Issaquah runs from historic Olde Town and the retail corridor along I-90 up to the planned neighborhoods of the Issaquah Highlands and Talus. Corporate campuses, medical offices, restaurants and hundreds of HOA-maintained irrigation zones mean a steady schedule of backflow testing.

We test, repair and install assemblies across Issaquah and file each report with the right purveyor.

Who is your water purveyor in Issaquah?

Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Issaquah properties are commonly served by the City of Issaquah or Sammamish Plateau Water.

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.
