FAQs: Frequently Asked Questions

How often does the backflow preventer need to be tested and who should test it?

The backflow assembly will require an annual inspection by a certified tester. The City of Mount Shasta retains all past testing information and, as a customer service, can provide previous tester’s contact information. The City will mail an instructional letter and a Test and Maintenance Report Form approximately 90 days prior to the current expiration date of your backflow device inspection.

Failure to renew your valid test date can result in termination of your water service by the City.
