What is Backflow?

Backflow is the reversal in the direction of the normal flow of water in a piping system. This can be caused by backsiphonage or backpressure. A negative or reduced pressure in the supply piping causes backsiphonage much the same way as drinking through a straw. Potential for backpressure backflow exists wherever there is a heating system, elevated tank, or other pressure producing equipment. When the pressure is reduced, the flow in the supply piping is reversed.

Does water really flow backwards?

Yes, it does happen. When the public water distribution system is in normal operation, water flows directly from the Marion Utilities' water main to your property. However, in certain situations backflow can occur causing water to flow back into the distribution system. The most likely time for this to happen is during periods of high water usage such as when fighting a fire, flushing a hydrant, water main breaks or repairs in the water distribution system.

​What is a backflow prevention device?

A backflow prevention device is a plumbing mechanism that provides a physical barrier to prevent the possibility of backflow from occurring and potentially polluting or contaminating the public water supply

Why do I have to test my backflow prevention device?

Backflow prevention devices are required to be tested annually because they have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. Therefore, all backflow prevention devices have to be tested annually to ensure they are functioning properly to protect the public water system.

How often do I have to test my backflow prevention device?

​Backflow prevention devices (of all types) are required by Indiana (see Indiana Administrative Code 327 IAC 8-10) to be tested annually, and are considered past due the following calendar day after the test due date.

Who can test my backflow prevention device?

​Testing must be performed by a State Certified Backflow Tester. Download a list of companies that offer this service or find a list at https://www.aquabackflow.com/backflow-testing-companies/.

Does Marion Utilities earn revenue from this program?

Marion Utilities does not earn any revenue by implementing and enforcing this program. Revenue associated with this program is contained within the private sector (Backflow Testers/Plumbing Companies & Aqua Backflow.) We realize and understand that there is an expense and inconvenience involved with complying with the requirements. However, protecting the public water supply is everyone’s responsibility and at Marion Utilities, we take our part very seriously.

Why has Marion Utilities decide to hire an outside vendor to help manage the program?

Marion Utilities has contracted with a firm called Aqua Backflow to help improve the efficiency of our customer communication, notification, and test results submittal process. For several years our staff manually entered the results of tests sent to us into our backflow management software. As our utility grows and we begin to protect more service lines, this task becomes increasingly cumbersome and is better managed by a firm that specializes in this process.

Where do I submit backflow prevention device test results?

You must be a State Certified Backflow Tester to submit your test results online at www.trackmybackflow.com. A water utility customer may not submit the results on the tester’s behalf. Additionally, if you send a copy to Marion Utilities or Aqua Backflow’s office, this does not guarantee that you won’t receive a non-compliance notice.

​Marion Utilities may terminate water service for a customer who is found to be in non-compliance. You will receive multiple notices prior to the ultimate disconnection of your water service.

I've received a Final Disconnection Notice, Recorded Message, or Red Tag. What do I need to do?

If you have received a Final Disconnection Notice, Recorded Message, or Red Tag related to backflow prevention compliance, we suggest you schedule testing with a State Certified Backflow Tester immediately to avoid interruption in your water service.
