What should I check before scheduling a tester for City of Westminster Cross-Connection Control and Backflow Program?

Confirm the due basis, property type, device type, and submission method before booking. Then confirm tester eligibility directly with the utility or portal, and make sure the report can be filed through the required utility or portal path.

What costs or portal fees should I expect for City of Westminster Cross-Connection Control and Backflow Program?

Testing is market-priced, but Westminster's broad service scope makes the real cost question whether the city has required protection on the line. Repair and retest costs rise with larger irrigation or fire line assemblies.
