Backflow testing in
Williamsburg & James City County


Certified testing for every assembly on the property: domestic and main-supply, irrigation, pool and spa fill and process equipment. The report goes to your water provider, and the record stays on file for you.

Your water provider

City of Williamsburg · James City Service Authority

Inside city limits it's the City of Williamsburg; most addresses outside are James City Service Authority (JCSA), which charges a filing fee per assembly that we pass through at cost.

What each provider requires

Around Williamsburg & James City County

We confirm which provider serves the property before the visit, since a Williamsburg mailing address doesn't settle it.

Commercial, hospitality, HOAs, irrigation and homes.

Requirements are set by the water system that serves the property and can change. Confirm current requirements with your provider before relying on a date.

How it works

Scheduling hasn’t opened yet. This is how service will run once it does.

1 · Tell us the deadline

From the notice, the last report, or the date on the tag. Not sure? Send a photo.

2 · We plan your window

Once scheduling opens, we’ll offer a window ahead of the deadline and route Williamsburg & James City County together so nobody pays for a one-off drive. Need it sooner? Ask for a tighter window.

3 · Tested and filed

We’ll test every assembly on the property in one visit, submit the report to the City of Williamsburg or James City Service Authority where it accepts tester submissions, and post a copy to your customer portal.

Assembly Watch

Enroll once and we carry the calendar: each assembly tracked against its water provider’s deadline and testing requirements, including additional tests when they apply, a heads-up before it’s due, the test, the filing where the provider accepts tester submissions, and the record kept for owners, inspectors, insurers and buyers.

Not sure who to call or what is due?

Tell us where the property is and what is on it. Sorting out which provider governs it and what they require is the first step of every account we take on.

Scheduling hasn’t opened yet. Sending an inquiry puts you on the testing list; it doesn’t book an appointment. We’ll follow up by email.
