Granite Falls is the gateway to the Mountain Loop Highway, and most properties around it are larger lots and acreage with lawns, gardens, shops and outbuildings. Irrigation and outbuilding plumbing are the most common reasons we test here.

We schedule Granite Falls alongside our Lake Stevens and Arlington appointments, and file every report with your water system.

Who is your water purveyor in Granite Falls?

Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Granite Falls properties are commonly served by the City of Granite Falls or Snohomish County PUD.

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

Properties that combine a private well with a public water connection need special care: the two must be completely separated or protected, because well water can't be allowed to mix into the public supply. We'll look at your setup and recommend the right fix.

Granite Falls backflow FAQs

Is Granite Falls too far out for you?

No. We cover Granite Falls on the same days as Lake Stevens and Arlington, about 40 minutes from our Edmonds base.

I have a well and public water. Do I need backflow protection?

If both sources connect to the same plumbing in any way, yes. It usually has to be complete separation, an air gap or a reduced-pressure assembly. We can check your setup.
