What we handle

Got a county notice? We handle the whole thing.

If a letter showed up from Fairfax County saying your backflow assembly is due for testing, you're in the right place. It's a routine annual requirement — and we make it painless.

We're certified testers. We test the assembly, fill out the paperwork, and file the report with the county on your behalf. You don't chase forms or deadlines — we handle it.

Backflow FAQ

Questions homeowners ask.

I got a backflow notice — what do I do?

Send it our way. We schedule a certified test, run it, and file the results with the county for you. The whole thing usually takes about 30 minutes on site.

How much does a backflow test cost?

A standard residential irrigation test is a flat, affordable fee. If the assembly fails, we quote any repair before doing it.

What happens if I ignore it?

The county can apply penalties or shut off the affected service. It is far cheaper and easier to just get it tested — which is exactly what we handle.
