How backflow testing is done properly

Backflow Testing & Certification is handled by independent licensed plumbers in Utah. This page covers what the work involves, what changes the price, and the Utah code and permit rules that apply. Published ranges are on the separate backflow costs page. Locally, the biggest markets for it are Salt Lake City, West Valley City, Provo. Requests for it often arrive alongside drain cleaning & clogged drains.

  1. The assembly type, size and serial number are recorded
  2. Water is temporarily isolated for the test sequence
  3. Differential pressure and check valve performance are measured
  4. Failed assemblies are rebuilt or replaced
  5. The report is filed with the water purveyor by the certified tester

Before you sign

Questions to ask before authorizing backflow testing

  1. 01

    Is the tester certified with the local water purveyor, because reports from uncertified testers are rejected and must be redone?

  2. 02

    Who files the completed report with the purveyor, and by which annual deadline, since late filing can trigger penalties?

  3. 03

    How many assemblies exist on the property, and are irrigation, fire line and boiler devices all included in the visit?

  4. 04

    If the assembly fails, is a rebuild kit carried on the truck, or does a second visit become necessary?

Coverage

Where backflow is requested in Utah

Answers first

Backflow in Utah — you asked

Why do I have to test my backflow preventer every year?

Because the checks inside it are mechanical and fail silently. Water purveyors mandate annual testing to protect the public supply from cross-contamination, and the requirement sits with the property owner.

What happens if I fail the test?

The assembly is rebuilt or replaced and retested. Purveyors typically give a short correction window, after which service can be interrupted — so do not sit on a failure notice.

Who can legally test my backflow assembly?

Only a tester holding the certification your water purveyor recognizes, using calibrated gauges. Ask for the certification number and the gauge calibration date.

How should a backflow quote be compared?

Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.

Who handles the permit for backflow in Utah?

The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.

What warranty applies to the work?

Whatever the contractor offers in writing — PlumberUtah is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.

How does the callback request work?

The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.

Which areas does PlumberUtah cover?

All of Utah: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
