I am starting a job tomorrow that i am not looking forward to. They have had an underground sprinkler system for eight years and they decided to put a pool in there back yard. Didn't call or anything just starting digging and installed the pool and covered all pipe that was hit. I have a feeling this isn't gonna be fun at all. Don't have a clue where anything is. How would you guys go about doing this? It would probably be easier and cheaper to install a new system wouldn't it. Also beside the pool they build a log cabin for a catering business. Basically took up the whole back yard. there was appr. seven zones in the backyard. Single strand wire and the mainline come from both directions and met in the backyard to go into there garage.
