FAQ

clean water

What is backflow?

Backflow is the undesirable reversal of flow of nonpotable water or other substances through a cross-connection and into the piping of a public water system or consumer’s potable water system. There are two types of backflow--backpressure backflow and backsiphonage.

What is a cross-connection?

A cross-connection is any temporary or permanent connection between a public water system or consumer’s potable (i.e., drinking) water system and any source or system containing nonpotable water or other substances. An example is the piping between a public water system or consumer’s potable water system and an auxiliary water system, cooling system, or irrigation system.

What is backpressure backflow?

Backpressure backflow is backflow caused by a downstream pressure that is greater than the upstream or supply pressure in a public water system or consumer’s potable water system. Backpressure (i.e., downstream pressure that is greater than the potable water supply pressure) can result from an increase in downstream pressure, a reduction in the potable water supply pressure, or a combination of both.

Increases in downstream pressure can be created by pumps, temperature increases in boilers, etc. Reductions in potable water supply pressure occur whenever the amount of water being used exceeds the amount of water being supplied, such as during water line flushing, firefighting, or breaks in water mains.

What are some of the State and Federal regulations and codes that I may need?

The Safe Drinking Water Act (PL 96-523)
Florida Regulations – Chapter 403.850–403.864
Chapter 17 – 22, F.A.C.
Federal Department of Environmental Protection Regulation
Codes 62-550.200 (16) FAC, 62-555.360 (1-7) FAC

Is it required to test my commercial and industrial Backflow Devices?

The testing of all commercial and industrial backflow devices is required by your water districts cross-connection control program, which is enforced by the Federal Department of Environmental Protection Agency, and “The Safe Drinking Water Act.” All residential properties must comply by 2009. All paperwork is forwarded to the water purveyor for your convenience and a copy is sent to you for your files.

It is required that a successful test of this device must be completed and sent to the cross-connection control department for your city or county by this date. Failure to have this test performed will result in the termination of your water supply.

What is backsiphonage?

Backsiphonage is backflow caused by a negative pressure (i.e., a vacuum or partial vacuum) in a public water system or consumer’s potable water system. The effect is similar to drinking water through a straw. Backsiphonage can occur when there is a stoppage of water supply due to nearby firefighting, a break in a water main, etc.
