Hey everyone! I'm building a new house and I've come across some info about backflow preventers being essential for irrigation systems. I asked my builder, and he said a backflow preventer isn't necessary since my irrigation system runs on its own water line. Can anyone share their thoughts or experiences on this? Is my builder correct?

If I was in your shoes, I'd definitely want a backflow preventer installed. I've seen a sewer backup in our area that caused a lot of damage, but the previous owners of my house had a backflow preventer, which saved us from a nasty situation. It's a small investment that can save you big-time in the long run!
From what I understand, it really depends on what your builder means by 'runs on its own water line.' Even if it does, there's still a chance of water contamination. A neighbor of mine has a professional sprinkler system with a solid backflow preventer to avoid any issues, so I’d be cautious here and would recommend getting a pro opinion.
From my experience in installing and maintaining these systems, many municipalities require a backflow preventer for any underground irrigation systems using city water. It’s there to prevent contaminated water from going back into the city's supply. But if your system uses well water, you might be good without it. It would be best to check this with your local water authority to be sure.
