Backflow Assembly

Your backflow preventer is designed to keep water flowing in just one direction, which keeps the water in your home or business from getting contaminated. At AAA, we provide backflow preventer testing, maintenance, and repair.

The Importance of Backflow Testing

Backflow preventers are designed to keep the water that flows to your home or business moving in one direction. In doing so, they stop backflow and prevent contamination of drinking water. That’s why most city water utility organizations require annual testing to verify that your backflow preventer is working properly. Our team at AAA Fire Protection offers backflow testing, as well as repairs and maintenance, to ensure that your backflow preventer is in compliance. We’ll even file backflow test reports on your behalf, to keep your system in good standing with the city.

Backflow Testing with AAA Fire Protection

Backflow testing is a relatively quick process – often, it takes our team only ten minutes to complete. When you schedule a backflow appointment, one of our certified technicians will come out to perform the test. However, if your backflow preventer is located in a particularly tough spot to access, two technicians may be needed. The technician performing the test will then attach hoses to check valves on the assembly to determine water pressure in various areas of the apparatus.

We Assess Backflow Assemblies For:

  • Fire Sprinklers
  • Irrigation Systems
  • Domestic Pipe Systems

Our story began in 1954. Family-owned and operated with headquarters in Seattle for over 60 years, we’ve grown to become a name synonymous with fire protection in the Northwest. Providing one of the most comprehensive service and product offerings in the region, backed by the largest fleet of service technicians, we stand ready.




If you have an RP type backflow preventer, you may notice that there is leakage from the check valves. However, if you don’t have an RP backflow, there may not be any external signs that your backflow preventer isn’t working properly. That’s why it is so important to complete annual testing.

We've used AAA Fire Protection for longer than the 27 years I've worked here. We don't have to remember - they show up when it's time to service our fire extinguishers, replace them as needed, and make other suggestions as needed. We've been very happy with them!
