When the test is due
Each assembly has its own due month. Have it tested during that month every year. If you are not sure which month is yours, call the EWEB backflow program. A new assembly is tested when it is installed.
Notices: EWEB sends a reminder letter about the yearly test. The letter has a VCC number that starts with EWEB5. You can enter it in EWEB's backflow customer portal to see your assembly and past test reports. If you sign up for the Good as Gold program and name a yearly tester, the reminders go to that tester instead of you.

Finding a tester
Hire a tester certified by the Oregon Health Authority. EWEB posts a partial list of local testers. Prices vary, so get a few quotes, and not every tester does repairs. Homes hire a tester directly. Businesses can also ask EWEB to set up the test through an online form. The tester's fee is then added to your EWEB bill. The Good as Gold program lets you name a yearly tester who gets your reminders and books the test.
