Cal Water to take responsibility for the water system on the utility side of the water meter. Customers are responsible for maintaining the plumbing on their side of the meter, as illustrated in the below diagram.

Cal Water’s affiliate CWS Utility Services has contracted with HomeServe to offer optional insurance coverage for residents’ plumbing. For details, see the insurance page on this site.
