 WHAT IS A BACKFLOW PREVENTER?

A backflow preventer is a device that stops water from flowing backward into your drinking water. ‘Backflow’ means water flows in the wrong direction in your plumbing. This can let chemicals, bacteria, or other pollutants enter your clean water supply.

1. HOW OFTEN SHOULD A BACKFLOW PREVENTER BE TESTED?

In California, local rules decide how often you need backflow testing. Most areas require a test once a year. Water agencies use these rules to keep your water supply safe. It is important for property owners to follow these testing requirements.

HOW LONG DOES IT TAKE TO TEST A BACKFLOW DEVICE?

A backflow test usually takes 15 minutes to an hour. The exact time depends on the device and location. A certified tester should perform the test as required by local rules. Regular testing keeps your backflow preventer working and your water safe.

WHAT IS A CROSS-CONNECTION?

A cross-connection is when drinking water connects with water that is not safe to drink. This can cause contamination and harm public health. Cross-connections are a serious water safety risk in homes, businesses, and industrial sites.
