Backflow Device Testing

We are Oregon state certified backflow testers. Our job is to help ensure the safety of the public water system through backflow testing.

Having your backflow device tested has never been easier. Call us to schedule your test, in most cases you don't even need to be home. We will test your device, provide a copy of the test report to your water purveyor, leave you an invoice and a copy of the test report in a pre-paid self addressed envelope for your payment.

We will even keep track of the test date and notify you next year to see if you want us to test it again for you. Now that's easy, and it doesn't even require a button!

What is backflow, and why do I need a backflow prevention device?

A backflow prevention devices is a mechanical device installed between the public water system and a plumbing system.

Properly installed, tested and maintained, a backflow device can reliably prevent the backflow of water from contaminating the public water system.

Backflow occurs when water, instead of moving forward in the intended direction, starts flowing backwards into the public water system.

The two most common types of backflow are back pressure and back siphoning, which are the result of positive or negative pressures, respectively.

Back pressure could occur if a pump or other device is used to force water or chemicals into a plumbing system, and thereby contaminating the public water system by overcoming the distribution systems pressure.

Back siphoning occurs when there is a drop in the distribution system pressure, such as a water main break or even fire trucks using fire hydrants during a fire. This condition would allow possible contaminates from a plumbing system to be sucked into the public water system.
