Service area
Backflow testing from Mount Vernon to Tacoma
From our base in Edmonds we cover 39 cities up and down the I-5 corridor, across Skagit, Island, Snohomish, King and Pierce County. Pick yours for local details, including which water purveyors serve it.
Edmonds in the middle
One local crew for the whole I-5 corridor
We’re based in south Edmonds, minutes from I-5, I-405 and Highway 99, right in the middle of the region. Cities near home get the most flexible appointment times. For Skagit County, the South King valley and Tacoma we run regular route days, so give us a few times that work when you book and we’ll fit you into the next trip.

Don’t see your city?
We probably still cover it
We regularly work beyond the cities listed here, especially for commercial properties, HOAs and multi-property portfolios. Wherever you are, we’ll figure out which purveyor serves your address and file your report with them.
