Backflow Assembly Tester

BAT Certification Renewal

Certified Backflow Assembly Testers (BAT) must renew their certificates annually by paying a renewal fee as specified in WAC 246-292-090. All BATs eligible to renew their certificates will receive a renewal notice from Washington Certification Services.

Renewals must be paid online by credit or debit card. Washington Certification Services no longer accepts renewal payments by check or money order. Renewal payments by check or money order received in the mail will be returned.

A first renewal notice is sent by email in November to the email address on record with Washington Certification Services. An email copy of the first renewal notice is also sent to the email address on record.

The first renewal payment must be submitted online by the deadline date listed on the renewal notice. Payments made online after the published first renewal deadline date will be subject to a late fee.

If payment of the first renewal notice has not been received by the deadline date listed on the renewal notice, a second and final renewal notice is sent by first class mail. The notice is sent to the home address on record with Washington Certification Services. An email copy of the final renewal notice is also sent to the email address on record.

The final renewal notice will include a late fee. Payment of the final renewal amount including the late fee must be made online by the last day of February.

The fee for renewal by the first renewal deadline is $42.00. A late fee of $35.00 is assessed on the second and final renewal notice for a total renewal fee of $77.00.

An employer may choose to pay a renewal fee for a certified BAT, however this is an agreement between an employer and an employee. Failure of an employer to pay the renewal fee for a BAT by the published deadline date will result in inactivation of the BAT certificate and is not eligible for appeal.

Renewals must be paid online by credit or debit card. Washington Certification Services no longer accepts renewal payments by check or money order. Renewal payments by check or money order received in the email will be returned.

After the renewal payment is processed a certification validation card for the renewal year is sent by first class mail to the address on record with Washington Certification Services. The validation card identifies an individual as a certified Backflow Assembly Tester in Washington.

Department of Health requires the home address as the address of record for a BAT certification. Business or employer addresses may not be used as a BAT certification mailing address.

It is the responsibility of the BAT to notify Washington Certification Services in writing of changes in address to ensure delivery of important certification notifications. Failure to do so does not constitute an excuse for waiver of the late fee assessment, failure to renew a certificate, or failure to demonstrate professional growth. Appeals will not considered from BATs who fail to report address changes in writing.

BATs have over three months to pay the annual renewal fee. During that time they receive at least two renewal notices by email and a second and final notice by first class mail. Failure to pay the renewal fee by the final deadline date is not eligible for appeal to Department of Health.
