Backflow Testing in Mill Creek, WA
State-certified backflow testing, repair and installation for Mill Creek homes, HOAs and businesses, with your test report filed with your water purveyor for you.
- WA-certified testers
- Reports filed for you
- 24/7 emergency dispatch
Mill Creek's planned neighborhoods, HOA-maintained common areas and golf-course landscaping add up to a lot of irrigation backflow assemblies, and a lot of annual due dates that tend to land around the same time.
We work with individual homeowners and HOA boards alike. For associations, we can test every common-area assembly in one visit, file each report and send the board a single summary showing what passed, what failed and what it will cost to fix.
Backflow services in Mill Creek
Who is your water purveyor in Mill Creek?
Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Mill Creek properties are commonly served by Alderwood Water & Wastewater District or Silver Lake Water & Sewer District.
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
Town Center's restaurants and shops, plus the medical and office buildings along the Bothell-Everett Highway, rely on reduced-pressure assemblies that can't be allowed to lapse. We keep a calendar for commercial customers and reach out before the purveyor's notice does.

Mill Creek backflow FAQs
Can you handle all the backflow assemblies for our Mill Creek HOA?
Yes. We'll inventory every common-area assembly, test them in a single visit, file each report with the purveyor and give the board one summary. Next year we'll reach out before anything comes due.
When should I winterize my irrigation backflow in Mill Creek?
Before the first hard freeze, which in south Snohomish County usually means late October or early November. Shut off the irrigation supply, open the test cocks to drain the assembly, and insulate anything that can't be drained. Our winterizing guide walks through it step by step.
