Okay Guys, here's an interesting one for you. We installed a system about six months ago and used about 5000 feet of rainbird drip. Homeowner called about two months ago and said there was a leak. Went to fix it and discovered that some animal (squirrel, mouse, whatever) had chewed a hole in the pipe. Fixed that under warranty. Just went back yesterday and found six more spots where the drip had been chewed through. We install 1000's of feet of drip a year and I have never seen this. Any Ideas?? And would you continue to warranty the work?
