Understand the appointment

Testing the assembly that protects your water supply

Backflow is water moving in the wrong direction through a connection. A pressure change can allow water from an irrigation system or other connected equipment to flow toward the drinking-water supply. Backflow prevention assemblies help protect against that reverse flow.

Testing checks the assembly's operation. Repair addresses a problem with it. If you are calling about a leak, replacement, or a previous failed test, mention that when you speak with us so the office can discuss the right scope.

What to have ready

You do not need to know every technical detail to call. These basics help the office understand your request and identify what still needs to be confirmed.

01

Property and utility

Have the service address and water utility name ready. For a managed property, include the person who can approve the visit.

02

Notice and records

Keep the testing notice, its due date, and any previous report together. Mention whether this is a routine test or a follow-up to a failed result.

03

Assembly information

Share the location, number of assemblies, and any readable make, model, or serial number. A photo is useful if the label is difficult to describe.

04

Access arrangements

Let us know about a locked gate, pets, an indoor assembly, or an on-site contact. Ask whether anyone needs to be present and whether water use will be interrupted.

From request to test record

  1. STEP 1

    Discuss the request

    Call or use the form above. Let the office know the property address, utility, and notice deadline. Mention multiple assemblies or any known problem.

  2. STEP 2

    Confirm the visit

    Before booking, confirm availability, price, access needs, and what is included. Ask about the test report and any separate repair or retesting arrangements.

  3. STEP 3

    Keep the result

    After testing, retain your report. If further work is recommended, discuss the findings and next steps before authorizing it.

Common questions about this service

A tester uses a test kit to check how the assembly operates. This evaluates its protective components; it is different from taking a drinking-water sample or inspecting the rest of your plumbing.
Use the deadline on your water utility notice. If the notice is missing or unclear, contact your utility for the requirement that applies to your property. Tell our office the date when you request service.
Testing and repair are separate scopes. Tell us if you already have a failed test report, visible damage, or a leak. Ask the office to confirm what the appointment includes and how any additional work would be handled.
Start with your notice and any previous test report. Tell the office what information is missing. A clear photo of the assembly and its label can help the conversation; do not guess the model or take the assembly apart.
Confirm the reporting arrangements with the office before booking, including who sends the result to your water utility and how you receive a copy. Keep the report with your property records.
Call H2O or send a request with your contact details. Our office will confirm testing availability for your address, pricing, and appointment options. A request does not reserve a time until the office confirms it.
