View Full Version : Tree Roots & Their Effect on Pipes?

07-15-2008, 01:28 PM
I always wanted to know, should you ever be worried about trees and/or plants and their roots getting into the pipes of an irrigation system? If I'm not mistaken, a tree's roots can and will break into pvc pipes. Any advice on this topic?

I doubt roots can get "into" irrigation pipes. But I have seen pictures (perhaps on this forum) where tree roots have grown around a pipe. I specifically recall a picture of roots that had grown around copper pipe and simply crushed it.

My main consern when I was installing my irrigation system was tree roots growing between multiple pipes running in the same trench. I could then see the root swelling over time and either spreading the pipes or breaking them. That's why (if it will truly help... only time will tell) I lined the sides of my trenches with vinyl siding when ever I ran pipes anywhere near tree roots.

Yes they can crush and pinch and break pipes. Fixed one yesterday. Root grew over a tee fitting and pushed it down and broke it.

I've had to hack roots back that have collapsed poly pipe. Takes time for the roots to get there, but you can't stop the will of Mother Nature

Happens somewhat often with poly, usually not for 5-10 years though. Condos are notorious for them, with trees being planted in the curb boxes and such.

not the end of the world though.
