Freeze and Heat Protection for Backflow Preventers in Auburn, WA
Above-ground backflow assemblies are exposed to summer sun and winter cold. Eastern and mountain areas of Washington freeze regularly and deeply, so insulated pipes and winterized irrigation systems are standard. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last longer.
Annual Backflow Testing in Auburn
Most water providers require backflow assemblies to be tested at least once a year. Our certified testers connect a calibrated differential pressure gauge and check each check valve and relief valve. Test results are recorded on the provider's form and submitted for you. If the assembly passes, you are all set until next year.

Frequently Asked Questions About Backflow Preventer in Auburn
Annual residential backflow testing typically costs $75 to $150 per assembly. Repairs with a rebuild kit usually run $150 to $450. New residential installation ranges from $300 to $1,200, and commercial RPZ assemblies often cost $1,500 to $5,000 installed.
FHN Plumbing stands behind our work with a comprehensive warranty on parts and labor for all backflow preventer services. The warranty period will be outlined in your service agreement, but generally, new installations come with a manufacturer's warranty on the device and our warranty on the installation.
A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan. Eastern and mountain areas of Washington freeze regularly and deeply, so insulated pipes and winterized irrigation systems are standard. Regular testing and maintenance help lengthen its service life.
An RPZ, or Reduced Pressure Zone assembly, offers the highest level of protection, suitable for high-hazard cross-connections. A DCVA, or Double Check Valve Assembly, provides moderate protection and is typically used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code requirements.
Most municipalities, including Auburn, require backflow preventers to be tested once a year. This regular testing makes sure the device is working correctly and continues to protect your potable water supply from contamination, as required by local water authorities.
Water providers may send follow-up notices, charge fees or eventually suspend service. Scheduling early avoids these problems. We can often fit urgent tests in on short notice.
We service Watts, Febco, Zurn Wilkins, Apollo and other common brands. Our trucks carry rebuild kits for popular models. Less common parts can usually be ordered quickly.
A standard test usually takes 20 to 45 minutes per assembly. Water is briefly shut off during testing. Repairs may add an hour or more.
