How To Repair A Damaged Pipe In A Lawn Irrigation System
Possible causes for damaged irrigation pipe include frost and frozen water damage, cracks or holes caused by lawn equipment or edging, damage from deep-growing roots, bad installation or defective pipes and fittings.
Recently on a sump pump installation where I was digging a trench, I punctured a lawn irrigation pipe, and needed to repair it before filling the trench back in.
Shut Off Water and Expose Break In Pipe
The first step in learning how to repair lawn irrigation pipe is to turn off the water and expose the pipe past the damage, six inches on either side is more than enough.
Once this is done I cut the damaged pipe out with pvc pipe cutters.
This 1″black “poly pipe” is flexible irrigation pipe which comes in rolls in sizes from 1/2″ to 2″.
Advantages include light weight, flexibility and easy no-glue fittings. The main drawback is that the pipe is simply not as rugged as PVC, and poly systems generally will not last as long. Contractors like using it because it can be “pulled” or plowed easily and quickly with a specialized machine and is cheaper to install.
