Mountlake Terrace borders Edmonds, so it's one of the quickest trips on our schedule. We test backflow assemblies for single-family homes around Lake Ballinger and Terrace Creek, and for the growing number of apartment and mixed-use buildings in Town Center.
With the light rail station open and new construction going up around it, we also install and certify new assemblies on domestic and fire lines for builders who need a passing test before the water purveyor will sign off.

Who is your water purveyor in Mountlake Terrace?

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.

Mountlake Terrace backflow FAQs
How often do backflow assemblies in Mountlake Terrace need testing?
At least once a year, plus any time an assembly is installed, repaired or moved. That's a Washington State drinking-water requirement, and your purveyor will typically mail a notice when your test is due.
Do you test fire sprinkler backflow assemblies?
Yes. Fire lines usually use a double check detector assembly (DCDA) or reduced pressure detector assembly (RPDA). We test them alongside your domestic assemblies and coordinate with your fire-sprinkler or monitoring company when the system has to be taken offline.
