I recently subbed out the irrigation on a landscape project. The guy put in a hunter system - when it went live, the water was just barely coming out of the heads (spray heads and rotators). There are 6 zones with about 11 heads to a zone with a water pressure of 70 psi. This guy has no idea why the lack of water coming out of the heads, the risers are popping up mabey half an inch, instead of 4 inches on all zones. I don't know much about irrigation at all, but I figured there must be a leak- I dug down at the heads, and they weren't even tight, and the elbow connection was barely on, causing water to dribble out of the connection. Well, I thought that would help with the pressure, but it didn't. The irrigation guy came by yesterday while I was at another job site, and put in Rain-bird emmiters or something that supposedly lets less water out of the heads, causing an increase of pressure. Does this sound legit??! The pressure still sucks, and there are 3 different types of sprays comeing out of a high profile area on a commercial property. What is my next option? The irrigation guy thinks this is ok, but as a landscaper, it looks like crap. Should I call Hunter, and see if a rep. could take a look at it, or have the guy re-do it? I don't want to use this guy again, so if it needs to be redone, I don't want him touching it. Also, the guy wants to get paid for the install, and wants reimbursement for the rain-bird emitter things he put on the Hunter system. As pro's, what would you guy' do!!!!???
