Backflow services in Snohomish

Who is your water purveyor in Snohomish?

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

Farm and acreage properties often combine public water with stock tanks, barn plumbing and fertilizer injection on irrigation lines, and every one of those is a cross-connection. We'll walk the property with you and recommend protection that satisfies your purveyor without overbuilding.

Snohomish backflow FAQs

Do farm and livestock water lines need backflow protection?

Usually, yes. Stock tanks, chemical injection on irrigation and barn plumbing can all create cross-connections, and purveyors commonly require a reduced pressure assembly or an air gap for those uses. We'll look at your setup and recommend what fits.

Do you cover Clearview and Cathcart?

Yes, along with Three Lakes and other unincorporated areas around Snohomish, as long as the property is on a public water system with a testing requirement.
