Backflow basics

What you
need to know

01
What is backflow?

Backflow is when water literally flows backwards. This is due to pressure changes & can result in contaminated drinking water.

02
How does it OCCUR?

For example: If the street supply suddenly had a break, the pressure at the street would be 0. At that point, YOUR pressure would be greater than the supply pressure creating a vacuum. This could suck up dangerous water without a backflow preventer.

03
What is backflow testing?

Backflow testing is a test of different pressures inside your backflow preventer. Different parts must open or close at a certain PSI.

04
when to test?

The plumbing code of every city in Los Angeles County California requires backflow testing annually.

This guarantees your device is stopping backflow. In addition, when there's a backflow installation, repair, or relocation, it needs to be tested.

At One Flow Los Angeles we truly care about the customer, because we're one too. We all share water & the responsibility to protect it.
