Received a Backflow Notice From Your Water District? Here’s Exactly What to Do

That letter from your water district is not a suggestion. Across Eastern Washington and North Idaho, public water systems require annual testing of backflow prevention assemblies so irrigation water, fertilizer residue, or other private-side water cannot reverse into the drinking supply. Miss the deadline long enough and many purveyors can escalate to shutoff warnings. The fix is simpler than it looks: once a certified appointment is on the calendar, districts typically stop the shutoff path for that notice — and at Liberty Lake Backflow we guarantee your water won’t be shut off over the notice once you’re booked. Then we complete the test and help file the pass.

Here’s a clear checklist if you just opened a backflow notice in Coeur d’Alene, Hayden, Post Falls, Rathdrum, Liberty Lake, Spokane Valley, or Spokane.

1. Read the letter carefully (don’t just panic-file it)

Pull out three facts and write them down:

• Due date — the date a passing test must be on file (or completed).
• Account / site ID — so the district can match your report to the right property.
• Assembly type or serial (if listed) — PVB, RP, DC, etc. Helps the tester find the right device.

If the envelope is from Liberty Lake Sewer & Water, City of Spokane, Modern Electric, Vera, Hayden Lake Irrigation District, City of Post Falls, Ross Point, or City of Rathdrum — the process is the same idea: test by a certified tester, then a report that satisfies your purveyor.

2. Confirm you actually have a testable assembly

Most residential notices are for the irrigation backflow preventer — often a pressure vacuum breaker (PVB) mounted about a foot above ground near the sprinkler shutoff. Some homes also have assemblies for fire lines, boilers, or pools. If you sold the house, removed the sprinklers, or never found a device, call the number on the notice before you book. They can update records; we can also help locate the assembly on site when you book with access notes.

3. Book a certified tester — sooner if the due date is close

Washington (WAC 246-290-490) and Idaho cross-connection programs require tests by qualified / licensed testers. Hiring a random handyman is how reports get rejected. Book with enough lead time that a retest (if something fails) still fits inside the window.

4. Be ready on test day

• Someone home if the device is locked, gated, or indoors.
• Gate codes, dog notes, and “left side by the AC” directions in your booking notes.
• Irrigation water available if the test needs system pressure (we’ll tell you if something blocks the test).

A typical residential visit is 15–30 minutes once we can reach the assembly. You should leave knowing pass/fail and next steps before we drive off.

5. Get the report filed — this is what “resolves” the notice

A green sticker on the device is not always enough. Your water system wants a passing report in their system. We help route paperwork for Liberty Lake, Spokane-area, and Kootenai County purveyors so you are marked compliant and stay off the shutoff list.

6. If the device fails

Failed tests are common on older PVBs (stuck checks, damaged air inlet, freeze damage). You need repair or replacement by someone qualified, then a retest. We show you what failed and outline honest options — no hard sell. Do not ignore a fail and hope the district forgets; the notice is not closed until a pass is on file.

What not to do

• Don’t wait until the week before shutoff — rush pricing exists for a reason, and schedules fill.
• Don’t assume “I turned the sprinklers off” exempts you — districts still track the assembly on record.
• Don’t send an incomplete report or the wrong account number — it delays compliance.

Bottom line

Notice → book certified test → pass (or repair + retest) → report filed. That sequence keeps your water on. If you want it on autopilot next year, ask about our Yearly Autopilot plan ($5 off standard each year, we reach out before the next notice season).
