BackflowNear Test-Due Reminder

Certified backflow testers in Massachusetts

From the Massachusetts Department of Environmental Protection list of certified backflow assembly testers, read October 7, 2026. The state lists individual testers, not companies, so we show them by town.

978 testers with a current certificate

What Massachusetts's roster shows

  • 978 certified testers on the list, 978 with a current certificate.
  • The list names certified people with a work phone, not companies, and does not say who tests for the public: some work for water departments. Ask whether a tester takes outside work. The state prints it as valid on April 7, 2026. 129 testers on it are based outside Massachusetts and are not listed by town.
  • Most certified testers are based in Plymouth (18), Brewster (12), Boston (11), Worcester (11), Chelsea (10).

Questions

How do I check that a backflow tester is certified in Massachusetts?

Massachusetts Department of Environmental Protection keeps the official list of certified backflow testers. Every business on this page comes from that list as we read it on October 7, 2026; each listing shows the certificate number, and you can confirm it on the state's own page.

How many certified backflow testers are there in Massachusetts?

The Massachusetts Department of Environmental Protection list shows 978 certified backflow testers. It names people, not companies, and does not say who tests for the public, so ask a tester whether they take outside work.

How often does a backflow assembly need testing?

Most water utilities require testable backflow assemblies to be tested at installation and then every year, and some test more often for high-hazard sites. Your utility's notice gives your deadline and how to file the report.

Never miss your annual backflow test

Most water utilities require the backflow assembly on an irrigation, fire or commercial line to be tested every year, and a missed test can mean a shutoff notice. Tell us when yours was last tested and we'll text you a month before it is due, with certified local testers ready to book.
