Hi All- I modifying an irrigation system for a homeowner who is adding sod where a planting bed once stood. I will be removing an existing rotor and putting in 2 new rotors in it's place to cover the existing area plus the new sod area. The main supply trunk appears to be 1 inch tubing and the existing rotor was split off using a 1,.5,1 T-fitting with the rotor being connected off the .5 inch reduction on the T. The two new rotors will be about 15-20 feet away from the original rotor. My question is if I need to run 1 inch line from the exiting T location to the new rotors and then reduce them to 1/2 inch or if I can just take the existing 1,.5,1 T-fitting and run 1/2 inch line directly to each of the new rotors that are 15-20 feet away. Is that too far of a run? Just running the 1/2 inch line would be easier because I can use the existing fitting but don't want the new rotors to be undersupplied and would rather do 1 inch line if that's appropriate. Thoughts?
