FAQ

Questions, answered

Is backflow testing required?

In most cases, yes. Your local water authority requires the backflow assemblies it oversees to be tested on a set schedule — often once a year — and tracks the due date for each device.

How often do I need a test?

Usually once a year — your water authority sets the schedule, and each assembly typically comes due about twelve months after its last passing test.

Do you file the results for me?

Yes. After the test we submit your results to your local water authority and send you the certificate, so you don't have to chase the paperwork.

What happens if I miss my due date?

An overdue assembly can lead to non-compliance notices from your water authority. We send reminders as your date approaches so it doesn't slip.

Which assemblies do you test?

The standard field-testable backflow assemblies — RP, RPDA, DC, DCDA, PVB, and SVB — across fire-sprinkler, irrigation, domestic, boiler, and pool systems.

What does it cost?

Pricing depends on the number and type of assemblies at your property. Request a test and our office will confirm the details with you.
