What we Do
We provide conveniently scheduled backflow testing and repair services to North Central Washington. We handled all of the paperwork and processing for your convenience. Copies of all necessary documents are sent to the water provider, a copy is sent to you within 48 hours of service and an additional copy is maintained in our files for future reference. We also offer a free annual reminder service, giving you a heads-up when it comes time to have your backflow assembly tested again.
What is backflow?
Backflow is the undesirable reversal of flow of water in a plumbing system due to either backsiphonage or backpressure. Backflow can result in contamination of the water supply through an unprotected cross-connection.
Backsiphonage occurs when there is a large reduction in pressure within the distributing pipes of the water system which creates a partial vacuum. A water main break or a large volume of water being used to fight a fire can lead to reduced pressure conditions in surrounding distribution lines.
Backpressure is a source of pressure, such as pumps or thermal expansion, which exceeds the operating pressure of the potable water supply. The higher pressure literally pushes the fluid or gas back into the water system.
We test the backflow assembly, and if the device is working properly, we move onto documenting the results.
We handled all of the paperwork and processing for your convenience. Copies of all necessary documents are sent to the water provider, a copy is sent to you within 48 hours of service and an additional copy is maintained in our files for future reference.
If the initial test of the backflow assembly does not pass, often all that is required is opening up the assembly and cleaning/inspecting the internal components.
We also offer a free annual reminder service, giving you a heads-up when it comes time to have your backflow assembly tested again.
RETEST FAILED DEVICE
If no obvious deficiencies are found while cleaning, the assembly is put back together and retested. Many times this is all that is required and the device will pass. Cleaning and retest is included in the cost of the test.
If the device fails the second test after a thorough cleaning and reassembly, we will troubleshoot the issue and provide you with an estimate to complete the repair. No work will be performed before you have reviewed and accept the estimate.
What is a backflow prevention assembly?
A backflow prevention assembly is a mechanical device that permits water to flow only in the intended direction. The assembly prevents the reversal flow of water or other substances from entering the potable drinking water system. Backflow assemblies are designed to be tested and repaired inline. They are to be tested upon installation and annually thereafter to ensure that they are functioning correctly and protecting the drinking water system.
Is this a new requirement?
Cross connection control regulations first began in Washington State in 1971. As directed by the Washington State Department of Health, the City of Wenatchee implemented a Cross Connection Control Program in early 2003 with the passing of Ordinance 2003-03. The State of Washington Department of Health WAC 296-290-490 is the governing code that requires the city to enforce protection of the public water system from contamination and pollution due to cross connections.
How do I know if I need a backflow prevention assembly?
When a facility or residence has been identified as having a potential hazard to the water system, a survey of the property is performed. A certified Cross Connection Control Specialist must perform the survey and based upon the finding require corrective action if needed.
