Who checks cross-connection facilities once they are installed?
All back-flow prevention tests must be performed by state certified companies. The tester needs to provide a certification report to the District. Contact Chic Nessly, Customer Service Team Leader at (425)392-6256 x213 for the latest District compliance standards for cross-connections. A list of companies commonly used within the District is available to the public. Contact the Billing department for further information on the latest list.
