Lake Stevens — Lake Stevens, WA
Backflow Service in Cavalero Hill
Cavalero Hill sits in southwest Lake Stevens — on the city's zoning maps, annexed in 2009, and built out with newer subdivisions on elevated lots. The homes here tend to be larger and owner-occupied, many in planned communities near Stonebriar, with the 20th Street SE corridor bringing steady mixed-use growth and Cavalero Hill Park's 35 acres anchoring the neighborhood.
Newer landscaped lots mean one thing for backflow: irrigation. Most Cavalero Hill homes with sprinkler systems have a pressure vacuum breaker on the side of the house, and every one of those assemblies owes Snohomish County PUD an annual test at the owner's expense. If you need backflow testing in Cavalero Hill, FlowGuard covers the neighborhood — testing, certification paperwork, repairs, and new installs.
For new buyers in the neighborhood: ask the seller for the most recent test report as part of your paperwork. It tells you the assembly type, its condition at the last test, and when the next one is due — useful information that costs you nothing to request.

Cavalero Hill Backflow Notes
What we see most in Cavalero Hill: newer PVB assemblies on irrigation systems, installed when the subdivisions went in. They're the standard residential setup — reliable, but still due for their annual test, and still vulnerable to the two things that take assemblies out: worn internals with age, and freeze damage in an exposed spot.
Most of these devices went in during the 2000s and 2010s, which puts them in the prime of their service life — old enough to need their annual check without fail, young enough that rebuilds are rarely necessary. The main thing Cavalero Hill owners get wrong is assuming a newer assembly doesn't need testing. It does — the PUD's annual requirement applies from the first year, not the tenth.
- Newer subdivisions, high irrigation likelihood. Landscaped lots almost always mean sprinklers, and sprinklers mean an assembly — check the side of the house or the valve box near where the irrigation branches off.
- Elevated lots. Cavalero Hill's terrain puts some assemblies in exposed positions; an insulated cover is cheap insurance against the freeze-crack failures that show up every spring.
- Growth corridor. With the 20th Street SE corridor still developing, new installs are common — every new PUD service with irrigation needs its initial test upon installation, then annual testing after that.

Cavalero Hill — FAQs
I just moved to Cavalero Hill — how do I know if I need backflow testing?
If your home has an irrigation system — or a pool, boiler, or similar cross-connection — the answer is yes. Look for a brass assembly (usually a pressure vacuum breaker) on the side of the house or in a valve box. Snohomish County PUD requires annual testing at the owner's expense for every assembly protecting the public system.
Where is the backflow assembly usually located?
Near where the irrigation line branches off your water service — commonly on an exterior wall or in a ground-level valve box. A pressure vacuum breaker must sit at least 12 inches above the highest point of irrigation piping, so they're often visible on the side of the house.
Do new-construction homes need testing right away?
Yes — the state requires a test upon installation, with the report filed to the PUD. After that, the annual cycle begins. If your builder handled the install, confirm the initial test report was filed; then calendar the annual test from there.
Which other neighborhoods do you serve?
All of Lake Stevens and surrounding Snohomish County areas — including Frontier Heights, North Lake Stevens, Soper Hill, and South Lake Stevens. See the full list on our areas served page.
Are there many backflow assemblies in Cavalero Hill?
Yes — it's one of the higher-density areas for them. Newer subdivisions with landscaped lots mean most homes have irrigation, and irrigation means an assembly. If you're new to the neighborhood, assume yours needs its annual test until a filed report tells you otherwise.
