Did a large landscape job last spring. Had a guy put in a 5500 irrgation system. Did a bad job...but thought he had winterized as well. Got called to the site last week with a split copper pipe on the irrigation water meter!. After some more investigation found that the irrigation was in the ON position. What are may chances of have or not having broken pipe under ground??? I guess it was my fault I didn't check.....damn it!! What are my chances?????
