Irrigation Meter, System, and Backflow Question
Building a house in Jefferson Parish (Kenner). I got a 2nd water meter for irrigation and future pool. Does JP/Kenner require a backflow on the irrigation meter if it's not tapped into the main line? I'm trying to figure out why I would need a backflow installed on the main line if the irrigation system is going to be installed on the 2nd meter? Help.

Yes, I believe that is a department of health and hospitals requirement.

Not sure what you’re asking with the way you worded it but yes You are going to need a backflow on your irrigation meter. City main->irrigation meter ->backflow.

We have a second meter for pool and irrigation and we have to pay for annual inspection of the back flow preventer. We aren’t in Metairie but the form suggests it’s a state rule.

re: Irrigation Meter, System, and Backflow Question
You would still need a backflow. The irrigation meter is still connected to potable water so the backflow is required to separate potable from non-potable water (irrigation)

You absolutely need a backflow preventer as the line is still connected to potable water source. It isn’t that expensive to have one out in all things considered.

re: Irrigation Meter, System, and Backflow Question
The backflow preventer is to protect the municipal water supply from your irrigation system siphoning pesticides, etc. from your lawn. When you complete the irrigation system, the plumber that filed for the meter will need the serial number off the backflow prevention device. Jefferson Parish does not yet require annual inspections for residential backflow preventers but you can bet it coming. Orleans Parish has been doing it for a number of years.

Generally its a good rule. As someone said earlier pesticides could be an issue. The biggest problem could come from swimming pools with contractors/homeowners piping up pool pumps incorrectly and dumping pool into water systems.

Yes, you will need a back flow preventer and a person or co licensed with the city to install it

You will need a backflow preventer, and when you need it tested annually, look up $50 Backflow Testing.

They're name says it all.
