Backflow Testing

To keep your drinking water clean

Did you know that dirty water and contaminants can enter your water system through the very same pipes that transport your drinking water? In sections of your home’s water system where pressure is coming in the reverse direction, an alarming phenomenon known as ‘backflow’ can occur.

Backflow is when water from external sources – often dirty and non-potable – comes through your home’s irrigation system to enter your own water supply. Backflow tends to be caused by one of two reasons: water pressure in the reverse direction from the system’s intended use, and siphoning from a premature change in water pressure.

In order to prevent backflow from contaminating your water supply, it’s important to have annual backflow testing performed by a licensed professional, such as us!

Certified Backflow Testing

Backflow preventers installed on your sprinkler system prevent dirty water and contaminants from entering your drinking water and the city’s water supply. A backflow preventer is a one-way valve installed as a cross-connection between your water supply and your sprinkler system. Washington State requires that all cross-connections, such as a sprinkler system, have a backflow preventer. Annual testing of your backflow preventer is required by Washington State Code WAC 246-290-490 to ensure that it is working properly.

Our backflow testers have been certified through the Washington State Department of Health and are annually licensed. The test kits we use are annually calibrated.
