What Is a Backflow Preventer?

Water in a plumbing system is intended to flow in a particular direction. Backflow occurs when water moves in the opposite direction, potentially allowing water from a connected system to move toward the drinking-water supply.

A backflow prevention assembly is designed to help protect against that reverse flow. Certain plumbing connections require a backflow prevention assembly, and some testable assemblies must be inspected and tested periodically under applicable utility requirements.

Shaddai provides backflow prevention assembly installation, testing, repair, and replacement.

Normal Flow

Water travels in one direction from the utility supply through your plumbing to your fixtures.

Reverse Flow Protection

A backflow preventer helps stop water from moving backward toward the supply when pressure changes occur.

Annual Testing & Certification

Backflow Testing & Annual Certification

Backflow testing checks whether a testable prevention assembly is operating according to the applicable testing requirements. For properties with annual testing obligations, Shaddai provides testing and certification services and can help arrange recurring appointments. Shaddai also offers annual testing renewal reminders.

Testing and reporting requirements vary by water utility and property. Contact Shaddai to discuss the requirements that apply to your property.

Annual Testing & Certification

Need Your Annual Backflow Test & Certification?

Some backflow prevention assemblies must be tested annually to meet the requirements of the local water utility. If you've received a notice that your annual test is due, check the deadline and instructions provided.

Shaddai HL Plumbing performs backflow testing and certification and can help customers arrange recurring annual testing.

Step 1

Review Your Notice

Check the testing due date and any instructions from your water utility.

Schedule Your Test

Contact Shaddai to arrange backflow testing and discuss the applicable requirements.

Complete Testing & Documentation

Testing schedules and certification requirements depend on your water utility, property, and installed backflow prevention assembly. Requirements vary — not every property requires annual testing.

What Happens If a Backflow Assembly Fails a Test?

A failed backflow test means the assembly did not meet the applicable test requirements at the time it was tested. That does not automatically mean the entire assembly must be replaced. Depending on the problem and the condition of the device, repair may be possible. When repair is not appropriate, replacement may be necessary.
