Why Backflow Testing Is Required

Backflow testing is the process of inspecting and evaluating backflow preventers — one-way gate devices that ensure water flows from the municipal supply into your building, but prevent non-potable water, chemicals, or waste from reversing direction and contaminating the clean public water supply.

Both Oregon and Washington require property owners to complete an annual backflow test by a certified professional. Failing to meet your annual testing deadline triggers enforcement actions, beginning with warning letters but escalating quickly to substantial fines and, ultimately, disconnection of water services to your facility.

Who Needs Backflow Testing

Commercial Properties We Serve

Backflow assemblies are required anywhere a cross-connection exists, meaning any point where the potable water supply connects to a source of potential contamination.

Multifamily & Apartments

Property managers for apartment complexes and condominiums must ensure annual testing of all backflow assemblies serving common-area irrigation, boilers, and fire suppression systems.

Commercial & Retail

Office buildings, retail centers, and restaurants require certified backflow prevention on kitchen equipment, beverage dispensers, ice machines, and landscaping lines to meet health department standards.

Industrial & Manufacturing

Industrial facilities have the highest cross-connection risk. Chemical vats, processing equipment, and waste systems must be isolated from the municipal supply with tested, certified assemblies.

Municipal & Institutional

Municipal buildings, schools, hospitals, and government facilities face strict regulatory scrutiny. We manage complex multi-assembly portfolios with complete documentation for all regulatory bodies.

Hospitality & Hotels

Hotels and hospitality venues must protect guests from contamination across laundry systems, commercial kitchens, pool and spa equipment, and large boiler feeds.

Irrigation & Landscaping

Commercial irrigation systems are among the highest-risk cross-connection points: fertilizers, pesticides, and stagnant soil water can siphon back into drinking water without a tested, functioning preventer.

Repair & Replacement

Failed Test? We Fix It on the Same Visit

Mechanical devices wear down over time due to constant water pressure, mineral buildup, and degrading rubber seals. If your device fails the annual inspection, it must be repaired or replaced immediately to satisfy municipal requirements and keep your water on.

Because we dispatch fully stocked trucks and highly trained technicians, we can typically rebuild the internal components of a failing valve or perform a complete unit replacement during the same service visit, eliminating extended downtime and the cost of a return trip.
