They are completing reconstruction the street is front of our house so I now have to reinstall the sprinkler system along the new curb line The road layout changed so the system also needs to be redesigned to refect the new lay out. I always thought the previous head locations were too far apart (toro heads) for maximum coverage. I will now be putting in hunter pgp's instead of the old toro heads which I never liked from day one because they are so user unfriendly. Our system is on the city water system with a 35-40 gallon per minute water pressure. The lines are 3/4" feeders. What would you recommend for spacing the heads? Also, because of the road layout change I need to put an additional head in one zone. The zone I'm considering currently has five heads. The heads are each feed with a there own seperate 3/4' lines coming from the mainline at the valve box area to their respective curb locations. Do you think it adviseable to just add an additonal line off of one of the current seperate lines to feed this new head. Thanks for the help. It should be fun trying to get new sod to go in this heat. Add the draught were are experencing here in the Twin Cities, I figure the timing couldn't be worse.
