Backflow Testing

To protect our drinking water you must have your backflow device tested annually by a State of Idaho licensed backflow tester as soon as you turn your lawn sprinkler system on. We encourage you to have your test completed early so that your tester can submit the results to the City of Gooding as early as possible. All tests are required to be completed by June of each year. If your device fails the annual test you will have 10 days to have it repaired or retested. If you are unsure whether you have a backflow device or if you need to have a backflow device please contact City Hall (208) 934-5669.

Questions & Answers

Q: Do I need a permit prior to the installation of my backflow device? 

A: Yes, you do need a plumbing permit. The plumbing permit is issued by the Idaho Division of Building Safety; (208) 334-3950 or 

Q: What is a cross connection? 

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

Q: What is backflow? 

A: Backflow is the undesirable reversal of flow of non potable water or other substances through a cross connection and into the piping of a public water system or consumers potable water system. There are 2 types of backflow; Backsiphonage and Backpressure. 

Q: What is backsiphonage? 

A: Backsiphonage is backflow caused by a negative pressure (i.e. a vacuum) in a public water system or consumers 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. 

Q: What is backpressure backflow? 

A: Backpressure backflow is backflow caused by a downstream pressure that is greater than the upstream or supply pressure in a public water system or consumers potable water system. Backpressure 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 a water main. 

Q: Why do water suppliers need to control cross connections and protect their public water systems against backflow? 

A: Backflow into a public water system can pollute or contaminate the water in that system and each water supplier has a responsibility to provide water that is usable and safe to drink under all foreseeable circumstances. Furthermore, consumers generally have absolute faith that water delivered to them through a public water system is always safe to drink. For these reasons, each water supplier must take reasonable precautions to protect its public water system against backflow.
