Just a question regarding a repair. Back in the late fall my sprinkler guy came to winterize our system. Well when he started to blow out the lines I noticed a break in the lines from a geyser that poped up. I asked him to repair it, but he kinda did not want to do it and said he would come back in the spring. So anyway I kinda figure now that I am going to have to fix this break any pointers on how to do it? How long do sprinkler lines last?? I think my system is about 8 years old..
