Commercial Backflow Requirements

 
Item

The City of Jacksonville and JEA both require that all commercial water services require a backflow preventer device unless specifically exempted. Backflow preventers are required to be installed on the customer’s property within 10 feet of the JEA meter and in accordance with manufacturers’ instructions for the specific application. Any variance from installation requirements must receive prior approval from JEA. The State of Florida also requires that most commercial premises install and maintain a reduced backflow preventer unless the business requests and receives an exemption from JEA. 

The City of Jacksonville Building Inspection Division requires the installation of backflow preventers on all commercial fire sprinkler service lines, irrigation lines and potable (domestic) water lines.

JEA’s Cross Connection Control Policy requires the installation, maintenance, and annual testing of Reduced Pressure (RP) backflow preventers on all commercial JEA water services within 10’ of the JEA meter; or, in the case of unmetered services, immediately upon entering the customer’s property. All backflow preventers must be installed according to manufacturer’s specifications. Any deviation from these requirements must receive prior approval from JEA.

Closed Title:Reduced Pressure Backflow Preventers
Open Text:

In most cases, commercial customers must have a reduced pressure backflow preventer assembly installed. In the case of fire sprinkler lines where pressure is a factor, a double-check assembly may be installed – unless there is a retention pond or well on site that holds water for more than 24 hours or the property’s structures are three or more stories and use a booster pump. In those cases, the customer must install a reduced pressure backflow preventer.

A reduced pressure backflow preventer is required when there is a retention pond on site that holds water for more than 24 hours, or when the service is for a building of three or more stories that uses a booster pump.

Closed Title:Containment Devices
Open Text:

A containment program is designed to protect the public water supply. JEA is responsible for tracking the installation and annual testing of containment backflow preventers.

JEA requires containment devices to be installed on all dedicated irrigation or fire sprinkler lines and on most potable (drinking) water supply pipes. Containment backflow preventers are located near the customer’s connection to the JEA water supply, typically within 10 feet of the JEA water meter. All containment devices must be certified as functional, with the test results submitted to JEA annually. 

For premises with both isolation and containment devices, JEA requires only the containment backflow preventer (near the water meter) to be certified annually. Test reports for isolation devices do not need to be submitted to JEA.

Accordion Item
Closed Title:Isolation Devices
Open Text:

An internal, or isolation, program protects the occupants of a building from contamination or pollution from internal processes. 

Isolation backflow preventers are internal devices that are not located near the JEA water supply pipe. They isolate potential hazards in one area from other areas of the customer’s water system. JEA policy does not require installation, maintenance or annual testing of isolation (internal) backflow preventers. Installation and testing of these devices may be required by other entities, however, such as the local plumbing code, health department regulations or fire codes. Under most circumstances, commercial customers do not need to submit annual certification reports for isolation devices to JEA.

For premises with both isolation and containment devices, JEA requires only the containment backflow preventer (near the water meter) to be certified annually. Test reports for isolation devices do not need to be submitted to JEA.

Closed Title:Wet Pipe Sprinkler Systems
Open Text:

Fire sprinkler systems may present a hazard to public drinking water supply. Standing water that collects in the pipes can corrode metals, contaminating the water dispersed by the sprinklers. For this reason, fire sprinkler systems are required to have approved backflow preventers installed and maintained.

Location Scenarios

  • Sprinkler system fed by dedicated pipe: The preventer will be on the customer’s property and within 10 feet of the JEA distribution connection.
  • Sprinkler system fed from the same meter as the drinking water: The preventer must be installed in either one of the following locations:
    • On the customer’s property no farther than 10 feet from the JEA water meter
    • On the customer’s sprinkler system at the point where it first branches off from the customer’s main water supply pipe. Placement in this location protects both the customer’s drinking water and the public system from potential contamination.

Closed Title:What is a backflow preventer, and what does it do?
Open Text:

A backflow preventer is a device that allows water to flow from JEA into your building, but never in the opposite direction. It’s designed to prevent drinking water from being contaminated due to backflow, or introduction of various substances such as cleaning solutions, fertilizers or human waste into the public water supply. 

Accordion Item
Closed Title:I didn’t know I had a backflow preventer. Where is it?
Open Text:

Backflow preventers must be located within 10 feet of your JEA water meter. For fire sprinkler services, it should be at the point the water service enters your property.

Most backflow preventers are located outside. However, some backflow preventers are indoors, such as in dedicated fire service rooms. Qualified JEA backflow testers will know where to find them and understand backflow preventer requirements. You or your tester can also contact the JEA Cross-Connection Control Team at the number provided below for more information. If your commercial JEA water service does not have the required backflow preventer, one must be installed.

Closed Title:Can you send someone to locate the meter/backflow preventer?
Open Text:

For meter or water line locates, please contact 904-665-6000. JEA Cross Connection Control has locations for many of our customers backflow preventers. Please contact us at 904-665-4410. If we don’t have that information already available, we will schedule an on-site visit to help locate the device.

Closed Title:Who is responsible for testing backflow preventers?
Open Text:

The customer identified on the JEA bill for the water service is considered the responsible party

JEA does offer a Commercial Backflow Preventer Program, so you can stay up to date on testing and avoid disruption of services. We’ll automatically schedule your annual backflow preventer testing. And once your test is complete, you’ll receive a notification with the results. Customers who are interested should contact backflow@jea.com or call (904) 665-4410 to enroll.

Accordion Item
Closed Title:Which backflow preventers need to be tested?
Open Text:

All JEA commercial water services must have a backflow preventer. This includes, but is not limited to potable water, irrigation, and fire services. Backflow preventers on commercial services must be tested annually, and immediately following an installation, repair or replacement. 

Accordion Item
Closed Title:I had my backflow preventer tested less than a year ago. Why do I have to test it again?
Open Text:

Backflow preventer tests are due on the anniversary date of their first test. For example, if the test month is October but you tested late, for example in December, the next test is still due in October of the next year.

Accordion Item
Closed Title:This service is inactive, why do I still need to test the backflow preventer?
Open Text:

If the water service is not locked off, or the meter removed by JEA, it is still considered connected to the water system and a backflow event or cross connection can still occur, if a properly functioning backflow preventer is not installed.

Accordion Item
Closed Title:I just received a notice from JEA that my backflow preventer needs to be tested. Why is testing needed?
Open Text:

Properly installed and maintained backflow preventers protect our drinking water supply and help ensure all JEA customers have a reliable source of clean water. JEA and Florida law require water service customers maintain backflow preventers on their JEA water service lines. Annual testing is part of this maintenance requirement.

Accordion Item
Closed Title:I’ve received several calls from JEA and vendors about my backflow preventer. Why so many calls? And are these vendors legitimate and qualified to conduct tests?
Open Text:
JEA sends emails and automated phone calls to each commercial customer with a backflow preventer(s) due for testing. JEA Qualified Vendors also may contact you to schedule testing. You are not required to hire any vendor that contacts you. However, the vendor you select must be a JEA Qualified Vendor.
Accordion Item
Closed Title:How much does a test, repair or installation cost?
Open Text:
Costs vary from vendor to vendor and generally differ based on the type, size and location of the backflow preventer. JEA recommends contacting multiple vendors to compare pricing and capabilities.
Accordion Item
Closed Title:My backflow preventer failed. What do I need to do?
Open Text:

If your backflow preventer fails, it means that it is not operating properly and poses a potential threat to the community water system. The responsible party must ensure that the necessary repairs and confirmatory sampling are completed within 30 days of receiving the failed test. If it can’t be repaired, it must be replaced. Either way, it must be retested.

If your system requires repairs or replacement, one of JEA's qualified backflow testing vendors may offer these services. Please contact them for more information.


Accordion Item
Closed Title:My backflow preventer failed and the testing vendor says I have to replace it at a cost. Can it be repaired instead?
Open Text:
Under most circumstances, backflow preventers can be easily repaired. However, because they are mechanical devices with moving parts, more significant repairs may be needed. Complete replacement should be a rare occurrence. JEA recommends contacting multiple vendors for pricing and/or a second opinion if desired.
Accordion Item
Closed Title:My backflow preventer passed but I keep getting reminder notices. Why?
Open Text:
JEA Qualified Vendors must send backflow preventer test reports within 30 days. If you’re still getting notices, your backflow preventer may have failed, or the vendor has not submitted the report. JEA recommends contacting your vendor directly. 
Accordion Item
Closed Title:What happens if I don’t comply with tests, or repair or replace a faulty backflow preventer?
Open Text:
JEA may arrange for a backflow preventer to be tested, then add the testing cost to the customer’s utility bill. Customers who do not comply also may incur penalties or fines and may risk discontinuation of their utility services. JEA only uses these actions as a last resort to ensure the safety of the public water supply. 
Accordion Item
Closed Title:Can’t JEA just do this for me and bill me?
Open Text:

JEA offers a Commercial Backflow Preventer Program, so you can stay up to date on testing and avoid disruption of services. We’ll automatically schedule your annual backflow preventer testing. And once your test is complete, you’ll receive a notification with the results.

Customers who are interested should contact backflow@jea.com or call (904) 665-4410 to enroll.

Closed Title:I am just a tenant and not the building owner. What do I need to do?
Open Text:
JEA considers the recipient of the monthly bill the responsible party. You may wish to contact the building owner/management company to determine the correct course of action.
Accordion Item
Closed Title:Why has the need for testing not been emphasized in the past?
Open Text:
The protection of the public water supply has always been one of JEA’s highest priorities. JEA has sent annual reminder letters to all commercial water customers for several years.  We are also working to increase awareness through customer education programs.

Closed Title:When I see one dripping along the side of the road, etc., is that ok? Who should I call?
Open Text:

Backflow preventers are the responsibility of the customer. A dripping or leaking device is an indication that it is not working properly. If you don’t want to contact the customer directly, you can contact JEA Cross Connection Control at 904-665-4410 and we will reach out to them.
