Sprinkler Woes

This week I mowed the yard for the first time since buying our wonderful house. After I was done I laid down fertilizer and proceeded to water it in. I took the oportunity to watch the watering since normally it comes on in the early morning hours. As it worked its way to the side of the house, I noticed a nook that wasn't getting watered. I heard sprinklers working but nothing was getting wet. I peered over the neighbors fence and this is what I found.



Apparently the neighbors fence (presumably built sometime after our fence and sprinkler system were installed) is blocking the last two sprinklers in the line along the stone wall (indicated by the grey bar). Four times a week for 5 minutes I'm soaking the bottom of 6 feet of fencing.

The inspector never caught it because the sprinkler system was never tested. This was because the control box is located on the outside of the house and was locked, (the reason it was locked and on the outside the garage was because it served as a model home and people needed to adjust the settings without getting into the house.)

I haven't dug up the survey yet, but I'm pretty sure the fence is treading into my property.

A few co-workers pointed out that since it's my property, I have the right to tear it down. While true, I don't think that would be very neighborly. I suspect the easiest thing to do would be to moved the sprinkler line to my side of the fence.
