Backflow test, annual

The annual backflow test on your irrigation assembly, done by a certified tester, with the report filed.

One flat fee to find out what is wrong. You are told it on the phone before anyone is dispatched, and it comes off the job if you hire us. Read our Plain Terms

What the work is

An irrigation system connected to the drinking water supply needs a backflow prevention assembly, and that assembly has to be tested annually by a certified tester. The notice you received is real and the deadline on it is real.

The test itself takes minutes. The parts that matter are that the tester is certified, that the assembly is protected from freezing, and that the report reaches the right place.

How residential reports are filed is something we have asked St. George Water Services to confirm in writing rather than assume. Until we have that answer, we will tell you exactly what we did with your report.

What is included

  • The test by a certified tester
  • The report, a copy to you
  • Filing it as the utility requires
  • Telling you whether the assembly is protected from freezing, and what to do if it is not

What is not

  • Repairing or replacing a failed assembly, which is quoted after the test
  • Winterising, which is separate
  • Testing an assembly we cannot safely access

What the notice is actually asking for

The guide below explains what that device does, why the city requires it, and what happens if the test is late. It is written from the city's own requirement rather than from a testing company's marketing.

What to ask anyone quoting this, us included

  • Who is the certified tester and what is their number?
  • Where does the report go?
  • Is my assembly protected from freezing?

What we can show you in writing

Every line traces to a document we read in full. The number after a sentence points to the research below.

  • St. George requires an approved backflow assembly on every outside watering system, protected from freezing, and tested annually.1
  • The obligation is the property owner's, in the city's own words, under St. George City Code Title 8 Chapter 2.1
