About us
Dedicated to safeguarding your water supply. We’re a local, owner-operated team of certified professionals providing expert backflow prevention for homes and businesses from Mount Vernon to Tacoma.
Our story
Advanced Backflow Solutions is owned and run by Nicholas and Shelby Giroux. Nicholas leads the field crew; Shelby runs projects, scheduling and the relationships that keep property managers and HOAs coming back. Jeff Anderson keeps permits moving so installations never stall at the counter.
When longtime local tester Rick Hanson retired, he endorsed us to look after his customers in Edmonds, Esperance and Shoreline, and we’re proud to carry on that same one-on-one service.
We started the company with a simple idea: backflow testing shouldn’t be confusing or stressful. Show up when we say we will, test accurately, explain the results in plain English, file the paperwork, and leave the site cleaner than we found it.
With a focus on safety and purity, we specialize in maintaining the integrity of your water system, and every assembly we test is a small part of keeping the public water supply safe for everyone downstream. We take that seriously.

What we stand for
State-certified backflow assembly testers using accuracy-verified equipment and standard test procedures, every time.
We file every report with your purveyor and send you a copy. You shouldn’t have to chase anything.
Clear quotes before any repair, honest advice on repair vs. replace, and no surprise invoices.
We confirm appointments, show up in the window we give you and call if anything changes.
Boots covered indoors, landscaping put back, and water shut off only as long as needed.
A 24/7 emergency line, because assemblies don’t fail on a schedule.
