Understanding Backflow Prevention Testing
Understanding Backflow Prevention Testing
Backflow is when water literally flows backwards. This is due to pressure changes & can result in contaminated drinking water.
Backflow prevention leaks or failures can lead to pollution of the public drinking water and the consequent shutting off of your water by your local water authority.
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 street level public water supply pressure creating a vacuum.
This backflow would contaminate the public water source without a tested and compliant backflow preventer.
Backflow testing is a test of different pressures inside your backflow preventer. Different parts must open or close at a certain PSI.
Your backflow prevention device ensures that the pressure from the public water source is greater so that you do not risk contaminating the public water.
As a matter of state law, every county public health board throughout Southern California requires annual backflow device testing.
A leaking, broken or failed backflow will result in severe penalties in addition to the immediate shut off your water resources which could force your business to close for days.
County and city water authorities mandate annual backflow prevention testing to ensure compliance that protects our public water resources.
One Flow simplifies the backflow maintenance and compliance process by helping responsible businesses avoid violations and noncompliance when a new backflow device is installed, repaired, or relocated.
Our managed backflow testing and maintenance service manages every step of the local water authority compliance process and simplifies an otherwise complicated and time consuming process of backflow testing and maintenance.
