What is Cross-Connection?

A cross-connection is any temporary or permanent connection between a public water system or the consumer’s water system (i.e., drinking) and any source or system containing non-potable water, liquid, solid or gas that could contaminate the potable water supply by backflow.

What is backflow?

Backflow is the undesirable reversal of the flow of water from its intended direction in any pipeline or plumbing system. Backflow is dangerous because it can allow drinking water in plumbing systems to become contaminated and unusable.

What are some examples of connections hazards?

Common examples of cross connection hazards (source of contamination) that need to be protected with a backflow preventer include:

Residential

  • Fire sprinkler system
  • Lawn irrigation systems
  • Auxiliary water supply (wells)
  • Hot tubs/spas
  • Swimming pools
  • Hose bibs/garden hose
  • Boiler

Commercial

  • Carbonation equipment
  • Film processors
  • Fire systems
  • X-ray machines
  • Dental equipment

The customer needs to eliminate as many potential cross connection issues as possible, but when you have an existing well or sprinkler system, an approved, properly installed and tested backflow prevention device must be used.

Examples of backflow devices:

  • Air gaps
  • Reduced pressure backflow assemblies (RPBA) Commonly used with existing wells
  • Double check valve assemblies (DCVA) commonly used in sprinkler systems

TEST & INSPECT YOUR BACKFLOW DEVICE

West Sound Utility District MUST inspect all new devices when installed. You can use any tester on our list, but if you use one not on our list, they must have a Washington State Department of Health Certification as a Backflow Assembly Tester (BAT) and the tester must provide us with copies of their current state certification and test equipment calibrations certificates.

Disclaimer: West Sound Utility District provides this list as a service to our customers. This is not a complete list of state certified testers, but rather a list of testers who have provided documentation that shows that all of their applicable certifications are current. The District does not warranty any work performed by anyone on this list.
