Annual Backflow Testing in Marysville
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.

Freeze and Heat Protection for Backflow Preventers in Marysville, 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.
