Backflow Prevention
Backflow preventers are the first line of defense in ensuring we have clean drinking water. Backflow, or reverse flow of water in a plumbing system, can contaminate drinking water with non-drinking water from water pumps, fire sprinkler systems, irrigation systems, and/or wastewater systems. Although the backflow preventer is a simple device, its function is critical in preventing water from flowing backward and acts as the first line of defense against the possible threat of drinking water contamination.
Whether at your home or your place of work, to keep water safe from possible contamination the backflow preventer must be routinely tested and inspected.
Every backflow preventer has unique testing procedures and intervals of inspection, let our certified backflow technician perform the required inspection and testing. We will provide you with the inspection results, and in the event, our team members identify a problem we will recommend a course of action to correct/repair the problem.
If you would like to learn more or would like to schedule a backflow device test, contact our team at 503-231-0535, or visit our contact page to send us a message. A member of our team will get back to you as soon as possible.
