The water supply to the irrigation system includes a connection between copper and PVC pipes, located a few inches above the ground. The PVC pipe connected to the copper pipe (blue in the picture) runs underground through a straight connector (white in the picture), has a right angle elbow which after another several inches enters an access box. The interface between the copper and PVC pipes is leaking.
Are there concerns with cutting the pipe just below the current straight connector, and adding a new straight connector after attaching new PVC pipe to the copper pipe that is slightly longer than the existing pipe to push the copper pipe upwards to straighten the copper pipe? Or would replacing a longer section of PVC pipe (past the elbow) be more likely to prevent this from happening again?
