Backflow Information

What is a backflow and why should you care?

It is a condition where the water, or some other substance, in the plumbing of your building (residence, business, whatever) or a cross connection with another plumbing system(irrigation, chemical tank, LP tank etc.), flows backwards back into the city or county's water system.

So what's the big deal?

Well look at this...EPA Backflow Case Studies


What is a backflow preventer?

A backflow preventer is a mechanical device that prohibits a backflow of contaminants from getting into the drinking water. The principal types of testable backflow preventers used for medium to high hazard processes include: reduced-pressure principle assemblies, double check valve assemblies and pressure vacuum breaker assemblies. Non-testable devices used for low hazard processes include: residential dual check valves and hose connection vacuum breakers.


Why do backflow preventers have to be tested regularly?

Backflow preventers have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. Therefore, backflow preventers have to be tested regularly with calibrated equipment to ensure that they are functioning properly. Typically, backflow preventers are tested once each year.


Who is responsible for having a backflow preventer tested?

Generally, the owner of the residence, building or property manager is responsible for having the preventer tested.

Who can test backflow preventers?

Only an individual who is a Certified Backflow Prevention Assembly Tester and has been certified by the ABPA, is permitted to test and certify backflow preventers.

I have received a letter stating that my backflow preventer is due for testing, what am I required to

Contact a Certified Backflow Prevention Assembly Tester such as SB Landscapings Backflow Prevention Services Division to test the preventer.

What are the consequences for failing to comply with the testing request?

Failure to comply with the notification may result in discontinuation of water service.

What is the typical cost of a backflow preventer test?

The typical cost of testing a backflow preventer varies depending the type and size of the device/devices to be tested.
