Were you a Rick Hanson customer? Rick has retired from backflow testing and has endorsed Advanced Backflow Solutions to take care of his former customers in Edmonds, Esperance and Shoreline. We'll keep up the same one-on-one service. Book your test online or give us a call.
Shoreline sits just south of the county line, about 10 minutes from our Edmonds base. We test residential assemblies from Richmond Beach and Innis Arden to Ridgecrest and North City, and commercial assemblies along the Aurora Avenue corridor.
With two light rail stations open and a wave of townhome and apartment construction around 148th and 185th, we also install and certify new assemblies for builders working to tight inspection schedules.

Who is your water purveyor in Shoreline?
Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Shoreline properties are commonly served by Seattle Public Utilities or North City Water District.
Not sure which one is yours? Check the top of your water bill or the test notice itself. Or just give us your address when you book and we'll figure it out and send your report to the right place.
Local know-how
Older Shoreline homes often have irrigation added years after the house was built, sometimes without any backflow protection at all. If you're not sure whether your sprinkler system has an assembly, we'll check and tell you honestly whether you need one.

Shoreline backflow FAQs
Does Shoreline get its water from Seattle?
Much of Shoreline is served by Seattle Public Utilities, and parts of east Shoreline are served by North City Water District. Either way the annual testing requirement is the same, and we'll send your report to the right place.
Do new townhomes need a backflow test before move-in?
New assemblies have to be tested when they're installed, before the purveyor will sign off. If you're a builder or developer, we can test and certify on your timeline so inspections don't hold up closing.
