Time for a PITA customer thread We did a retrofit on a badly installed system last week, added some heads, moved some heads, replaced some valves. Anyways, the owner would follow us around telling us dirty jokes and laughing at himself, it was really annoying. On occasion, he'd pretend to be smart, when I was nozzling up the heads he started pulling GPM numbers out of his rear and telling me that I was overusing the amount of water etc. Sometimes, you just want to look at them and ask them if they want a to install the system, or do they want a professional to do it. Right before we leave, he tells us that he learned everything he knows about irrigation from Jesse Stryker at http://www.irrigationtutorials.com While I think that Jesse Stryker is doing a great thing at that site, I'm mad at him for giving this PITA the confidence to think he knew what he was doing.
